Replacing the DC PEM
Step 1 Verify that the power switch on the replacement DC PEM is in the off position (see Figure 5-6).
Tip It is a good idea to tape the power switch in the off ( O ) position to keep from accidentally
turning the PEM on.
Step 2 Position the replacement DC PEM in the power bay and push it forward, verifying that it goes all the
way in and makes a secure connection with the backplane. Tighten the captive screws (see
Figure 5-9).
