14 IBM Power System S822 Technical Overview and Introduction
򐂰 The Front Door for a 2.0 m Rack (#6069) is made of steel, with a perforated flat front
surface. The perforation pattern extends from the bottom to the top of the door to enhance
ventilation and provide some visibility into the rack. This door is non acoustic and has a
depth of about 25 mm (1 in).
򐂰 The 2.0 m Rack Acoustic Door (#6249) consists of a front and rear door to reduce noise
by approximately 6 dB(A). It has a depth of approximately 191 mm (7.5 in).
򐂰 The High-End Appearance Front Door (#6250) provides a front rack door with a
field-installed Power 780 logo indicating that the rack contains a Power 780 system. The
door is not acoustic and has a depth of about 90 mm (3.5 in).
򐂰 The #ERG7 provides an attractive black full height rack door. The door is steel, with a
perforated flat front surface. The perforation pattern extends from the bottom to the top of
the door to enhance ventilation and provide some visibility into the rack. The non-acoustic
door has a depth of about 134 mm (5.3 in).
Rear Door Heat Exchanger
To lead away more heat, a special door named the Rear Door Heat Exchanger (#6858) is
available. This door replaces the standard rear door on the rack. Copper tubes that are
attached to the rear door circulate chilled water, provided by the customer. The chilled water
removes heat from the exhaust air being blown through the servers and attachments mounted
in the rack. With industry standard quick couplings, the water lines in the door attach to the
customer-supplied secondary water loop.
For details about planning for the installation of the IBM Rear Door Heat Exchanger, see the

1.8.3 IBM 42U Slim Rack 7965-94Y
The 2.0-meter (79-inch) model 7965-94Y is compatible with past and present IBM Power
Systems servers and provides an excellent 19-inch rack enclosure for your data center. Its
600 mm (23.6 in.) width combined with its 1100 mm (43.3 in.) depth plus its 42 EIA enclosure
capacity provides great footprint efficiency for your systems and allows it to be easily located
on standard 24-inch floor tiles.
The IBM 42U Slim Rack has a lockable perforated front steel door, providing ventilation,
physical security, and visibility of indicator lights in the installed equipment within. In the rear,
either a lockable perforated rear steel door (#EC02) or a lockable Rear Door Heat Exchanger
(RDHX)(1164-95X) is used. Lockable optional side panels (#EC03) increase the rack's
aesthetics, help control airflow through the rack, and provide physical security. Multiple 42U
Slim Racks can be bolted together to create a rack suite (indicate #EC04).
Up to six optional 1U PDUs can be placed vertically in the sides of the rack. Additional PDUs
can be located horizontally, but they each will use 1U of space in this position.
High end: For the High-End Appearance Front Door (#6250), use the High-End
Appearance Side Covers (#6238) to make the rack appear as though it is a high-end
server (but in a 19-inch rack format instead of a 24-inch rack).
