Chapter 5 Removal and Replacement Procedures
Removing and Replacing the Power Supply
Note
When using a PWR-2700-DC/4 power supply in a Cisco 7604 router, you must always connect
the PWR-2700-DC/4 power supply ground.
Note
For redundant power supplies, you must connect the PWR-2700-DC/4 power supply ground for
both power supplies.
a.
Install the PWR-2700-DC/4 power supply ground as described in this procedure.
b.
If you intend to use an additional system (earth ground), ensure that the system 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.
Step 3
Verify that power is off to the DC circuit connected to the power supply you are installing.
Grasp both power supply handles, as shown in
Figure 5-52
. Slide the power supply into the power supply
bay. Make sure that the power supply is fully seated in the bay.
