Interpreting switch LEDs
4
Table 6
identifies how the system status LEDs behave when certain conditions are met. During
POST, all LEDs are lit briefly. Certain error conditions will illuminate the amber Fault LED, for
example, if temperatures exceed normal parameters. In such circumstances, power will shut off.
Normal-operation LEDs
After POST is complete, and if no diagnostics are being run, LEDs are used to monitor the state and
health of the Brocade 6545 16 Gbps FC Switch Module. LED functionality relies on green or amber
light that is shown as steady, flashing, or flickering, depending on the Switch Module operating
mode. When LEDs are off, there is no light or signal carrier (for example, no module or cable) for
the media interface. The green and amber switch LEDs are shown as steady or flashing depending
on whether the Switch Module has power, is up and running, or results in an error.
The LED indications are described in the following tables:
•
Table 7
lists LED activity for the FC ports. Each port LEDs are bi-colored (green and amber).
•
Table 8
lists LED activity for the Switch Module status and internal components.
