11 NOTE Depending on your computer OS, the above screen may look different. Also, appearance of your GUI will depend on the type and version of your web browser. Please contact Solectek sales and support for detailed information. The access username is admin and the default password is admin. Default Radio Log-in Info User Name Password admin admin Click OK on the above Windows screen and the Status->Overview screen will be displayed, as shown below (base unit version). The details will be reviewed in a later section. 11

12 4. Bench testing Before mounting units into their final location, it is recommended that the system be bench tested to verify basic operation. The following bench test steps are suggested: Setup. Each radio should be connected and physically arranged per the following sections, with a laptop or PC connected to each radio directly (or through a hub/switch). NOTE If you use WiFi connections, you do not need to use a laptop connection to the radio. Once you have powered up the radio, you can use a smartphone or tablet to access the user interface. See the following section of WiFi Management for details. WARNING DO NOT connect two radios to the same switch or a loop will be created, which will create a failure of the link. NOTE Make sure that all of your radios in the multipoint network share the same Link ID, bandwidth, data rate and security settings. Access Control List (ACL) is enabled as a factory default setting. It is also important to have identified and prepared the antenna, RF coax and Cat5e cable solutions that will be used in the intended application. Positioning. It is important to remember that the SkyWay radio and antenna system generate and transmit a great deal of RF power. During bench testing, antennas should not be pointed directly at each other. Rather, establish a position so there is approximately 180 degrees angular separation and 6 to 10 feet between units. Fine tune the antenna position so that the Local RSSI is between -30 and -60 dbm. Testing. If the system has been properly configured, the radios will begin communicating immediately. The following steps are recommended to verify operation: Link State. On the Main Status screen, verify that the RF Link State is Green (connected). 12

13 Local ping. From each laptop/pc be sure a ping to the local radio is successful. Link ping. Now ping from one laptop/pc to the other laptop/pc. This will verify the endto-end link. Traffic test. Using IPERF or equivalent utility, verify traffic can be passed successfully across the link. NOTE - Keep in mind that the SkyWay-Essence data rates will stress the performance of the PC hardware, operating system and IP stack. To ensure that this test equipment is not a performance bottleneck, pre-testing PCs, by connecting them directly to each other, is strongly recommended. NOTE -Using a file transfer to a shared volume or an FTP session on a typical Windows/Intel machine is not adequate to accurately measure throughput. NOTE - Units bench tested in an indoor configuration should not be expected to deliver full rated throughput. Benchmarking is typically performed after a system is deployed. WARNING When it is not in use, all optional ports must be plugged in so that there is no water intrusion damage to the unit. All optional ports with weather glands come with weather plugs and all optional RF ports come with weather caps. 5. Physical Installation 5.1 Introduction Your SkyWay radio is designed with a mounting system with two degrees of freedom. The radio can be mast, tower, pole or wall mounted using the appropriate hardware. After determining the best location for your radio, installation can begin. 13

14 To mount a SkyWay-Essence radio unit, both the mast mounting kit and Ethernet cable feedthrough need to be correctly assembled. The recommended approach consists of 3 or 4 steps, detailed in the following sections: Ethernet cable / feedthrough assembly Bracket preparation Mounting Antenna mounting (for connectorized units, only) With the exception of the CAT5 cable, all parts and hardware described in the following sections are included with your SkyWay radio. 5.2 Ethernet Cable / Feedthrough Assembly Only a single Ethernet cable is needed to connect the SkyWay radio to the indoor PoE Injector. Since the cable is exposed to the outdoor elements (heat, moisture, and UV light), only outdoor rated, shielded Cat5 Ethernet cable should be used. To ensure all-weather operation, the weatherproofing cable feedthrough (also known as grommet or gland) must be properly assembled onto the Ethernet cable and radio. The following diagram depicts each of the feed-through parts: Assembly Steps: 1. Remove the Compression Nut and slip it over the Ethernet CAT5 cable as shown below. 14

15 2. Feed the Ethernet CAT5 Cable through the Feedthrough Body (pre-installed on the enclosure at the factory) and insert the RJ-45 connector to the female connector inside the enclosure. 3. Install the Compression Nut and hand tighten until the cable resists slipping when gently pushed or pulled. Lightly wrench-tighten, being careful not to overtorque the Compression Nut. The unit with properly installed feedthrough appears as follows: NOTE - Removal of the RJ45 plug from the radio requires a tool such as a thin screwdriver, or opened paperclip. Care must be taken not to damage the Feedthrough Body or RJ45 plug. NOTE - The total combined length of the Ethernet cables between the radio and your network access device (hub/switch/pc) must not exceed 300 feet. 15

