Chapter 5 Removal and Replacement Procedures
Removing and Replacing the Power Supply
Step 4
Cisco 7603 router, Cisco 7609 router, and Cisco 7613 router—Grasp the power supply handle with one
hand. Place your other hand underneath the power supply (see
Figure 5-5
for Cisco 7603 router and
Figure 5-6
for Cisco 7609 and Cisco 7613 routers). Slide the power supply into the power supply bay.
Make sure that the power supply is fully seated in the bay.
Cisco 7604, Cisco 7606, Cisco 7606-S routers—Grasp both power supply handles, as shown in
Figure 5-7
. Slide the power supply into the power supply bay. Make sure that the power supply is fully
seated in the bay.
Note
If you are installing a PWR-2700-AC 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 5-112
.
Step 5
Securely tighten the power supply captive installation screws. (See
Figure 5-2
for the Cisco 7603 router,
Figure 5-3
for the Cisco 7604 router, the Cisco 7606 router, and the Cisco 7606-S router, and
Figure 5-4
for the Cisco 7609 and the Cisco 7613 routers.)
Warning
Power supply captive installation screws must be tight to ensure protective grounding continuity.
Step 6
Plug the power cord into the power supply or PEM.
Step 7
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 8
Turn the switch on the power supply or PEM to the On (|) position.
Step 9
Verify power supply operation by checking that the power supply LEDs are in the following states:
•
INPUT OK LED is green
•
FAN OK LED is green
•
OUTPUT FAIL LED is not lit
If the LEDs indicate a power problem, see the
“Identifying Startup Problems” section on page 4-2
for
troubleshooting information.
