SGI ICE XA Series D-Rack (42U)
The SGI tall D-Rack (shown in Figure 4-1 on page 47) 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 48). A
front door is required on every rack.
Note:
The front door and rear door locks are keyed differently. The optional water-chilled
rear doors (see Figure 4-2 on page 48) do not use a lock.
Up to four optional 10.5 U-high (18.25-inch) water-cooled panels can be installed on the rear
of the SGI ICE XA D-Rack.
Note that an air-cooled rack (that does not use water-cooling panels) has a rear key lock to
prevent unauthorized access to the system via the rear door. In a system made up of multiple
air-cooled racks, rear doors have a master key that locks and unlocks all rear doors in a
system. 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. Stand-alone administrative, leader and login server modules 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 service node enclosure(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 sixteen outlets may be required for a single
rack as follows:
–
4 outlets for administration and RLC servers
–
2 outlets for each service node (minimum of one server)
–
two outlets for each optional storage unit
Optional single-phase PDUs can be used in SGI ICE XA racks dedicated to service node or
I/O functionality.