16 NOTE - Once mounted in a permanent location, additional weatherproofing tape (included) should be applied around the assembled fitting to further enhance durability. 5.3 Mounting Bracket and Tools The following figure shows all components of the mounting kit. The installation steps will be shown in the next section. Tools necessary for tightening bolts and nuts are: 10mm wrench for bolts to fasten the L-bracket to the radio enclosure 13mm wrench for nuts to tighten U-bolt nuts. 5.4 Unit Mounting The final installation step involves mounting your SkyWay radio to an outdoor mast. 16

17 Refer to the following diagram to perform the installation steps: Fasten the L-bracket on the back of the radio enclosure. The hole patterns are symmetric and you can rotate the enclosure by 90 degrees before installing the L- bracket for establishing the radio link with horizontal polarization. Using the step bracket and U-bolt, fasten the L-bracket to the mast. Azimuth alignment Rotate the enclosure assembly in the horizontal direction Vertical alignment - The L-bracket has a curved groove which can be used to tilt the enclosure up or down. Once the alignment is complete, tighten the bolts and nuts firmly. 17

18 5.5 Mounting of Separate Antennas Tower or mast mounting of the antenna should proceed according to the antenna manufacturer s guidelines. For interfacing to the Solectek radio, the following should be considered: To minimize loss, only short lengths of high quality, LMR-400 (or equivalent) RF coax cables should be used. For Base units, there are no requirements to connect specific radio ports to specific polarizations on the antenna. Solectek s MIMO system will auto-adjust to accommodate the chosen configuration. Weatherproofing Ethernet and/or antenna connections is essential. This process prevents water from entering the chassis or cables through the connectors. In order to provide an adequate seal, it is advisable to apply three wrappings: 1. electrical tape 2. sealant (such as the butyl mastic which is provided with the product) 3. electrical tape The first wrapping of tape should be a single layer, followed by a generous wrap of butyl mastic. Finally, apply two layers of electrical tape, completely covering the mastic layer. Wrap the last layer of tape such that water is always directed down and away from connections. 5.6 GPS Antenna Mounting An external GPS antenna is supplied in the package (base station only). It comes with a mounting bracket with hose clamps and cable. An example of antenna mounting is shown in the picture below: 18

19 For best results, mount the antenna above the radio and other structures so that it has least amount of obstruction to the sky. Some obstructions such as a pole and other items) may not be a problem. The GPS operation will not be interrupted if at least half of the sky is unobstructed. 6. WiFi Management Some ES700 radios have a built-in 2.4GHz Wifi module that can be used for accessing the user interface without Ethernet connection. First, you will need to connect a 2.4GHz omni directional antenna to the WiFi port (N-female connector at the bottom of the unit). The following is the picture of a 2.4GHz omni directional antenna (included): 19

20 NOTE - Make sure to connect the 2.4GHz omni directional antenna to the WiFi antenna port as shown in the figure below. A connectorized radio units will have the same N-type ports at the ends. These are for connections to external 5GHz antenna for data traffic between radios. Once the unit is powered up, you can take any wifi client device (smartphone, tablet, etc) and look for the following SSID SSID: OFFBAND-xxxxx The last five numbers represent the last five digits of the unit serial number so as to distinguish among multiple units in the vicinity. Once you are connected, open a browser and type in the defalt IP address to access the user interface. Default IP address: or The WiFi is enabled encryption enabled as a default factory configuration. To change the Wifi setting, navigate to Management -> WIFI MGT to see the following screen: 20

21 On this screen, you can enable/disable the WiFi user interface. If the interface is enabled, it is strongly recommended that encryption is enabled to keep the interface secure. 7. Ethernet Configuration Navigate to Configuration -> Ethernet Configuration to access the following screen. LAN /Default Gateway Configuration IP Address: IP address of the local unit. Subnet Mask: Subnet mask of the local unit. Default Gateway: Default gateway for the local unit. 21

22 NOTE On each screen, there are three buttons at the bottom Reset, Save and Save & Apply. Reset restores the values before you make any modifications. Save make the changes effective but does not write such changes to memory. Save & Apply writes the changes to memory. WARNING Make sure that you keep a record of the IP address information of the unit. 22

