Installation Guide
6 Reinstall the air channel by reversing the process used to remove the air
channel.
NOTE:
The air channel must always remain at the bottom of the rack (in 1U
and 2U) and must not be moved to a different location in the rack.
NOTE:
Unless you need to couple two or more racks, you may now install
systems into the rack. For information on installing components in the rack, see
the white numbered labels on the front and back of the rack mounting rails.
Routing Cables
The rack offers several features that simplify cable routing. See Figure 21.
• 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 prevent cables 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 21.
• Through the adjustable cable slot at the top of the rack and into a cable
raceway. See Figure 21.
