Hardware Preparation and Installation

Remote Status and Control

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-row14-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.

Table 4-1in Chapter 4, Connector Pin Assignments lists the pin numbers and signal mnemonics for J1.

MVME712M Transition Module Preparation

The MVME712M transition module (Figure 1-3) 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