23 8. Wireless Configuration Navigate to Configuration -> Wireless Network to access the Wireless Configuration screen. Radio - Clicking the Disable button turns off the radio and you will not be able to communicate with the remote radio unit. Channel Spectrum Width Allows selection of the channel bandwidth (BW), in MHz, of the RF network. Allowable options are 20 MHz, 40 MHz and 80 MHz. 23

24 If maximizing throughput at shorter distance is of primary importance, then larger bandwidth of 40 and 80 MHz may be more appropriate. NOTE All radios units in your multipoint network must be configured with the same Bandwidth setting in order to have the link working properly. NOTE 80 MHz setting will adaptively fall back to 40 or 20MHz BW if the channel is not sufficiently clean for 80 MHz channel use. Likewise, a 40 MHz setting will drop to 20 MHz if the channel condition does not allow a 40 MHz operation. Channel Allows selection of frequency center for the 20MHz channel. If Channel Spectrum Width selection above is 20 MHz is used, this is the channel that is being used at all times. If Channel Spectrum Width selection is 40 or 80 MHz, this 20MHz channel becomes the fall back channel in adverse RF conditions. The following is a diagram of all available channels. Allowable channels of operation for outdoor links depend on the country/region. Allowed channels of operation in the US are: Channel 36, 40, 44, to 5.25 GHz Channels 149, 153, 157, 161, to 5.85 GHz US FCC version of ES700 is factory configured to operate in the above channels. International versions depend on the local regulations. 24

25 The Channel setting is available on the Base unit only. Client units will follow the setting of the Base unit. NOTE The channel usage in 5GHz frequency band varies according to the local regulatory environment in each country. Check with your government body for the appropriate channel use before your purchase. Solectek support various different channel plans to fit your needs. NOTE The FCC allows channels in the UNII-1 (5.15 to 5.25 GHz) and UNII-3 (5.725 to 5.85 GHz) bands for outdoor high-power use (the green channels in the above diagram). The ES700 operates in those channels for deployments in the US. Transmit Power Allows selection of the output power level of the local transmitter. The default value is Max (26dBm). Steps of 1 db decrement from the max level are available. Streams This specified the number of independent streams using a 2x2 MIMO radio. 2 streams will yield twice data rate as the 1-stream case, but the 1-stream operation provides a more robust link and may be useful in adverse RF conditions. The default is 2 streams. Distance (Mile) For the optimal performance of the link, the link distance should be entered here, rounded up to the nearest mile (1 mile = 1.6 km). This parameter is used to optimize the performance across long distance links, accounting for the time of flight for packet transport over the wireless channel. For a multipoint network with variable distances to clients, use the distance for the farthest client unit. Interface Configuration has two different sections, General Setup and Wireless Security. Mode In a multipoint network, only one unit is the base station and the rest are client units. The Base unit control the frequency channel and a few other parameters of operation. Client units follow the base for these parameters. Link ID This is the ID used by the multipoint network. If the ACL function is on (see below), the Link ID entered in all radio units must match for the link to be established. 25

26 NOTE - The Link ID should be changed from the default settings, and each multipoint network should use a unique Link ID so that only the right pair is associated in the event that there are multiple links in close proximity. NOTE Link ID can be up to 32 characters long, and consist of all alphanumerics, plus the following (at sign) - (dash). (period) (tick) _ (underscore). RF Network Name may not include spaces. Data Rate (Mbps) This determines the data rate or the capacity of the multipoint network. You can choose the Auto or one of the MCS values, which will use a fixed value of RF modulation and coding. The default value is Auto. The following is choices of MCS values and their corresponding modulation and coding schemes. MCS Index Modulation Coding 0 BPSK 1/2 1 QPSK 1/2 2 QPSK 3/ QAM 1/ QAM 3/ QAM 2/ QAM 3/ QAM 5/ QAM 3/ QAM 5/6 The AUTO setting above will enable the Adaptive Coding and Modulation (ACM) function in the network. This feature allows the system to determine the best TX modulation and MIMO settings based on current RF conditions. At power-up (or reset), the ACM function will begin operation at the most robust modulation settings (BPSK-1/2). If link conditions warrant, higher order settings will be tested and selected for use. The ACM function operates continuously, i.e. if RF link conditions change, then the modulation and MIMO settings will respond in order to maximize link capability without compromising reliability. 26

