NEC 5800/180Ra-7 User Manual

The dual-hinged cable retention arm attaches to the rear of the BSU and allows
cables to swing in and out of the way as the BSU slides back and forth within
the rack cabinet. All the BSU cables can be tie-wrapped to the cable retention
arm.

For easy installation of the cable retention arm,

first slide the BSU into the rack cabinet and then install the
cable retention arm.

BSU (see Figure 2-9).

2.  Using two screws attach the other end of the cable retention arm to the cage

nuts installed in the left rear vertical mounting rail (see Figure 2-9).

3.  Bundle all the BSU cables together and tie-wrap them to the cable retention

arm.
