Determining the status of a power supply

Complete the following steps to determine the status of a power supply.

1. Check the LED indicator on the power supply (see the following figure). The LED patterns may 

temporarily change during POST and other diagnostic tests; for information about how to 
interpret the LED patterns, refer to 

. The Brocade DCX 8510-4 has two power supplies. 

Be sure to check each module.

2. Check the power supply status by entering psShow.

The power supply status displays OK, Absent, or Faulty. If a power supply displays absent or 
faulty, contact the Brocade DCX 8510-4 supplier to order replacement parts. Both physically 
absent or faulty could also be the result of the power supply not being properly seated or being 
turned off.
