7-22 Cisco MGX 8220 Reference, Release 4.1

Cable Management

A fully loaded multi-MGX 8220 rack may have between 150 and 200 cables attached to the rack’s

modules. Cable management kits are available for installation on the rear of rack modules. These

kits provide the means to route the power and data cables in a neat and orderly fashion to and from

the modules in the rack. Depending upon the number of racks in the shelf and the number of cables

connected to the shelves, one or more cable management kits may be required.

The cable management kits are installed to the rear of the cooling module, the booster cooling

module, and the plenum as required.

NoteA cable management kit cannot be installed on the spacer unit.

There are two basic cable management kits:

1 Plenum chamber kit

2 Cooling and booster cooling kit

Plenum Chamber Kit

The plenum chamber kit consists of a cable management panel and the necessary brackets, screws

and washers for rear mounting on the plenum as shown in Table7-1.

Table7-1 Plenum Chamber Kit Bill of Material

A cable management kit for the plenum is shown in Figure7-16. Install the kit as follows:

Step 1 Install the two inner brackets onto the sides of the plenum chamber, one each side using two

thread forming screws for each bracket. If a rear rail is being used to mount the plenum, use

the protruding flange to attach to the rail using two thread forming screws and washers

(supplied with the plenum install kit). If there is limited access, use the procedures

described in the section, “Rack Mounting the Modules”, under Limited Access in this

chapter.

Step 2 Install the two outer brackets onto the two inner brackets using two screws with locking

nuts for each bracket.

Step 3 Install the cable management panel onto the outer brackets using two screws, locking nuts,

and washers for each bracket.
