Storage/Control I/O Module
The Storage/Control I/O Module performs two functions: to connect outside interfaces to the system
controller and to house the hard disk drive. It plugs into the back of the VCO/4K system and provides
the I/O interfaces for system peripheral devices and host communication links using four serial ports,
one Ethernet port, one printer port and one SCSI connector. Figure 4-1 shows the front panel of the
Storage/Control I/O Module.
Physical interfaces to host computers and peripheral devices are provided on the front panel of the
Storage/Control I/O Module. Two serial ports are available for SIO host links, and another two are
dedicated to supporting the local system administration console and a remote maintenance modem. An
Ethernet Transceiver interface and parallel printer connector are also located on the Storage/Control I/O
Module.
