Removing and Replacing Field-Replaceable Units
Turn off power to the branch circuit that feeds power to the PEM that you are
Step 2
replacing.
At the terminal block on the PEM that you turned off, use a voltmeter to verify
Step 3
that there is no power present.
Use a screwdriver to loosen the screws on the PEM terminal block and remove the
Step 4
wires. Be sure to disconnect the ground (bottom wire) last.
Loosen the captive screws on the DC PEM you are removing and pull the PEM
Step 5
from the chassis using the handle on the faceplate
Figure 3-5
Insert the new DC PEM all the way into the power bay to ensure a secure
Step 6
connection to the midplane. Tighten the captive screws.
If you do not install a new PEM immediately, cover the empty power bay with a
Step 7
blank faceplate.
