Removing a Power Supply
To remove a power supply, complete the following steps:
1. Before removing a power supply assembly, verify whether you can remove the power supply and leave the chassis
operating (hot-swap replacement) or whether you must power down the chassis (cold-swap replacement).
NOTE
Depending on the blade configuration of the chassis and the number of power supplies installed, the chassis
may be able to continue operating while replacing a power supply. See "Power Supply Specifications" and
"Power Supply Requirements" in Brocade X7 Director Technical Specifications for the minimum power
supplies required for low and high voltage line operation, redundancy in case of power supply failure, and
other specifications. If there is insufficient power, the chassis will power down blades until the power demand
can be met.
2. Perform one of the following steps:
•
If you need to power down the chassis to remove a power supply, enter the sysShutdown command. See
Powering Down the Chassis for detailed procedures. When the chassis completes shut-down, remove power cords
from all power supply assemblies.
NOTE
To remove a power cord from an HVAC/HVDC power supply, you must remove the power cord retainer
cover, if attached under the power cord connector, and then unlatch the power cord release latch located
under the power cord connector.
•
If you can leave the chassis in operation and replace a power supply, unplug the power cord from the power supply
assembly that you are replacing.
NOTE
Be sure to replace the power supply as soon as possible.
3. Loosen the captive screw on the right side of the power supply assembly until the screw releases from the chassis.
The captive screw is located just below the airflow label on the right side of the power supply assembly. If necessary,
use a Phillips screwdriver.
