System Specifications
The basic unit of the GS80 system consists of a single cabinet that contains one
or two drawers (QBBs), power supplies, a PCI box, and a storage shelf.
Additional I/O and storage facilities are accommodated in an expander cabinet
attached to the system unit.
In the GS160/320 line, the basic system is the GS160. It consists of a power
cabinet and system cabinet 1. The power cabinet contains the power supplies,
the I/O components—the PCI boxes and storage shelves—and the OCP
(operator control panel). System cabinets house one or two system boxes. Each
system box has two QBBs that are paired back-to-back and rotated 180
0 with
reference to each other.
The basic system can be upgraded to contain two system boxes. An upgrade to
three or four system boxes requires the addition of system cabinet 2 (GS320).
