Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Note If you are installing a PWR-2700-DC power supply in a Cisco 7606 router, you must remove any
preinstalled PEMs. You must also install a blank PEM filler plate for each power supply you are
installing. See Removing and Replacing the PEM, page 5-106.

Step 1 Ensure that the system (earth) ground connection has been made. For ground connection installation
instructions, see the “System Ground Connection” section on page 3-19.
Step 2 Remove the plastic bag attached to the front panel and put aside. This bag contains two plastic terminal
block barriers, two cable ties, and two cable holder covers.
