VF2-350-SCW-RHD Introduction
The VF2-350-SCW-RHD has been designed to provide a complete disk drive subsystem which is mechanically compati-
ble with the VMEbus. It has been designed specifically to interface with VMEbus processors with an embedded
Fast/Wide SCSI Host Adapter. Together with the processor, a complete system can be installed in only three standard
VMEbus system slots. The VF2-350-SCW-RHD provides a removable 3.5 inch low profile disk in a 2 slot 6U VME mod-
ule making it very convenient to have removable data storage. The drive used in the VF2-350-SCW-RHD was chosen for
compatibility, ruggedness and reliability. The Fast Wide SCSI-2 bus can be connected to the module via the front panel
68 pin Wide SCSI connector or via the P2 connector, with pins used in the A and C rows of P2 for the SCSI data, control
and parity signals.

Features and
Specifications

Scope
This chapter describes the overall features and specifications of the VF2-350-SCW-RHD.
Features
The VF2-350-SCW-RHD incorporates one very compact removable winchester disk drive within a single module. The
hard disk drive is a high-performance winchester type with embedded disk drive control electronics. This microproces-
sor controlled embedded controller is on the hard disk and is compatible with ANSI X3.131-1986 SCSI commands.
The hard drive is a very high performer, with a 1-to-1 interleave and an average track-to-track access times of less than
10 milliseconds. It incorporates an embedded cache buffer which is operated in “look ahead” mode, providing buffering
for sequential sector operations. The hard drive has been carefully packaged with suitable control and power distribu-
tion connectors for direct attachment to single board computers in the VME chassis or to external devices.
WIDE SCSI Interface Description
In order to provide a method of embedding the disk drive control electronics within the hard disk drive, several disk
drive manufacturers jointly defined an interface specification. This specification for the Small Computer System Inter-
face has become known throughout the industry as “SCSI”. Basically, the SCSI interface consists of the required
address, data and control signals from a wide SCSI Host Adapter. Since a goal of the specification is to allow the disk
drive to be connected via standard cable, the specification required buffering of all signals so that the drive could be
mounted a suitable distance from the board interface. This distance, however, is limited to eighteen feet. The specifi-
cation provides all signals via a 68-pin header connector for use with standard 68 conductor cable and connectors.
Table 2-2 is a description of the wide SCSI-2 pin definition. The direction indicated is relative to the host.

Configuration, Installation,
and Operation

This page intentionally left blank.

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.
Configuration, Installation, and Operation 3-3

Drive Software Configuration
Initially you will need to run a device setup program in order to configure the software and hardware to properly recognize
the drives on the VF2-350-SCW-RHD. You should consult the host/processor manual and/or operating system manuals
for a description of the utility required to properly format and use your mass storage subsystem.
Hard Drive Software Configuration
The hard disk drive can be installed as SCSI unit 0-15. The disk drive characteristics are described in detail in Chapter 4.
It operates using the Fast/Wide SCSI-2 interface and has to be configured by the host operating system software for
proper operation.
Terminator Power
Terminator power for the drives can be jumpered to route the Terminator Power from different sources. A jumper installed
at TERMPWR C to BRD supplies power from the on board circuitry. Jumper TERMPWR C to HOST allows the SCSI bus
Host to supply the Terminator Power to the unit and the P2 connector if they are so configured.(See Figure 1-2)
Termination
The active termination required for the SCSI-2 bus is on the VF2 module. The SensiTermTM circuitry will automatically
configure the termination for the SCSI bus. It determines if the SCSI bus signals are received from the P2 connector or
from the 68 pin Micro-D connector on the front panel and sets the termination at the correct end of the SCSI bus. If the
module is in the middle of a SCSI bus route, the SensiTermTM circuitry automatically disables all on board termination.
Operation
The VF2-350-SCW-RHD module has a removable disk drive carrier/drive module installed from the factory. The front
panel keylock performs several functions. When the keylock is moved to the "Locked" (full counterclockwise)position, it
physically locks the hard disk carrier into the module. It also applies power to the disk drive using a "Soft Power" circuit.
This circuit applies voltage to the disk drive to activate its circuitry and then ramps the current to the drive to prevent a
high in rush current condition. While the disk drive is spinning to operating speed, the ID LED indicator flashes the
selected ID number. When the drive has reached operating speed and is ready to be accessed, the ID LED indicator
stops flashing. When the keylock is moved to the "Unlock" position, the ID LED flashes to notify the operator that the disk
is going into a non-operating mode. When the drive has spun down and can be safely removed from the module, the ID
LED shows a "u" to indicate that the drive is unlocked, spun down and safe to be removed.
Once the VF2-350-SCW-RHD has been configured properly and the software has been set up, operation is identical to
that of a standard SCSI storage subsystem. No specialized software is required.
