This chapter describes the physical characteristics of the tall (42U) UV 1000 racks in the following sections:
At the time this document was published only the tall (42U) Altix rack (shown in Figure 4-2) was available from the SGI factory for use with the Altix UV 1000 systems. Other racks may be available to house the system IRUs, check with your SGI sales or service representative for information.
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. Multiple cables are attached to the front of the IRUs; therefore, a significant part of the cable management occurs in the front part of the rack. The stand-alone system management nodes 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 can pass through the top of the rack. These are necessary whenever the system consists of multiple racks. 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. Ten outlets are required for a single IRU system as follows:
Allow eight outlets for the first IRU
Two outlets for a maintenance node (server)
Allow eight more outlets for each additional IRU in the system
Eight two-outlet single-phase power distribution units (PDUs) are needed for a base rack system with two IRUs.
In addition an 8 outlet single-phase PDU is required for the system management node and other optional equipment. Each three-phase power distribution unit has 9 outlet connections; 18 outlets are required to power two IRUs.
