Note The DC site power source must be disconnected to ensure proper safety is maintained.

Step 5 Loosen the three locking screws for the negative, positive, and ground screw connectors on the DC power supply terminal block as follows:

a.Remove the –48 VDC lead (black) from the terminal block negative connector (–). (See 1 in Figure 3-3.)

b.Remove the +48 VDC lead (white wire) from the terminal block positive connector (+). (See 2 in Figure 3-3.)

c.Remove the safety ground lead (green wire) from the terminal block ground connector. (See 3 in Figure 3-3.)

Verifying That the Router Is Powered Down

Check the following to ensure that your router is properly powered down:

LED lights are off.

Fans are not running.

Power switch indicates the power supply is turned to the off position (O).

Power is disconnected at the source.

Removing the Cable-Management System

The cable-management system, located on the front of the Cisco 10720 Internet Router, organizes the interface cables that lead into and away from the router. To keep the cables free of sharp bends, extend the cables from the center out both sides of the cable-management tray. Excessive bending of an interface cable can degrade performance and possibly harm the cable. The cable-management system consists of the cable-management tray and the cable-management cover.
