Performing the following tasks will eliminate the most common faults.
1. Make sure the power cord is securely connected.
2. Check that the power supply voltage is stable.
3. Check that the correct data cables are being used and that their connections
are secure.
4. Make sure that other network devices are working properly.
5. Use the SHOW INSTALL command to check that the latest software release
is loaded. See the AT-8700XL Series Software Reference for more information
about obtaining the latest software release.
6. If the switch is malfunctioning, reboot it by pressing the recessed Reset
button or entering the command RESTART REBOOT. Alternatively, power
OFF and ON the switch by disconnecting and reconnecting the main power
supply (including, if connected, the RPS power).
