IBM 42U SlimRack 7965-94Y
The 2.0-meter (79-inch) Model 7965-94Y is compatible with past and present 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 placed on
standard 24-inch floor tiles.
The IBM 42U Slim Rack has a lockable perforated front steel door that provides 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 placed horizontally, but they each use 1U of space in this position.
The AC power distribution unit and rack content
For rack models T00 and T42, 12-outlet PDUs are available. These PDUs include the AC
power distribution unit #7188 and the AC Intelligent PDU+ #7109. The Intelligent PDU+ is
identical to #7188 PDUs, but it is equipped with one Ethernet port, one console serial port,
and one RS232 serial port for power monitoring.
The PDUs have 12 client-usable IEC 320-C13 outlets. Six groups of two outlets are fed by six
circuit breakers. Each outlet is rated up to 10 amps, but each group of two outlets is fed from
one 15 amp circuit breaker.
