Replacing or Installing Modules, Fan Trays, and Power Supplies
• There are one or two AC power sources available. If using n+n redundancy, there must be two power
Step 1 Open the packaging for the new 3-kW AC power supply and inspect the module for damage.
If the module is damaged, contact the Technical Assistance Center (TAC).
Step 2 If you are installing the module in an empty slot, remove the blank filler plate that is already in that slot. Unscrew its
captive screws and pull it out of the slot. If you are using the combined power mode or n+1 redundancy, you can use any
power supply slot in the chassis. If you are using n+n redundancy mode, you must be sure that you are inserting the power
supply in a slot that is used for the desired power supply (the power supplies in slots 1 through 5 must be connected to
one power source and the power supplies in slots 6 through 10 must be connected to the other power source). Go to Step
4.
Step 3
If you are replacing a power supply that is currently in the chassis, remove the existing module from the chassis by
following these steps:
a) Disconnect the power cable from the power supply and verify that the output and input LEDs turn off.
b) Slide the middle of the ejector lever down to the end of the lever and rotate the lever up so that its other end no longer
holds onto the chassis. See the following figure.
The power supply unlocks from the chassis and moves out slightly.
1 Rotate the cable retention clip away from the power
cable plug.
2 Pull the power cable plug out of the receptacle.
3 Slide and hold the middle handle on the ejector lever
toward the end of the lever.
c) Pull on the lever to move the power supply about 2 inches (5 cm) out of the slot.
d) Place one hand on the front of the power supply and your other hand under the power supply to support its weight.
e) Pull the module out of the slot and place it on an antistatic surface or inside an antistatic bag.
Step 4 To install the new power supply, follow these steps:
a) Ensure that the power supply is not connected to an AC power source. If it is connected to a power source, remove
the power cable from the power supply and wait at least five seconds before doing the next step.
sources available. Otherwise, only one power source is required.

4 Rotate the ejector lever away from the module.
5 Pull on the ejector lever to slide the power supply
partially (2 inches [5 cm]) out of the chassis. Hold
the front of the power supply and pull it all the way
out of the chassis.
