Each system bay is powered by two redundant power distribution units (PDUs), one PDU for each

Option 1: Replace the rear top cover of the bay with the ceiling routing top cover, described in
Overhead routing kit
on page 84, which allows the power cables inside the machine to be
routed out through the top.
Option 2: "Drop" the power cables down the hinge side, to the bottom, and route them inside
the machine.
