12 1200-Watt AC-Input Power Supply Replacement Instructions

This procedure is not for new system installation; perform this procedure only if you have

already connected the system to network interfaces and performed the first-time startup procedures
described in the Cisco 7500 Series Installation and Configuration Guide.

Although it is not necessary to turn off both power supplies to remove one of two power supplies,

you must turn off the power to the power supply you plan to remove. When the power is on with one of two
power supplies removed, high current is exposed on the power connector inside the chassis. If you have only
one power supply, you must turn off the power to this power supply.

Removing a Power Supply

To remove a power supply, follow these steps:

Turn off (O) the system power switch on the power supply you plan to remove.

If possible, turn off the circuit breaker to which the system is connected and tape the
breaker switch in the off position.

This unit might have more than one power cord. To reduce the risk of electric shock, disconnect

the two power supply cords before servicing the unit. (To see translated versions of this warning, see page 8.)

Disconnect the power cable from the power receptacle of the power supply to be replaced.

Use the large slotted screwdriver to loosen the captive screw that secures the power
supply to the chassis frame. (See Figure 5.) Only loosen the captive screw of the power
supply you are removing.

Grasp the power supply handle and pull the power supply approximately halfway out of
the bay. With your other hand under the power supply, pull it completely out of the bay.
(See Figure 6.)
