Installing a redundant power supply

DRAFT: BROCADE CONFIDENTIAL
1. If necessary, before installing a power supply, remove the power supply locking screw located
in the center rear of the device, and remove the cover plate (illustrated in Figure 22 on an AC
device). If you are replacing an existing power supply, pull the old power supply gently out of the
device, using the handle.

2. If the empty power supply bay has a cover plate, unlock it by pressing inward on the two latches
at the edges of the cover plate (refer to Figure 22 ), then remove the plate.
3. Remove the new power supply from the packaging.
4. Prepare the positive, negative, and ground wires by stripping about 1/4 in. of insulation off the
end of each one. (Use 10 AWG wire.)
5. Loosen the three screws used to hold the wires in the connectors, as shown in Figure 25 .
NOTE
The handle on the front panel of the power supply may block access to the negative and
positive terminal screws. You may need to temporarily remove the receptacle for the positive
and negative terminals if you can not access the screws used to hold the wires in the
connectors.
6. With one hand, grasp the handle on the front panel of the power supply. Use your other hand
to support the underside of the power supply while you insert it in the empty slot. Press gently
so that the connectors on the back of the supply are fully engaged with the pins on the power
backplane. Refer to
Figure 23 .
CAUTION
Make sure you insert the power supply right-side up. It is possible to insert the supply upside
down, although the supply will not engage with the power backplane. The power supply is
right-side up when the power connector is on the left and the fan vent is on the right.
