SU Alignment Using LEDs

The LED RSSI indicators on the bottom of the radio provide a handy alignment tool. If all four LEDs are lit, the unit is receiving –64 dBm or stronger. If no LEDs are lit, there is not sufficient signal strength to establish a wireless link.

Lit LEDs

Signal Strength

0 LED

-86 dBm or weaker

1 LED

-76 to -85 dBm

2 LED

-69 to -75 dBm

3 LED

-66 to -70 dBm

4 LED

-65 dBm and stronger

Note: RSSI tool (telnet or LEDs) will show all RF energy on a given freq. i.e. – a nearby SU on the same freq. passing traffic may give the appearance of a strong signal from your AP when in fact it is not and cause a misalignment.

Link Management Commands

Once the radios are properly aligned for maximum RSSI, ensure the SU’s default Opmode is “ON” and that all configuration parameters are correct.

Reboot the SU. Once the SU enters Opmode “ON” the authentication process will begin, and the two radios will begin to associate. From the AP side, there are several basic diagnostics commands, such as su ping, su info, and su testrflink, which can check if a reliable RF link has been established. It may take one minute or more for the association process to complete. This process may take longer if there are many SUs in the sector.

If all tests show favorable results, the wireless link will automatically begin passing Ethernet traffic between the radios.

In establishing and diagnosing the quality of the link between AP and SU(s), there are a few commands that are especially useful. All of these commands are performed at the AP. A summary of these commands follows:

su

Displays the status of all SUs in the AP’s SUDB. SUs in the SUDB will appear by SU ID, and will be classified into one of the following status categories: Associated, Associating, or OFF. All associated SUs will be indicated.

Example: #> su [Priority] 1

[0]1

[Associating] [Power Off] 17 Success.

su ping <suid>

AP will send 10 RF pings to the designated SU ID. The response from each ping will indicate latency (in micro-seconds) and the received signal strength (RSSI) from the SU for each of the 10 pings. Note this command will also tell you the distance from the AP to the SU.

Example: #> su ping 1 [#Begin]
