2.1.2.1

Over Temperature LED (Amber)

The Over Temperature LED provides status information about the air temperature inside the switch. This LED illuminates to indicate that the switch logic circuitry is overheating. Refer to Section 5 Diagnostics/Troubleshooting for information about troubleshooting over temperature conditions.

2.1.2.2

Fan Fail LED (Amber)

The Fan Fail LED indicates operational status of the fan. This LED illuminates if the speed of the fan falls below the normal range. If the Fan Fail LED illuminates, isolate the switch from the fabric, unplug the switch from the AC power source, and contact your authorized maintenance provider.

2.1.2.3

Heartbeat LED (Amber)

The Heartbeat LED indicates the status of the internal switch processor and the results of the Power On Self Test (POST). Following a normal power-up, the Heartbeat LED blinks about once per second to indicate that the switch passed the POST and that the internal switch processor is running. In maintenance mode, the Heartbeat LED illuminates continuously. Refer to “Heartbeat LED Blink Patterns” on page 5-2for more information about Heartbeat LED blink patterns.
