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 5-1for 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.
