32 IBM Power 750 and 760 Technical Overview and Introduction
Rear Door Heat Exchanger
To lead away more heat a special door, called a Rear Door Heat Exchanger (FC 6858), is
available. This door replaces the standard rear door on the rack. Copper tubes are attached
to the rear door to circulate chilled water, which is provided by the customer. The chilled water
removes heat from the exhaust air being blown through the servers and attachments mounted
in the rack. The water lines in the door attach to the customer-supplied secondary water loop
using industry standard quick couplings.
For details about planning for the installation of the IBM Rear Door Heat Exchanger, see the

1.13.3 Feature code 0551 rack
The 1.8-meter rack (FC 0551) is a 36U (EIA units) rack. The rack that is delivered as FC 0551
is the same rack delivered when you order the 7014-T00 rack. The included features might
differ. Several features that are delivered as part of the 7014-T00 must be ordered separately
with the FC 0551.
1.13.4 Feature code 0553 rack
The 2.0-meter rack (FC 0553) is a 42U (EIA units) rack. The rack that is delivered as FC 0553
is the same rack delivered when you order the 7014-T42 or B42 rack. The included features
might differ. Several features that are delivered as part of the 7014-T42 or B42 must be
ordered separately with the FC 0553.
1.13.5 The AC power distribution unit and rack content
For rack models T00 and T42, 12-outlet PDUs are available. These include the AC power
distribution units FC 9188 and FC 7188 and the AC Intelligent PDU+ FC 5889 and FC 7109.
The Intelligent PDU+ (FC 5889 and FC 7109) is identical to FC 9188 and FC 7188 PDUs but
are equipped with one Ethernet port, one console serial port, and one RS232 serial port for
power monitoring.
The PDUs have 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.
