Cable Management Options

8.0CABLE MANAGEMENT OPTIONS

The XDF is able to host many of the components of the Foundation cable management products. These optional items deliver a flexible solution to rack-enclosure cable problems by utilizing a patent pending platform to provide adaptive equipment and cabling support. Cable and equipment mounting options are available to meet changing requirements.

8.1Cable Management Considerations

When designing the equipment layout in the XDF, consider how cables must be run for each configu- ration and how cable runs affect cooling, access and operational factors. Separate power and commu- nication cables to reduce electromagnetic interference.

Good cable management contributes to:

Effective airflow for cooling

Easier cable identification

Improved access

Reduced electromagnetic interference

Proper bend radii, particularly for fiber optic cables

Adequate support for large cables and heavy cable bundles

Several Foundation options are designed to facilitate structured cable management. These are described in 8.4 - Optional Cable Management Channel.

NOTE

When installing cables, leave enough slack for the unit to be rolled forward or sideways. Do not block or restrict cooling system discharge or return airflow.

Do not defeat the ground/earth connections between the utility/mains outlet and the XDF.

8.2Cable Management

Once your equipment has been installed, you are ready to connect cables for power and communica- tion. Before making any connections, check the equipment to ensure that all power switches are in the OFF position.

Numerous cable entrances and management provisions are built into the XDF to ease cable installa- tion.

Optional cable rings and Velcro straps, along with some components for routing cables, can be used with the XDF. These help not only to keep your cables organized but also separate power and commu- nications cables, reducing electromagnetic interference. A wide area is provided on the left rear side of the frame to mount cable rings, Velcro straps and cable trays. This location contributes to cooling effi- ciency by keeping equipment cables out of the cooling air pattern (see Figure 26).
