Troubleshooting
This section provides information on how to detect and resolve problems with NSMs.
Performing the following tasks will eliminate the most common faults.
1. Check that the NSM is correctly installed. See the Network Service Module
Installation and Safety Guide for a step by step guide to installing NSMs.
2. Make sure the power cord is securely connected to the switch or router and
the power outlet.
3. Check that the power supply voltage to the switch or router is stable.
4. Check that the correct data cables are being used and that their connections
are secure.
5. Make sure that other network devices are working properly.
6. Use the show install command to check that the latest software release is
loaded. The AlliedWare
®
Operating System Software Reference for your switch
or router has more information about obtaining and installing the latest
software release.
7. If the switch or router is malfunctioning, reboot it by pressing the recessed
Reset button or entering the command restart reboot. Alternatively, power
off and on the switch or router by disconnecting and reconnecting the main
power supply and, if connected, the RPS power.
