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.

2.1.3.4

Input Power LED (Green)

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.

Fibre Channel Ports

The SANbox2-16 switch has 16 Fibre Channel ports numbered 0–15 as shown in Figure 2-4. Each of these ports is served by a Small Form-Factor Pluggable (SFP) optical transceiver. The port LEDs are located to the right of 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.