27 The system relies upon user traffic to determine the optimal modulation settings. When ACM is enabled, user traffic must be available in order to bring link performance up to its maximum capability. ACM is a feature that is enabled on a per-radio basis. It is not necessary for both radios to share the same state ACM enable/disable configuration. ACM seeks to optimize the TX modulation of the radio on which it has been enabled. Since RF conditions may not be the same on either side of the link, due to impairments such as interference, the system may not select the same TX modulation/mimo settings for each side. The RF power settings will not be adjusted by the ACM system. Access Control List This provides your base station to allow associations to only those client units that have the MAC addresses entered in the ACL if ACL is enabled here. Client MAC Enter the MAC addresses of authorized client units to be allowed association if the ACL is enabled. ATPC (Adaptive Transmit Power Control) This feature allows the multipoint network to maintain optimum level of Tx power, regardless of link distance or RF conditions. You can set the RSSI level you want to maintain the link at (typically around -50dBm) and the Tx power from the other side will automatically adjust its Tx power based on the feedback from the remote unit. ATPC s benefit is to insure the link quality is consistent overtime and guard against using excessive Tx power, especially for short links. Excessive Tx power is a big factor in radio colocation, so maintaining an optimum level will help achieve multiple radio installations at a crowded tower. Note that ATPC controls only the Tx power level of client units. Base stations are not affected by ATPC and will emit Tx power as set on the user interface. Navigate to Configuration -> Wireless Config and click on the Remote Power Control tab to see the following screen: 27

28 Here you can enable or disable TPC and then set the target RSS. Once the TPC is set, the local unit will communicate with the remote unit and request the remote unit s Tx power to be adjusted so that the local unit s RSS is the same as the value set on this screen. On a multipoint network, this feature is available on both Base unit to control the power of the client units. Tx power of base units cannot be controlled by clients units via ATPC. Base power is fixed only via base station GUI. The above screen is the Wireless Security section of the Interface Configuration screen. Encryption The user can enable or disable encryption here. The choices are No Encryption, WPA-PSK, WPA2-PSK, and WPA-PSK/WPA2-PSK Mixed Mode. The default is No Encryption. Cipher This specifies the cipher types. The choices are Auto, CCMP (AES), TKIP and CCMP (AES). Key This is the 128 bit key used for AES encryption. The key must match between the all radio units for the network to function properly if encryption is enabled. The key length has to be at least 8 characters. 28

29 9. System Properties This section deals with configuration of general system parameters that are not related to wireless or Ethernet functions. Navigate to Configuration -> System to see the following screen: Under the General Settings tab: Local Time indicates the current time on the radio unit s time clock. The time can be synchronized with the local host computer managing the radio by clicking Sync with local PC. System Name This is a one-word description that the user gives to the radio unit, e.g. branch_office_1. The System Name value is completely up to the user and has no effect on the wireless link operation. System Name can be up to 32 characters long, and consist of all alphanumerics, plus the following (at sign), - (dash),.(period), (tick), _ (underscore). Name may not include spaces. Timezone The user s own time zone can be specified in reference to UTC (Temps Universel Coordonné, Coordinated Universal Time). For example, the Pacific time zone in the US, is UTC- 8 or UTC-7 during the daylight savings time. Enable NTP Client An NTP (network time protocol) server can be used to set and synchronize the radio s clock. Clicking the box allows the user to enter the IP address of the NTP server below. 29

30 Provide server - Allows other network devices to be synchronized to this radio. NTP Server Candidates Once NTP is enabled above, the user can enter NTP server s IP address here. Clicking on the Logging tab will show the following screen: System log buffer size (kib) This defines the log buffer size. The default is 16KB. Remote Log Server The system log can be uploaded to a remote server. The user can specify the IP address of the remote log server here. External System Log Server Port Specify the port number to be used for connecting to the remote log server. Log Output Level This specify the types of log items to be uploaded to the remote server. 30

31 10. System Access Configuration Navigate to Configuration -> System to see the following screen: Password The user can change the system password here (the default value is admin). Confirmation Make sure that the new password is retyped correctly here. Web Server Mode The user can choose between the regular HTTP mode or secure HTTPS mode. The default value is HTTP. Port The port number to be used for web server. The default is 80. NOTE When you are using HTTPS mode on the radio unit, make sure to start with in the URL window of your browser. Just typing the IP address may not allow access to the radio GUI. CAUTION - It is strongly advised that the admin password be recorded and stored in a secure location. NOTE - Password & hint fields are case sensitive and no spaces are allowed. Password & hint should be 6-32 characters in length. To avoid a weak password warning when changing the password via Telnet, it is required that passwords contain a mix of uppercase letters, lowercase letters, numbers and symbols. 31

