Replacing a power supply
To replace a power supply, have the following items available:
A new power supply (AC or DC), which you can order from Brocade
A small flat-blade or Phillips screwdriver (Brocade MLXe Series-4 and Brocade 32-slot modules)
CAUTION
Remove the power cord from a power supply before you install it in or remove it from the device. Otherwise, the power supply
or the device could be damaged as a result. (The device can be running while a power supply is being installed or removed, but
the power supply itself should not be connected to a power source.)
CAUTION
To prevent damage to the chassis and components, never attempt to lift the chassis using the fan or power supply handles.
These handles were not designed to support the weight of the chassis.
1. Disconnect the power supply from the power source.
2. Disconnect the power cables from the power supply.
3. Remove the power supply from the device:
For a 4-slot device: Use the screwdriver to loosen the two screws on both sides of the power supply faceplate. Then pull
the ejectors forward until the power supply disconnects from the backplane.
For an 8-slot or 16-slot device: Pull up on the plunger on the faceplate and pull the handle toward you until the power
supply is released.
For a 32-slot device: Make sure the captured screw underneath the latch handle on the power supply faceplate is loose.
Pull down on the latch handle and curl your fingers over the handle. Pull the handle straight out toward you to unlock the
power supply (see the following figure).
Pull the power supply out of the device.
