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 5-1 for more information about Heartbeat LED blink patterns.
2.2.2.4
Input Power LED (Green)
The Input Power LED indicates the voltage status at the switch logic circuitry. This
LED illuminates when the switch logic circuitry is receiving the proper DC
voltages.

Fibre Channel Ports
Each I/O blade has eight Fibre Channel ports that are interconnected with all other
I/O blades through the backplane. Fibre Channel ports are numbered according to
the slot in which the I/O blade resides. Each port is served by a Small Form-Factor
Pluggable (SFP) transceiver. A Port Status LED, located to the left of each port as
shown in Figure 2-5, provides port login and activity status information. Port
modes configure the ports to communicate with public devices and other
switches.
