Perform the following steps in sequence:
1. Check Table 10 on page 21 for descriptions and explanations of LED
flashing sequences.
2. Reset the switch by pressing the recessed RESET button on the front panel.
3. If you were attempting to download software or manage the switch via the
RS-232 terminal Port, check that connections between the Terminal Port and
local terminal or PC are secure.
If you cannot access the switch’s software because of a faulty RS-232
Terminal Port connection, you can still manage the switch via Telnet or
SNMP until the problem is fixed.
4. Unplug the switch and then plug it in again. If present, you will also have
to disconnect and reconnect the RPS unit.
5. Download the latest software release. See the AT-8700XL Series Software
Reference for more information on how to obtain the latest software release.
