Removing and Installing PEMs
Installing the AC-Input PEM
To install an AC-input PEM, follow these steps:
Step 1
Ensure that the system (earth) ground connection has been made.
For ground connection instructions, see the
“Establishing the System Ground” section on page 3-52
.
Step 2
If necessary, remove the blank PEM filler plate (Cisco part number 800-16719-01) from the chassis PEM
bay opening by loosening the captive installation screws. Retain the blank PEM filler plate for future use.
Step 3
Grasp the PEM with one hand. Place your other hand underneath the PEM, as shown in
Figure 4-58
.
Slide the PEM into the PEM bay. Make sure that the PEM is fully seated in the bay.
Step 4
Tighten the PEM captive installation screws. (See
Figure 4-57
.)
Step 5
Plug the power cord into the PEM.
Note
See Appendix A for a list of supported AC power cords.
Step 6
Connect the other end of the power cord to an AC-input power source.
Caution
In a system with dual power supplies, connect each power supply to a separate input source. In case
of a power source failure, the second source will most likely still be available.
Step 7
Turn the power switch to the on (|) position on the PEM.
Removing the DC-Input PEM
Warning
Before performing any of the following procedures, ensure that power is removed from the
DC circuit.
