Removing the Old Card Cage and Backplane Assembly
Caution To maintain agency compliance requirements and meet electromagnetic interference
(EMI) emissions standards in a Cisco 7513 or Cisco 7576 chassis with a single power supply, the
power supply blank must remain in the power supply bay adjacent to the power supply. (See
Figure 10.) Replacethis blank in the chassis after you replace the card cage assembly. To prevent
system problems, do not mix AC-input and DC-input power supplies in the same chassis.

Step 5 Repeat Step 1 through Step4 for a second power supply, if one is installed.
Repeat Step 3 and Step4 for the power supply blank, if one is present.
This completes the power supply removal procedure.
Removing the Old Card Cage and Backplane Assembly
The card cage and backplane consist of one assembly that can be removedand replaced as required.
There are no wires, harnesses, or connectors. The assembly slides into and out of the chassis and
attaches to the chassis frame with four slotted captive screws. (See Figure11.)
For this procedure, you need one large flat-blade screwdriver, an antistatic bag for each removed
processor module, or several antistatic mats or pieces of antistatic foam.
Timesaver Before you can remove the card cage and backplane assembly, you must remove all
processor modules and both powersupplies. Plan this procedure so that you can minimize its effects
on your system.
