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. See "Power Supply Requirements" in the
Brocade
X7 Director Technical Specifications
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
to install the new
power supplies. Be sure to follow the 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.
See
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 the LED does not illuminate, the power supply has no incoming
power. Check if the power supply is properly seated in the backplane connector. Check the power source to the
power cord.
–
If the LED is flashing green, the power supply may be faulty.
For more information on LED operation, see
