Precautions specific to power supply assembly
Observe the following precautions when replacing the power supply assembly.
NOTE
Depending on the blade configuration of the device and the number of power supplies installed, the device may be able to
continue operating while replacing a power supply. Refer to "Power Supply Requirements" in
Brocade X6 Directors Technical
Specifications on page 225 for minimum power supplies required for AC low and high voltage line operation, redundancy in
case of power supply failure, and other specifications. If there is insufficient power, the device will start powering down blades
until the power demand can be met.
NOTE
A device with slots for eight port blades can have up to four power supplies installed. If you are adding additional power
supplies, you can use the procedures in this section under
Installing a power supply on page 187 to install the new power
supplies. Be sure to follow steps on those procedures to enable sending notifications if the additional power supplies should
fail.
NOTE
Make sure that captive screws securing power supply assemblies to chassis are tightened. If not, high pressure from fans
operation may unseat power supply assemblies from chassis connectors.
Refer to Safety precautions on page 21 for caution and danger notices related to installing power supplies.
Power supply assembly fault indicators
Use one of the following methods to determine if a power supply is faulty:
• Check the power supply status LED.
–
The LED may take up to 10 seconds to illuminate. If LED does not illuminate, the power supply has no incoming power.
Check if power supply is properly seated in backplane connector. Check power source to power cord.
– If LED is flashing green, the power supply may be faulty.
For more information on LED operation, refer to Interpreting power supply LEDs on page 110.
• Enter psShow . If status of power supply displays absent or faulty, check if power supply assembly is seated in chassis. If it is,
power supply could be faulty.
• Enter sensorShow to determine if a power supply is running above average temperatures of other installed power supplies.
• Enter errDump to display the system error log. Refer to the Brocade Fabric OS Message Reference for more information on
the messages in this log.
Refer to Using monitoring commands on page 115 and the Brocade Fabric OS Command Reference for output examples and
additional information on Fabric OS commands.
For more information about error messages, refer to the Brocade Fabric OS Message Reference .
