SGI UV 3000 Series Rack (42U)

54
The tall rack (shown in Figure 4-1 on page 55) 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 on page 56).
Note: The front door and rear door locks are keyed differently. The rear lock on an air-cooled
rack is shown in Figure 4-1 on page 55. The optional water-chilled rear door (see Figure 4-3
on page 57) 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 optional system
administration node, system console and any optional storage modules installed in the same
rack with the IRU(s) use rear cable management. 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. Up to 15 outlets may be required for a single-rack
IRU system as follows:
– Allow three outlets for the first IRU
– Two outlets for an optional administration node (server)
– One outlet for an optional administration console
– Two outlets for each storage or PCIe expansion chassis
– Allow three more outlets for each additional IRU in the system
Note than an eight outlet single-phase PDU may be used for the administration node and
other optional equipment.
