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.
2.1.3.4
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
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. You can also
configure any port to support a loop of private target devices.
