Note The Cisco 7513 and the Cisco 7576 routers are shipped with the power supplies removed. Each chassis comes with one power supply as standard equipment; a second power supply is optional equipment. The power supplies rest on the floor of the chassis under the card cage assembly.

This procedure applies to AC-input and DC-input power supplies, with differences clearly noted. Do not mix AC-input and DC-input power supplies in the same chassis. Install the first power supply in the lower power supply bay and the second, if any, in the upper bay. In systems with dual power supplies and separate available power sources, connect each power supply to separate input lines—the second power source will likely be available during a failure.

Step 1 For AC-input power supplies, confirm that the power on the power supply is off.

For DC-input power supplies, turn off the circuit breaker to which you will connect power, and tape the breaker switch to the off position.

Step 2 Hold the power supply by the handle and place your other hand underneath it.

Caution Use two hands to remove and install power supplies.

Step 3 Place the power supply inside the bay, and align it to go straight into the bay.

Step 4 Push the power supply back into the bay until its front panel is flush with the chassis rear panel.

Step 5 Use a screwdriver to tighten the captive installation screw on the top of the power supply.

For AC-input power supplies, proceed to the “Connect AC-Input Power Supply” section on page 12. For DC-input power supplies, proceed to the “Connect DC-Input Power Supply” section on page 13.
