SM Does Not Register to an AP
To troubleshoot a SM failing to register to an AP, perform the following steps.
Procedure 31 Troubleshooting SM failing to register to an AP
1 Access the Radio tab in the Configuration page of the SM.
2 Note the Color Code of the SM.
3 Access the Radio tab in the Configuration page of the AP.
4 Verify that the Color Code of the AP matches that of the SM.
5 Note the Radio Frequency Carrier of the AP.
6 Verify that the value of the RF Frequency Carrier of the AP is selected in the Custom
Radio Frequency Scan Selection List parameter in the SM.
7 In the AP, verify that the Max Range parameter is set to a distance slightly greater than
the distance between the AP and the furthest SM that must register to this AP.
8 Verify that no obstruction significantly penetrates the Fresnel zone of the attempted
link.
9 Access the General Status tab in the Home page of each module.
10 Remove the bottom cover of the SM to expose the LEDs.
11 Power cycle the SM.
RESULT:
Approximately 25 seconds after the power cycle, the green LED labeled LNK
must light to indicate that the link has been established. If the orange LED labeled SYN
is lit instead, then the SM is in Alignment mode because the SM failed to establish the
link.
12 If the AP is configured to require authentication, ensure proper configuration of RADIUS
or Pre-shared AP key.
13 In this latter case and if the SM has encountered no customer-inflicted damage, then
request an RMA for the SM.
