Replacing a power supply
• A small flat-blade or Phillips screwdriver (Brocade MLX-4 and Brocade 32-slot modules)
The power supplies are hot swappable, which means they can be removed and replaced while the device
is powered on and running. However, Brocade recommends that you disconnect the power supply from its
power source before removing and replacing the supply. The device can be running while a power supply
is being removed and replaced, but the power supply itself should not be connected to a power source.
Otherwise, you could be injured or the power supply or other parts of the device could be damaged.
The front panel of a power supply includes a handle that locks the power supply in the device. This handle
is a locking mechanism only and should not be used to lift and carry the power supply. You may sustain
physical injury or harm if you attempt to lift and carry a power supply using the locking handle.
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 Figure 155).
Pull the power supply out of the device.
