IBM Power 720 and 740 Technical Overview and Introduction
1.14.3 IBM 7014 Model T42 rack
The 2.0-meter (79.3-inch) Model T42 addresses the client requirement for a tall enclosure to
house the maximum amount of equipment in the smallest possible floor space. The following
features are for the model T42 rack (which differ from the model T00):
򐂰 The T42 rack has 42U (EIA units) of usable space (6U of additional space).
򐂰
The model T42 supports AC power only.
򐂰 Weights are as follows:
– T42 base empty rack: 261 kg (575 lb)
– T42 full rack: 930 kg (2045 lb)
The T42 rack has various door options that are available, as shown in Figure 1-9.
Figure 1-9 Door options for the T42 rack
These door options are described in the following list:
򐂰 The 2.0 m Rack Trim Kit (FC 6272) is used, if no front door is used in the rack.
򐂰 The Front Door for a 2.0 m Rack (FC 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 feature (FC 6249) consists of a front and rear door to
reduce noise by about 6 dB(A). It has a depth of about 191 mm (7.5 in).
Important: If additional weight is added to the top of the rack, for example add feature
code 6117, the 490 kg (1080 lb) must be reduced by the weight of the addition. As an
example, feature code 6117 weighs approximately 45 kg (100 lb) so the new maximum
weight of drawers that the rack can support in a zone 4 earthquake environment is 445 kg
(980 lb). In the zone 4 earthquake environment, configure the rack by starting with the
heavier drawers at the bottom of the rack.
OEM front door: This door is also available as an OEM front door (FC 6084).
