1.12.2 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 differ in the model T42 rack 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 FC ERG7 feature 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.
1.12.3 IBM 7014 model S25 rack
The 1.3-meter (49-inch) model S25 rack has the following features:
򐂰 25U (EIA units)
򐂰
Weights:
– Base empty rack: 100.2 kg (221 lb)
– Maximum load limit: 567.5 kg (1250 lb)
The S25 racks do not have vertical mounting space that accommodate FC 7188 PDUs. All
PDUs required for application in these racks must be installed horizontally in the rear of the
rack. Each horizontally mounted PDU occupies 1U of space in the rack, and therefore
reduces the space available for mounting servers and other components.
1.12.4 IBM 7953 model 94Y rack
The 2.0-meter (79.3 inch) model 94Y rack has the following features:
򐂰 42U (EIA units)
򐂰
Weights:
– Base empty rack: 187 kg (221 lb)
– Maximum load limit: 664 kg (1460 lb)
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 the rack can support in a zone 4 earthquake environment is 445 kg (980
lb). In the zone 4 earthquake environment the rack should be configured starting with the
heavier drawers at the bottom of the rack.
High end: A special door (FC 6250) and side panels (FC 6238) are available to make the
rack appear as a high-end server (but in a 19-inch rack format instead of a 24-inch rack).
S25 or B25 rack: The Power 780 cannot be ordered with a S25 or B25 rack.
