Installing the Rackmount Command
Module
This procedure explains how to install a rackmount command
module in a Data Center cabinet and how to connect the cables.
Power Cord Routing Notes
The command module uses two power cords, one for each power
supply. The Data Center has two AC distribution boxes. Each AC
distribution box has its own power cord. There are three options for
connecting power to a rackmount command module in a Data
Center cabinet (
Figure 6 ):
●
Option 1 (Preferred): Redundant power to cabinet and
command module.
Connect the AC distribution boxes to
independent, external power receptacles. Connect one power
cord from the command module to each AC box in the Data
Center cabinet or to independent, external power receptacles.
●
Option 2: Redundant power to cabinet, non-redundant to
command module.
Connect the AC distribution boxes to
independent power sources. Connect both power cords from the
command module to one AC box in the Data Center cabinet.
●
Option 3: Non-redundant power to cabinet and command
module.
Connect both AC distribution boxes to a single power
source. Connect both power cords from the command module to
one or both AC boxes in the Data Center cabinet.
Because of the limited space inside the Data Center cabinet, it may be
easier to connect and route power cords before you begin installing
support rails and the command module. If you intend to connect the
command module to the cabinet’s internal power unit, consider
connecting and routing the power cords in the cabinet before you
install the command module.
