Chapter 1. General description 111.5 System racksThe Enterprise Rack Models T00 and T42 are 19-inch wide racks for general use withIBM Sserver p5, pSeries, and RS/6000 rack-based or rack drawer-based systems. Theracks provide increased capacity, greater flexibility, and improved floor space utilization.The p5-550 uses a 4U rack-mounted server drawer.If a p5-550 system is to be installed in a non-IBM rack or cabinet, you should ensure that therack conforms to the EIA 1 standard EIA-310-D (see 1.5.6, “OEM rack” on page 14).1.5.1 IBM RS/6000 7014 Model T00 Enterprise RackThe 1.8-meter (71 inch) Model T00 is compatible with past and present p5, pSeries, andRS/6000 racks and is designed for use in all situations that have previously used the olderrack models R00 and S00. The T00 rack has the following features: 36 EIA units (36U) of usable space. Optional removable side panels. Optional highly perforated front door. Optional side-to-side mounting hardware for joining multiple racks. Standard black or optional white color in OEM format. Increased power distribution and weight capacity. An optional reinforced (ruggedized) rack feature (FC 6080) provides added earthquakeprotection with modular rear brace, concrete floor bolt-down hardware, and bolt-in steelfront filler panels. Support for both AC and DC configurations. DC rack height is increased to 1926 mm (75.8 inches) if a power distribution panel is fixedto the top of the rack. Up to four Power Distribution Units (PDUs) can be mounted in the proper bays, but otherscan fit inside the rack. See 1.5.3, “AC Power Distribution Unit and rack content” onpage 12. Optional rack status beacon (FC 4690). This beacon is designed to be placed on top of arack and cabled to servers, such as a p5-550, and other components, such as a 7311 I/Odrawer, inside the rack. Servers can be programmed to illuminate the beacon in responseto a detected problem or changes in system status. A rack status beacon junction box (FC 4693) should be used to connect multiple serversand I/O drawers to the beacon. This feature provides six input connectors and one outputconnector for the rack. To connect the servers or other components to the junction box orthe junction box to the rack, status beacon cables (FC 4691) are necessary. Multiplejunction boxes can be linked together in a series using daisy chain cables (FC 4692). Weight:1 Electronic Industries Alliance (EIA). Accredited by American National Standards Institute (ANSI), EIA provides aforum for industry to develop standards and publications throughout the electronics and high-tech industries.Note: It is the customer’s responsibility to ensure that the installation of the drawer in thepreferred rack or cabinet results in a configuration that is stable, serviceable, safe, andcompatible with the drawer requirements for power, cooling, cable management, weight,and rail security.
