Step 2
Turn off power to the branch circuit that feeds power to the PEM that you are
replacing.
Step 3
At the terminal block on the PEM that you turned off, use a voltmeter to verify
that there is no power present.
Step 4
Use a screwdriver to loosen the screws on the PEM terminal block and remove the
wires. Be sure to disconnect the ground (bottom wire) last.
Step 5
Loosen the captive screws on the DC PEM you are removing and pull the PEM
from the chassis using the handle on the faceplate (
Figure 3-5
).

Step 6
Insert the new DC PEM all the way into the power bay to ensure a secure
connection to the midplane. Tighten the captive screws.
Step 7
If you do not install a new PEM immediately, cover the empty power bay with a
blank faceplate.
