2-2 Stratus ftServer V 100, V 200, and V 400 Systems: Site Planning Guide (R543)
Each PDU receives power from its power source (through a permanently attached
power input cord) and distributes power to the components inside the cabinet (through
six power outlets and a permanently attached power output cord).
The top PDU in the cabinet receives power from the A-side power source (typically a
UPS unit) and distributes power to:
 The A-side of the system backplane
 The A-side of the optional network I/O enclosure
 One side of each FC disk enclosure
 The AA-T53300 SDLT Single Tape-Drive Enclosure or AA-T53400 SDLT Dual
Tape-Drive Enclosure
The bottom PDU in the cabinet receives power from the B-side power source (typically
a UPS unit) and distributes power to:
 The B-side of the system backplane, in stand-by mode (the B-side power source is
used if power to the A-side source is interrupted)
 The B-side of the optional network I/O enclosure, in stand-by mode (the B-side
power source is used if power to the A-side source is interrupted)
 One side of each FC disk enclosure
AC Power and HVAC Worksheets
When planning for the system’s electrical needs, consider the following:
 The AC power service required at the site
 The number and types of the power outlets
 Power cord lengths, plug types, and current rating
This section contains the following worksheets:
 Table 2-1, a site planning worksheet for determining the number and types of AC
outlets required at the site and the lengths of the power cords. See ‘‘Power Cord
Summary’’ on page 2-10 for more information about power cords.
 Table 2-2, a site planning worksheet for AC power and HVAC requirements.
Place check marks in the boxes for those products that you have purchased. For each
row that you check marked in Table 2-1:
 Fill in the Quantity of Product Purchased column.
 Multiply it by the supplied value in the No. of AC Outlets Required column.
 Write the result in the Subtotal of AC Outlets column.
