Phoenix International VF2-350-SCW-RHD, Technical Information

Page: 17 / 22

Scope
This chapter describes how to configure, install and operate the VF2-350-SCW-RHD mass storage subsystem module.
Drive Hardware Configuration
The drives on the VF2-350-SCW-RHD can be configured for normal operation as SCSI units 0-15 by setting the front
panel switches with a small screwdriver.(See Figure 1-1) The particular configuration of the Unit ID's required depends
upon the software and the application operating system.
Hard Disk Drive Hardware Configuration
The hard drive can be set so that it is activated by the SCSI unit 0-15 ID, as is required to maintain compatibility with the
SCSI software. The hard drive installed on the VF2-350-SCW-RHD utilizes the Fast/Wide SCSI-2 interface. It is possible
to connect another type of SCSI device via the interface cable and to connect 14 other units to the SCSI interface if need-
ed. (See Fig. 1-1) Please call Phoenix International Customer Support if you need assistance.
Considerations For Installation
There are several considerations before installing the VF2-350-SCW-RHD into your system.
VMEbus Slot Requirements
The VF2-350-SCW-RHD requires two adjacent slots in a standard VMEbus 6U card cage. Since the drives are mounted
on an aluminum panel, this could potentially cause a shorting problem. If you are going to have a VMEbus card located
in the next adjacent slot, you should carefully check it to make sure that no leads are likely to touch the VF2-350-SCW-
RHD.
VMEbus Backplane Configuration
The VMEbus P1 connector supplies all operating power to the VF2-350-SCW-RHD and shunts the daisy-chain signals on
the P1 connector. However, no other VME signals are connected on board. Therefore, you must check your VMEbus
backplane for all daisy-chain signals continuity at the two slot positions occupied by the VF2-350-SCW-RHD.
Power Supply Requirements
Make sure that your VMEbus power supply has adequate capabilities to support the operation of the VF2-350-SCW-RHD
when it is installed with all other cards in your VMEbus system. Pay particular attention to the +12 volt power require-
ment. The specifications listed in Chapter 2 and Chapter 4 should be consulted for the maximum current requirements.
Your power supply must be capable of providing sufficient current for the hard disk drive motor to spin up during initial
operation (approximately 5 seconds).
Installing the VF2-350-SCW-RHD
Make sure that all power is removed from the backplane before inserting the boards. Prior to inserting the VF2-350-
SCW-RHD into the card cage, it is necessary to verify the cable connections to the SCSI host/processor. Once you have
connected and properly seated the associated cable assemblies, you should insert the host/processor into the VMEbus
card cage. Now install the VF2-350-SCW-RHD into the VME chassis and mate the P1 connector properly. The P2 con-
nector should also be aligned. Then connect the VF2-350-SCW-RHD to the SCSI host/processor with a 68 pin Micro-D
cable or via the P2 connector on the backplane with the proper Phoenix International adapter module.