32 11. Antenna Alignment SkyWay Essence radio units contain several tools to aid with the antenna alignment process that is essential for client units. Audible Alignment: The radio produces an audible tone allowing antenna alignment without the need for additional monitoring hardware. CAUTION - A ping, or other network traffic is needed to ensure reliable operation of the alignment feature, in which case the Activity indicated will be in a green state. If no network traffic is detected, the Activity indicator will be in a red state. The pulsed tone will begin once an RF link has been established, regardless of quality. It is useful to reduce the RF modulation setting to its lowest value (BPSK) during the antenna alignment procedure to maximize the system s link capture envelope/angle. The audible repetition rate will increase as RSSI improves; a higher value will cause a faster rate. To assist with both coarse and fine tuning, the rate is NOT a simple function of RSSI value. Rather, the rate will continue to increase as long as adjustments deliver an improved RSSI. As soon as any degradation (alignment overshoot ) is detected, the rate quickly falls, regardless of the amount of reduction. Thus, the system is useful for both coarse and fine tuning of the antenna position. To ensure the system will deliver adequate link reliability, it is recommended that the operator verify the numerical RSSI following antenna alignment. The audible function is enabled for the first 30 minutes of operation following a power cycle. Regardless of whether the audible function is enabled or disabled, the unit will emit a short audible tone upon initial power-up. Navigate to Installation to display the following page: 32

33 Audio Alignment Enabled Clicking this box and clicking the Save button next to it enables the Audio Alignment mode for the specified duration upon every reboot The default setting for the audio alignment mode is ON. Interval The interval specifies how long (in minutes) the audio alignment mode will run before it stops. The default value of the interval is 30 minutes. Run Clicking the Run button next to the interval will start the audio alignment mode (the Run button will change to a Stop button at this point). Click the Stop button to stop the alignment mode once the alignment process is completed. Spectrum Analyzer Clicking the Launch button activates the spectrum analyzer mode, which will be described in the next section. NOTE The timer for the audio alignment interval will start to run once a link between the local and remote units is established. CAUTION If the audio alignment mode is left enabled, it will automatically restart upon reboot or power cycle of the radio for the interval specified on this screen. Make sure to disable once the antenna alignment process is completed. 33

34 12. Spectrum Analysis Once the radio has been mounted in its intended location, an embedded RF spectrum analysis tool can be used to survey the site and to aid with the initial channel selection process. Prior to enabling a spectrum analysis session, ensure that the units are mounted at the desired location and aligned in the general direction of the target radio. NOTE - If a noise and interference only analysis is desired, do not turn on the remote unit during the spectrum analysis, as the presence of the remote unit will affect the sweep data. NOTE - Enabling a spectrum sweep will disable RF traffic until the scanning process is completed. NOTE Fluctuations in RSSI values up to ±2 db should be expected. This should be considered normal behavior of the wireless channel. Click Installation -> Launch to access the Spectrum Analysis screen: 34

35 In the example screen shown above, all 20 MHz channels from 36 to 165 are scanned for RSSI and Noise Floor values. The user can assess which channel would be the cleanest one to be used from the values obtained here. Please keep in mind that for wider channel operations (40 or 80 MHz), you will need several blocks of 20 MHz channels to be relatively clean. Refer to the channel chart in Section 7 for frequency block uses. 35

36 13. Monitoring Operation Navigate to Status->Overview to monitor the current status of the system, as shown below. This screen is for status only. Navigate to the Configuration screens if setting changes are necessary. This screen periodically updates to the current status at every 2 seconds. There are several noteworthy items: System Section Up Time The elapsed time that the unit has been running since the last reboot or power cycle. This information is found in the upper right corner of the screen. 36

37 Serial Number This is the serial number of the radio system. The same serial number can be found on the label on the radio enclosure. Firmware Version The currently installed and operating firmware image version. GPS Location If GPS signal is properly received by the system, current GPS coordinates of the system is displayed here. Clicking on the GPS coordinates will lead to a map of the area with the system location pinpointed. This feature is available only for base stations. Wireless Section Link ID This is the current Link ID of the local unit. Make sure that the Link ID is the same for all radios in your multipoint network. It is recommended that the user assign a unique Link ID for each multipoint network so that there is no unintended RF association with another network. MAC This is the RF port MAC address of the radio system. Remote Device Information Section Here all of the client units that are currently associated in your multipoint network are shown. For a client unit, only the base station information is shown. For a base station, all of the client units are shown here. MAC-Address This is the RF MAC address of the remote unit in your multipoint network. 37

