Attaching network and power cables
Network and power cables must be attached to make sure that there are redundant
power and network connections, and dressed to allow for easy maintenance in the
future.
The following image shows you how to attach your internal network and power cables
for a node pair. Both node pairs in a chassis must be cabled in the same way.

Work with the site manager to determine external network connections, and bundle
the additional network cables together with the internal network cables from the same
node pair.
It is important to keep future maintenance in mind as you dress the network and
power cables. Cables must be dressed loosely enough to allow you to:
l
remove any of the four compute nodes from the back of the Generation 6 chassis.
l
remove power supplies from the back of compute nodes.
In order to avoid dense bundles of cables, you can dress the cables from the node
pairs to either side of the rack. For example, dress the cables from nodes 1 and 2
toward the lower right corner of the chassis, and dress the cables from nodes 3 and 4
toward the lower left corner of the chassis.
Wrap network cables and power cables into two separate bundles to avoid EMI
(electromagnetic interference) issues, but make sure that both bundles easily shift
