The 48-U rack offers several features that simplify cable routing
(see Figure 1-16).
The power distribution unit (PDU) channels in each rack flange allow you
to route power cables to the systems mounted in the rack.
Cable clips can be mounted in the PDU channels to keep cables out of the
way and help prevent cords from becoming tangled.
You can route cables out of the rack in two ways on a standard configuration:
Through the cable exit at the bottom of the back doors (see Figure 1-16).
Through the adjustable cable slot at the top of the rack and into a cable
raceway (see Figure 1-16).
