32 IBM Power 770 and 780 Technical Overview and Introduction
The Base/Side Mount Universal PDU (#9188) and the optional, additional, Universal PDU
(#7188) and the Intelligent PDU+ options (#7109) support a wide range of country
requirements and electrical power specifications. The PDU receives power through a
UTG0247 power line connector. Each PDU requires one PDU-to-wall power cord. Various
power cord features are available for different countries and applications by varying the
PDU-to-wall power cord, which must be ordered separately. Each power cord provides the
unique design characteristics for the specific power requirements. To match new power
requirements and save previous investments, these power cords can be requested with an
initial order of the rack or with a later upgrade of the rack features.
The PDU has 12 client-usable IEC 320-C13 outlets. There are six groups of two outlets fed by
six circuit breakers. Each outlet is rated up to 10 amps, but each group of two outlets is fed
from one 15 amp circuit breaker.
The Universal PDUs are compatible with previous models.
1.12.8 Rack-mounting rules
The system consists of one to four CEC enclosures. Each enclosure occupies 4U of
vertical rack space. The primary considerations to account for when mounting the system into
a rack are:
򐂰 For configurations with two, three, or four drawers, all drawers must be installed together in
the same rack, in a contiguous space of 8 U, 12 U, or 16 U within the rack. The uppermost
enclosure in the system is the base enclosure. This enclosure will contain the active
service processor and the operator panel. If a second CEC enclosure is part of the
system, the backup service processor is contained in the second CEC enclosure.
򐂰 The 7014-T42, -B42, or #0553 rack is constructed with a small flange at the bottom of EIA
location 37. When a system is installed near the top of a 7014-T42, -B42, or #0553 rack,
no system drawer can be installed in EIA positions 34, 35, or 36. This approach is to avoid
interference with the front bezel or with the front flex cable, depending on the system
configuration. A two-drawer system cannot be installed above position 29. A three-drawer
system cannot be installed above position 25. A four-drawer system cannot be installed
above position 21. (The position number refers to the bottom of the lowest drawer.)
򐂰 When a system is installed in an 7014-T00, -T42, -B42, #0551, or #0553 rack that has no
front door, a Thin Profile Front Trim Kit must be ordered for the rack. The required trim kit
for the 7014-T00 or #0551 rack is #6263. The required trim kit for the 7014-T42, -B42, or
#0553 rack is #6272. When upgrading from a 9117-MMA, trim kits #6263 or #6272 can be
used for one drawer enclosures only.
Note: Ensure that the appropriate power cord feature is configured to support the power
being supplied.
Notes: Based on the power cord that is used, the PDU can supply from 4.8 - 19.2 kVA.
The total kilovolt ampere (kVA) of all the drawers that are plugged into the PDU must not
exceed the power cord limitation.
Each system drawer to be mounted in the rack requires two power cords, which are not
included in the base order. For maximum availability, be sure to connect power cords from
the same system to two separate PDUs in the rack, and to connect each PDU to
independent power sources.
