Removing a power supply and fan assembly
Complete the following steps to remove a combined power supply and fan assembly from a Brocade
6505.
1. If the Brocade 6505 has only one power supply and fan assembly, then the switch must be powered
off prior to replacing the assembly. If the Brocade 6505 has two power supply and fan assemblies
installed, verify that the other power supply and fan assembly (the one not being replaced) has
been powered on for at least four seconds and has a steady green LED.
2. If the Brocade 6505 has two power supply and fan assemblies, skip to step 3. If the Brocade 6505
has only one power supply and fan assembly, enter the sysShutDown command before powering
off the assembly to maintain the reliability of the system.
3. Power off the assembly to be replaced by switching the AC power switch to the O symbol.
If the Brocade 6505 has two power supply and fan assemblies,the fans in the second power supply
will automatically switch to high speed to maintain adequate cooling.
4. Unplug the power cord from the power supply and fan assembly that is being replaced.
5. Using a Phillips screwdriver, unscrew the captive screw.
6. Remove the power supply and fan assembly from the chassis by pulling the handle out and away
from the chassis.
7. Note the part number on the assembly just removed.
