The VS-11 family of SUN-compatible chassis offers the choice of stnadard rack mounting, tower mounting or table top mounting. The family has two basic configurations to meet your needs: The VSS-11/Model 30 is a fully-integrated chassis providing both card cage and mass storage. The VCS-11/Model 20 is a smaller, card cage only chassis. (Mass storage only chassis with the same styling as the VS-11 chassis are available in the Zoltech VV-11 series, the Model 16's.)

In the rack mounted configuration these chassis require only 5¼" of vertical rack space to hold all of the basic components of a SUN-compatible system. The VSS-11/Model 30 houses up to 5 9U x 400mm card slots, one or two 5¼" full height drives, up to 700W of system power plus cooling, control panel and internal power distribution in only 31" of rack depth. The VCS-11/Model 20 provides the same capability, except for the drive bays, in only 25½" of rack depth.

Flexible Cable Management    The VSS-11/Model 30 makes the assembly of integrated systems easy by providing cable slots between the card cage and the outer chassis. Mass storage device cables that originate on the faceplates of the circuit modules can be routed to the drives inside of the chassis through these slots. When the disk or tape interface is present on the J2 or J3 connector, the cabling to internal devices can be made with a short length of ribbon cable from the backplane across the power supply to the drives. The cable access slot also allows cables for external devices that originate on the backplane to be routed to the outside of the chassis.
