Verifying proper operation
To verify the proper operation of the power supply after power on, you can observe the LEDs on the
power supply.
After the Brocade device powers on, you can observe the LEDs on the front of the device to verify that
it initialized successfully. There is a single LED on the power supply which should be steady green
when the power supply is receiving power and under normal operation.Table 1 outlines the LEDs, the
desired state of each LED, possible abnormal states of each LED, and what to do if an LED indicates
an abnormal state.
To verify proper operation, complete the following steps.
1. Verify that the power supply's LED is steady green on the back of the device.
2. Verify that the power supply was placed in power supply bay #1 and operational by observing a
steady green LED lighting up "P1" on the front of the device.
