Installing the System in a Distribution Rack
You can mount the system into a 19-inch distribution
rack. This section describes how to prepare the
system and distribution rack for installation and how
to mount the system in the rack.
Install your distribution rack near an easily accessible
power outlet. You can power down the system only
by removing the power cord from the power source.
