Chapter 3 Installing the Cisco 7204 Providing a Chassis Ground Connection for the Router Chassis To secure port adapter interface cables to the cable-management brackets, complete the following steps: Note The eight removable tie wraps installed on the cable-management brackets secure port adapter interface cables to the brackets. We recommend that you use the tie wraps that shipped with the cable-management brackets. You can use standard tie wraps; however, you will have to cut and replace them with new tie wraps when you want to release or secure an interface cable to a bracket. Step 1 Step 2 Select a tie wrap and release its locking mechanism. Carefully lace the interface cables from a port adapter installed in the chassis between the two ends of the unlocked tie wrap. Note Be sure to leave a small service loop in the interface cable before securing it to the cable-management bracket. Step 3 With the interface cables between the ends of the tie wrap and the interface cables' service loop in place, tighten the cable tie down around the interface cables until they are secured against the cable-management bracket.

Installing the Cisco 7204
Providing a Chassis Ground Connection for the Router Chassis
To secure port adapter interface cables to the cable-management brackets, complete the following steps:
Note
The eight removable tie wraps installed on the cable-management brackets secure port adapter interface
cables to the brackets. We recommend that you use the tie wraps that shipped with the cable-management
brackets. You can use standard tie wraps; however, you will have to cut and replace them with new tie
wraps when you want to release or secure an interface cable to a bracket.
Step 1
Select a tie wrap and release its locking mechanism.
Step 2
Carefully lace the interface cables from a port adapter installed in the chassis between the two ends of
the unlocked tie wrap.
Note
Be sure to leave a small service loop in the interface cable before securing it to the
cable-management bracket.
Step 3
With the interface cables between the ends of the tie wrap and the interface cables’ service loop in place,
tighten the cable tie down around the interface cables until they are secured against the
cable-management bracket. (Refer to
Figure 3-10
