This chapter describes the physical characteristics of the tall (42U) ICE 8400 racks in the following sections:
At the time this document was published only the tall (42U) Altix ICE rack (shown in Figure 4-2) was approved for ICE system racks shipped from the SGI factory.
The tall rack (shown in Figure 4-1) has the following features and components:
Front and rear door. The front door is opened by grasping the outer end of the rectangular-shaped door piece and pulling outward. It uses a key lock for security purposes that should open all the front doors in a multi-rack system (see Figure 4-2).
Note: The front door and rear door locks are keyed differently. The optional water-chilled rear door (see Figure 4-3) does not use a lock. The standard rear door has a push-button key lock to prevent unauthorized access to the system. The rear doors have a master key that locks and unlocks all rear doors in a system made up of multiple racks. You cannot use the rear door key to secure the front door lock.
Cable entry/exit area. Cable access openings are located in the front floor and top of the rack. Cables are only attached to the front of the IRUs; therefore, most cable management occurs in the front and top of the rack. Stand-alone administrative, leader and login server modules are the exception to this rule and have cables that attach at the rear of the rack. Rear cable connections will also be required for optional storage modules installed in the same rack with the IRU(s). Optional inter-rack communication cables pass through the top of the rack. I/O and power cables normally pass through the bottom of the rack.
Rack structural features. The rack is mounted on four casters; the two rear casters swivel. There are four leveling pads available at the base of the rack. The base of the rack also has attachment points to support an optional ground strap, and/or seismic tie-downs.
Power distribution units in the rack. Up to thirteen outlets are required for a single IRU system as follows:
up to 7 outlets for an IRU (depending on confguration)
4 outlets for administration and RLC servers (in primary rack)
2 outlets for a service node (server)
Allow six or seven more outlets for each additional IRU in the system
Two single-phase power distribution units (PDUs) are needed for a base rack system,
(8 outlets per PDU). A three-phase power distribution unit has 18 outlet connections, up to 14 of them may be needed to power two IRUs.Note: System IRUs that use high-wattage processors require seven power supplies and take up all but one of the available plugs in a single-phase PDU.
