14 1200-Watt AC-Input Power Supply Replacement Instructions
Removing and Replacing a Power Supply
Caution
To maintain agency compliance requirements and meet EMI emissions standards in a
Cisco 7513 chassis with a single power supply, the power supply blank must remain in the power
supply bay adjacent to the power supply. (See Figure 7.) Do not remove this blank from the chassis
unless you do so to install a redundant power supply. To prevent system problems, do not mix
AC-input and DC-input power supplies in the same chassis.

Replacing a Power Supply
Follow these steps to replace the power supply:
Step 1
Hold the supply as shown in Figure 6 and slide it into the power supply bay. Push the supply
all the way into the chassis until the sides are flush against the chassis frame. To prevent
damaging the backplane connector, do not jam the power supply into the bay.
Step 2
Use the large slotted screwdriver to tighten the captive screw that secures the power supply
to the chassis frame. (See Figure 5.)
Step 3
Reconnect the power cable to the power receptacle on the power supply.
Step 4
After the AC power cable is reconnected, reconnect the power cable at the power source
but do not turn ON power to the new power supply.
Step 5
If you are replacing both power supplies, repeat Steps 1 through 3 for the second power
supply.
This completes the power supply replacement procedure.
Proceed to the following section “Checking the Installation” to apply power and check the
installation.