38 Signal This is the signal level strength measured by the local receiver. It is a measure of the RF transmission from the remote unit to the local unit derived from the 2 RF chains. Signal/Chains This is the received signal strength of each RF chain in a 2x2 radio (one received via vertical polarization and the other received via horizontal polarization of the antenna). Ideally, the two numbers should be similar, but practically there may be a small difference here, e.g. ±4dB. If there is a big discrepancy, there may be a problem with radio, antenna, cable, or, antenna alignment. The user can use this information for diagnostic purposes. Noise This is the noise level strength measured by the local receiver. It is a measure of the RF noise in the RF path from the remote unit to the local unit. Network Section MAC-Address This is the Ethernet MAC address of the local unit. This is used for identifying the radio in network management. Real Time Information Graphical display of traffic and RF parameters can be seen by navigating to Status -> Traffic or Status -> Wireless, as seen in the following screens: 38

39 Tx CCQ A useful value to monitor is Tx CCQ (Client Connection Quality). CCQ is a percentage measure of how the system is using the maximum available bandwidth. It is a weighted average value calculated per packet basis using the following formula: CCQ = Tmin / Treal where Tmin is the minimum time that a packet would take at the highest rate without retries and Treal is the time such a packet actually took in real life, taking into account retries and transmit rate. CCQ would be lowered if an adverse RF channel condition causes packet losses (thus retries) and the use of lower transmit rates. 14. Software Backup and Upgrade There may be new software releases from Solectek periodically posted on Solectek s support portal and available from Solectek Technical Support. 39

40 Upgrading the software will not affect the system configuration, but does require a short period of system downtime to complete the process. Navigate to Management -> Upgrade to see the following screen: Download Backup A backup copy of the current user configuration file can be downloaded by clicking Generate archive. The user can specify the file folder on your host computer to store the backup copy in. The backup copy will be stored in the tar file format. Reset to Defaults The user can restore the user configuration database to the factory setting by clicking the Perform reset button. CAUTION During the factory default operation, the radio will not be available for normal operation. Because of the changes in the radio configuration, the user will need to reconfigure the radio to the proper setting for your multipoint link before a link can be established. Restore Backup The user can download a previously saved configuration file into the radio and replace the current configuration database. Click Choose File to find the appropriate configuration file on your host computer and then click Upload archive to download the file into the radio memory. Firmware (current ver: Essence V.xxx) The user can upload a new firmware image to the radio from a host computer. Click Choose File to find the appropriate configuration file on your 40

41 host computer and then click Flash firmware to write the new image into the radio s flash memory. WARNING - Do not power down or unplug the unit during the upgrade/file upload process. Software image corruption may occur if power is disrupted during the flash write process. 15. System Reboot and Logout Navigate to Tools->Reboot to reboot the radio system. The following confirmation screen will appear to make sure that the reboot process was not initiated accidentally. Click on the Reboot button to reset/reboot. The reboot process will take approximately 30 seconds. Once the rebooting is finished, the browser refreshed the current page automatically. Navigate to Logout on the menu to log out of the GUI session. Similar to the reboot process above, a confirmation screen will appear as follows: 41

42 Click Perform Logout and the logout process is now completed. 16. System Log The System Log displays all major events that may be noteworthy for the system administrator for both monitoring and troubleshooting purposes. Clear Log Clicking the Clear Log button will erase all even log entries from the memory. 17. Diagnostic Tools For access to diagnostic tools, navigate to Tools -> Diagnostics menu to view the following: 42

43 The three tools above can be used to isolate an issue to the wireless link only, not involving other network elements such as switches and host computers. You can ping the remote unit from the unit you are accessing via the user interface. A default gateway and DNS server are needed to use these tools with a named target. Configuration -> Ethernet Configuration You can also navigate to Status -> ARP to view the ARP status for both base unit and client unit, as shown in the screen below: There are additional diagnostic tools to arrange automatic rebooting of the unit periodically or under certain circumstances. 43

44 Ping Watchdog If enabled, Ping Watchdog reboots the radio unit upon detecting that connection to a specified IP address is broken. You can specify IP address to Ping, Ping Interval (sec), Startup Delay (sec), and Failure Count to Reboot. The default condition is off. Auto Reboot In certain situations, the user may want to reboot the unit automatically. This can be done at a certain time of the day as specified in time or at a given specified time interval, e.g. every 12 hours. 44
