򐂰 Up to four power distribution units (PDUs) can be mounted in the PDU bays (see
Figure A-2 on page 52), but others can fit inside the rack. For more information, see “The
AC power distribution unit and rack content” on page 51.
򐂰 For the T00 rack, three door options are available:
– Front Door for 1.8 m Rack (#6068)
This 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 visibility into the rack.
– A 1.8 m Rack Acoustic Door (#6248)
This feature provides a front and rear rack door that are designed to reduce acoustic
sound levels in a general business environment.
– A 1.8 m Rack Trim Kit (#6263)
If no front door is used in the rack, this feature provides a decorative trim kit for the
front.

Ruggedized Rack Feature
For enhanced rigidity and stability of the rack, the optional Ruggedized Rack Feature
(#6080) provides additional hardware that reinforces the rack and anchors it to the floor.
This hardware is for use in locations where earthquakes are a concern. The feature
includes a large steel brace or truss that bolts into the rear of the rack.
It is hinged on the left side so that it can swing out of the way for easy access to the rack
drawers when necessary. The Ruggedized Rack Feature also includes hardware for
bolting the rack to a concrete floor or a similar surface, and bolt-in steel filler panels for any
unoccupied spaces in the rack.
򐂰 The following weights apply to the T00 rack:
– T00 base empty rack: 244 kg (535 lb.).
– T00 full rack: 816 kg (1795 lb.).
– Maximum weight of drawers is 572 kg (1260 lb.).
– Maximum weight of drawers in a zone 4 earthquake environment is 490 kg (1080 lb.).
This number equates to 13.6 kg (30 lb.) per EIA.
IBM 7014 Model T42 rack
The 2.0-meter (79.3-in.) 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.
Important: If additional weight is added to the top of the rack, for example, by adding
#6117, the 490 kg (1080 lb.) weight must be reduced by the weight of the addition. As an
example, #6117 weighs approximately 45 kg (100 lb.), so the new maximum weight of the
drawers that the rack can support in a zone 4 earthquake environment is 445 kg (980 lb.).
In the zone 4 earthquake environment, the rack must be configured starting with the
heavier drawers at the bottom of the rack.
