Cisco VCO/4K Mechanical Assemblies
3.0 DESCRIPTION
The Storage I/O Module is two card slots wide and slides into the back of the VCO system where
it plugs into the control midplane. All outside connections are mounted on the faceplate of the
module. All internal connectors are mounted on the board itself for easy access to system
internals (for example, SCSI and Ethernet).
The VCO/4K system hard drive is mounted on the upper portion of the I/O Module. The board
is built to accommodate a 3.5 inch hard drive. Physical mounting points are provided for the
hard drive as well as a 50-pin SCSI interface to the system controller. There is also a provision
for an external SCSI connection on the front panel. The SCSI connection is reserved for future
use.
