Preparing the Rack
This section contains information about power cord routing and
support rail installation.
Power Cord Routing Information
The expansion unit uses two power cords. You can connect these
power cords to the primary power units inside the rack, such as an
ac distribution unit or uninterruptible power supply (UPS), or to an
external source, such as remote power units, a UPS, or wall outlet.
Both power cords can use the same power source or a separate
power source, as long as they meet the power requirements defined
in Table 1 on page 24.
Because of the limited space in some racks, it might be easier to
connect and route cables before you install the mounting brackets
and hardware devices. If you intend to connect the expansion unit
to the cabinet's internal power unit, consider connecting and routing
the expansion unit power cords in the cabinet before you install the
expansion unit.
Support Rail Installation Information
To install the expansion unit in a rack, use the mounting hardware
(provided with your hardware kit) to:
Provide a level, stable support for the expansion unit chassis
Support the expansion unit weight
Properly position the expansion unit in the rack to allow proper
air circulation around and through the expansion unit
The exact placement of the mounting hardware in the rack will
depend on how your rack is constructed and where (vertically) you
intend to install the expansion unit.
Use this procedure to set up the rack and prepare to install the
expansion unit.
Note: During this installation, you might need to access the interior
of the rack to attach mounting hardware or to route power
and SCSI cables. Also, you must have enough room around
