Chapter 3 Installing a Cisco 7500 Series Router

Installing the Cisco 7513, Cisco 7513-MX, and Cisco 7576

Caution To maintain agency compliance requirements and meet EMI emissions standards in the Cisco 7513,

Cisco 7513-MX, and Cisco 7576 chassis with a single power supply, the power supply blank must remain

in the empty power supply bay. Do not remove this blank from the chassis except to install a second

power supply.

Figure 3-19 Power Supply Blank (Cisco 7513, Cisco 7513-MX, and Cisco 7576)

If you are installing both power supplies, repeat Step 1 through Step 7 for the second power supply. To

prevent system problems, do not mix AC-input and DC-input power supplies in the same chassis.

Connecting Power to Cisco 7513, Cisco 7513-MX, and Cisco 7576 DC-Input

Power Supplies

This procedure assumes you have already installed the power supplies using the procedure in the

“Installing Cisco 7513, Cisco 7513-MX, and Cisco 7576 Power Supplies” section on page 3-27. The

power supplies rest on the floor of the chassis under the card cage. This procedure requires an 8-mm nut

driver and 8-AWG cable for power supply connections. The DC-input cable must be routed through

conduit from your power source to the power supply.

Note For the Cisco 7513, Cisco 7513-MX, and Cisco 7576, you provide a conduit through which you must

route the DC-input power cable. If cables from other equipment are in front of the bay, move them aside

and temporarily secure them with cable ties. You must disconnect the conduit from the conduit bracket

before you can remove a power supply from the chassis. Route and attach the conduit to make each

power supply accessible for replacement and maintenance.

Warning

Before performing anyofthe following procedures,ensure that power is removedfromthe DCcircuit.

To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC

circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit

breaker in the OFF position.
