Cable Management
Cable Management
A fully loaded multi-MGX 8220 rack can have between 150 and 200 cables attached to the racks
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 are required.
The cable management kits are installed to the rear of the cooling module, the booster cooling module,
and the plenum as required.
Note A 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, necessary brackets, screws, and washers
for rear mounting on the plenum as shown in Table 7-1.
A cable management kit for the plenum is shown in Figure 7-16. Install the kit as follows:
Step 1 Install the two inner brackets onto the sides of the plenum chamber, one on 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, page 7-10.
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.
