Chapter 5 Removal and Replacement Procedures
Removing and Replacing the Power Supply
Step 2
Turn the power switch to the Off (0) position on the power supply you are removing (
Figure 5-40
).
Turning the power switch off also disengages a pawl that unlocks the power supply from the chassis.

DC-Input Front Panel for 4000-W DC-Input Power Supply
Note
Figure 5-40
shows PWR-4000-DC with an outer terminal block cover; an earlier version of this power
supply does not have an outer terminal block cover. To order a retrofit kit use part number
CVR-4000DC-TERM=.
Step 3
Remove the two A4 screws securing the outer terminal block cover, and remove the cover from the power
supply (
Figure 5-40
).
Step 4
Cut any cable tie-wraps being careful not to cut the DC-input wires.
Note
The 4000 W DC-input power supply provides voltages of 2700 W or 4000 W for single and redundant
configurations. Some configurations require cable tie-wraps. For more information, refer to
Installing a
PWR-4000-DC Power Supply in a Cisco 7613 Router, page 5-91
.
Step 5
Remove the two screws securing the left inner terminal block cover and one screw securing the right
inner terminal block cover. Remove both inner terminal block covers.
