Replacing or Installing Modules, Fan Trays, and Power Supplies
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 by unscrewing
its captive screw and pulling it out of the slot. If you are using the combined power mode (no power redundancy) or
power-supply (n+1) redundancy, you can use any power supply slot in the chassis. If you are using input-source (grid
or n+n) redundancy mode, you must be sure that you are inserting the power supply in a slot used for the desired power
supply (the power supplies in slots 1 through 4 must be connected to one power source and the power supplies in slots
5 through 8 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 off of 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.

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.
