Replacing or Installing Modules, Fan Trays, and Power Supplies
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 Verify that the OK LED turns off.
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.
b) Hold the front of the module with one hand and place your other hand under the module to support its weight.
c) Rotate the power supply 90 degrees so that the power receptacle is positioned on the lower front side. That way the
back of the power supply is oriented to slide into the open power supply slot.
d) Slide the guide bracket that is located on the top of the power supply into the track at the top of the power supply
slot. Slide the power supply all the way into the slot.
The front of the power supply is about 0.25 inches (0.6 cm) outside the chassis.
e) Slide the handle on the middle of the power supply ejector handle about 0.25 inches (0.6 cm) and rotate the lever
away from the front of the power supply. Do this while pushing the power supply all the way into the chassis. See
the following figure.
4 Slide and hold the middle handle on the ejector lever toward the end
of the lever.
5 Rotate the ejector lever away from the module.
6 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.
