VMIVME-7455 Single-Slot VMEbus CD-ROM Drive Module
Installation of the VMIVME-7455 with the VMIVME-7696
The VMIVME-7696 is a two board set that offers P2 I/O connections for the SCSI, IDE
and Floppy interfaces. The VMIVME-7696 SCSI signals are located on the Daughter
card ‘P2 connector’, with the IDE and Floppy interface on the Motherboard ‘P2
connector’. The VMIVME-7696 is compatible with VMIC’s VMIACC-0561 (VMEbus
P2 transition board), for routing the SCSI signals to a standard 68-pin Ultra-SCSI-2
connector. The VMIVME-7696 utilizes VMIC Model Number VMIVME-VMXC-7
which is a different cable from the one used by other CPU products. The added length
between the connector intended for the CPU’s motherboard and the middle connector
allows routing of the cable when the VMIACC-0561 is installed. The following is the
procedure used to install the VMIVME-7696 and the VMIVME-7455:
1. Insert the VMIVME-7696 CPU board into the desired slot of the VMEbus chassis.
2. Insert the VMIVME-7455 and the optional VMIVME-7452 into the desired slots
of the VMEbus chassis.
3. Connect the 64-conductor cable assembly to the extended pins of the P2
connectors located on the rear of the backplane.
3a. The cable must be installed into the slot occupied by the CPU’s
motherboard.
3b. The other end of the cable must be installed into the slot occupied by the
VMIVME-7455.
3c. If a VMIVME-7452 is to be used, install the connector located in the
middle of the 64-conductor cable assembly into the corresponding slot.
Figure 8 on page 13 illustrates the installation of the VMIVME-7696 with the
VMIVME-7455, and the optional VMIVME-7452.

The VMIVME-7696, -7455, and the -7452 do not have to be in consecutive slots in the
VMEbus chassis.
