IIMLM01 Multibus Loop Module and IIMCP01 (Plant Loop sys-
tem) or IIMCP02 (INFI-NET system) Multibus Communication
Processor Module.
The MCL module of the multibus card cage connects to the
loop. Front edge connectors on the MCL module terminate a
redundant coaxial or twinaxial cable of the loop. A ribbon cable
connects the MCL module to the MLM module in slot two. The
MLM module converts analog loop signals to digital format for
the MCP module. A ribbon cable connects the MLM module to
the MCP module. The MCP module is located in slot three. It is
the network interface unit (NNIU01) processor card. A cable
connects the MCP module to the SCSI bus.
The IIMKM02A keyboard interface provides a connection for
the keyboard, all user interfaces, and the system reset signal.
A cable connects the MKM module to the keyboard connector
on the CPU. The IIMRM02 reset module (for driver cabinets,
used in place of IMKM02A) provides module bus reset and is
located in slot four.
The CPU in the OIS console may control up to two monitors on
the OIS console. Monitor cable(s) plug into the connectors on
the back of the monitor. The CPU also allows communications
with the printers on the ethernet network cable.
The OIS has a 3.5-inch, 2.88-megabyte floppy disk drive with
controller. The CPU has two 1.08 gigabyte hard disk drives;
one for the VMS operating system, the other for OIS applica-
tions. A SCSI connection is provided for data storage and
retrieval on DAT tape or optical disk. Commands between the
OIS and the auxiliary OIC consoles pass through an ethernet
network cable using either DECnet or TCP/IP protocol. Refer
to
for more information on OIS43 modules and
units. An internal CD-ROM drive located in the front of the
CPU provides for software installation and start-up. It provides
the means to load both disk drives using current software
release CDs.
