Chapter 3 Installing a Cisco 7500 Series Router

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

Warning

Before working on a chassis or working near power supplies, unplug the power cord on AC units or

disconnect the power at the circuit breaker on DC units.

Warning

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.

Use this procedure to connect power to DC-input power supplies in the Cisco 7513, Cisco 7513-MX,

and Cisco 7576:

Step 1 Turn off (O) the system power switch on the power supply you want to attach DC-input cable.

Step 2 Remove the 8-mm screws on the terminal block cover so the cover is free of the terminal block.

Figure 3-20 Removing the Terminal Block Cover (Cisco 7513, Cisco 7513-MX, and Cisco 7576)

Step 3

Lift and remove the cover.

Warning

When stranded wiring is required, use approved wiring terminations, such as closed-loop or

spade-type with upturned lugs. These terminations should be the appropriate size for the wires and

should clamp both the insulation and the conductor.

Step 4 Route the DC-input power cable through the conduit from your power source, through the conduit

bracket on the power supply, and make a sufficient length of wire available to attach to the three terminal

block connections.

Step 5 Attach and tighten the conduit to the conduit bracket. How this conduit is attached depends on your site;

its attachment is beyond the scope of this publication.

Warning

The illustration shows the DC power supply terminal block. Wire the DC power supply using the

appropriate lugs at the wiring end, as illustrated. The proper wiring sequence is ground to ground,

positive to positive (line to L), and negative to negative (neutral to N). Note that the ground wire should

always be connected first and disconnected last.
