Cable Management Device Preinstallation Guidelines

Before you install any cable management device in a rack, determine 
which cable management device rack-mount position is best by 
examining the:

Location in the rack where you plan to install the chassis 

Depth of the rack in which you plan to install the chassis

Space required for proper ventilation of the chassis

Space required for module cables to bend 

Proximity of other devices in the rack and their installation or 
environmental requirements

Install the 7-slot chassis in your rack before you install the cable 
management device.

You can install the cable management device only on the preinstalled 
chassis rack-mount flanges. Do not install the optional cable 
management device on the alternate position chassis rack-mount 
flanges. If your rack has a door, you must leave the door open to 
provide space for the cable management device.

Installing the Cable Management Device

To install the cable management device for a 7-slot chassis, follow 
these steps:

1

Remove the screws from the top open slot position on the right chassis 
rack-mount flange and the bottom open slot position (Figure 11).

2

Place the cable management device flush up against the right 
rack-mount flange, with the top of the cable management device at 
the top open slot position on the chassis rack-mount flange (Figure 11).

The bottom slot of the cable management device aligns with the 
bottom open slot of the chassis rack-mount flange.
