Chapter 1. General description

1.10.3 IBM 7965 model 94Y rack

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 fit easily 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 feature code
#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 use 1U of space in this position.

A minimum of one of the following features is required:

򐂰

Feature #ER2B allows you to reserve 2U of space at the bottom of the rack.

򐂰

Feature #ER2T allows you to reserve 2U of space at the top of the rack.

1.10.4 Feature code #0551 rack

The 1.8-meter rack (#0551) is a 36U (EIA units) rack. The rack that is delivered as #0551 is
the same rack that is 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 feature code #0551. The #0551 is available with an initial order of a
Power E850C server.

1.10.5 Feature code #0553 rack

The 2.0-meter rack (#0553) is a 42U (EIA units) rack. The rack that is delivered as #0553 is
the same rack that is delivered when you order the 7014-T42. The included features might
differ. Several features that are delivered as part of the 7014-T42 or must be ordered
separately with the #0553. The #0553 is available with an initial order of a Power E850C
server.

1.10.6 The ac power distribution unit and rack content

For rack models T00, T42, and the slim 94Y, 12-outlet PDUs are available. The following
PDUs are available:

򐂰

PDUs Universal UTG0247 Connector (#7188)

򐂰

Intelligent PDU+ Universal UTG0247 Connector (#7109)

򐂰

High Function 9xC19 PDU: Switched, Monitoring (#EPTJ)

򐂰

High Function 9xC19 PDU 3-Phase: Switched, Monitoring (#EPTL)

򐂰

High Function 12xC13 PDU: Switched, Monitoring (#EPTN)

򐂰

High Function 12xC13 PDU 3-Phase: Switched, Monitoring (#EPTQ)

When mounting the horizontal PDUs, it is a good practice to place them almost at the top or
almost at the bottom of the rack, leaving 2U or more of space at the top or bottom of the rack
for cable management. Mounting a horizontal PDU in the middle of the rack is not optimal for
cable management.
