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.

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 

 for more information about Heartbeat LED blink patterns.

The Input Power LED indicates the voltage status at the switch logic circuitry. 
During normal operation, this LED illuminates to indicate that the switch logic 
circuitry is receiving the proper DC voltages.

The SANbox2-8c switch has 8 Fibre Channel ports numbered 0–7 as shown in 

. Each of these ports is served by a Small Form-Factor Pluggable (SFP) 

optical transceiver. The port LEDs are located above their respective ports and 
provide port login and activity status information. The ports self discover the 
proper mode when connected to public devices and other switches.
