To turn on power to the switch, connect the power cable to the switch and then to the
wall outlet, and turn the on/off switch to the On position.
After turning on power to the switch, it performs a Power On Self-Test (POST).
During the POST, all ports are temporarily disabled, the packet LED is off, the Power
LED is on, and the DIAG LED (AT-9108, AT-8518) or MGMT LED (AT-8525,
AT-8550) flashes.
If the switch passes the POST, the DIAG LED or MGMT LED blinks at a different
rate. If the switch fails the POST, the DIAG LED or MGMT LED shows a solid
yellow light.
For more information on the LED indications, refer to Chapt er1, Tables 1-2, 1-3
and 1-4.
