Hardware Preparation and Installation

The MVME2603/2604 front panel LEDs and switches are mounted on a 
removable mezzanine board. Removing the LED mezzanine makes the 
mezzanine connector (J1, a keyed double-row 14-pin connector) available 
for service as a remote status and control connector. In this application, J1 
can be connected to a user-supplied external cable to carry the Reset and 
Abort signals and the LED lines to a control panel located apart from the 
MVME2603/2604. Maximum cable length is 15 feet.

and signal mnemonics for J1.

The MVME712M transition module (

) and P2 adapter board are 

used in conjunction with the MVME2603/2604 base board.

The features of the MVME712M include:

❏

A parallel printer port

❏

An Ethernet interface supporting AUI connections

❏

One synchronous/asynchronous, and three asynchronous only, 
EIA-232-D multiprotocol serial ports

❏

An SCSI interface (via P2 adapter) for connection to both internal 
and external devices

❏

Socket-mounted SCSI terminating resistors for end-of-cable or 
middle-of-cable configurations

❏

Provision for modem connection

❏

Green LED for SCSI terminator power; yellow LED for Ethernet 
transceiver power

The features of the P2 adapter board include:

❏

A 50-pin connector for SCSI cabling to the MVME712M and/or to 
other SCSI devices
