VXA-2 FEATURES
This chapter describes the VXA-2 tape drive features and components. The
VXA-2 tape drive is designed for the storage and management of
enterprise-wide, mission-critical data. The VXA-2 tape drive is capable of
storing 80 gigabytes (GB) of native data on a 230-meter VXAtape. It can
transfer data at a sustained rate of 6 megabytes (MB) per second and is
backward compatible with the first-generation VXA-1 tape drive.
DRIVE MODELS AND INTERFACES
For simple and convenient system integration, the VXA-2 tape drive is
available in external and internal models. The internal VXA-2 complies with
industry standard 5.25-inch half-high form factor mounting requirements and
can be mounted horizontally or vertically. The external standalone model is
housed in an enclosure that allows the device to be placed horizontally or
vertically on a flat surface. External models can also be stacked. Neither model
can be installed upside down.
The internal model of the VXA-2 tape drive is available with either a wide,
Ultra2 SCSI low-voltage differential (LVD) interface or an IDE/ATAPI
interface. The external model of the tape drive is available with either a wide,
Ultra2 SCSI low-voltage differential (LVD) interface or a FireWire interface.

INSTALLATION
This chapter provides step-by-step instructions for installing the internal and
external models of the VXA-2 tape drive. The information in this chapter
expands on the instructions in the Quick Start guide that accompanied your
tape drive.
UNPACKING THE TAPE DRIVE
All Exabyte tape drives are tested, inspected, and carefully packaged at the
factory. However, because shipping damage can occur, you should follow the
steps below to unpack the tape drive:
1.
1.1.
1. Visually inspect the shipping container and notify your freight carrier
immediately if you see any damage.
2.
2.2.
2. Place the shipping container on a flat, clean, stable surface. If parts are
missing or the equipment is damaged, notify your supplier or Exabyte.
3.
3.3.
3. Save the original shipping container and packaging materials in case you
need to reship the tape drive.
INSTALLING THE TAPE DRIVE
The installation instructions for your tape drive depend on what model you
have:
4To install the internal LVD SCSI model of the tape drive, read “Installing the
Internal SCSI Tape Drive,” beginning on page 8.
4To install the internal IDE/ATAPI model of the tape drive, read “Installing
the Internal IDE/ATAPI Tape Drive,” beginning on page 13.
4To install the external LVD SCSI model of the tape drive, read “Installing the
External SCSI Tape Drive,” beginning on page 17.
4To install the external FireWire model of the tape drive, read “Installing the
External FireWire Tape Drive,” beginning on page 19.

8PRODUCT MANUAL 1009541
Chapter 2INSTALLATION
INSTALLING THE INTERNAL SCSI TAPE DRIVE
The internal tape drive complies with industry-standard, 5.25-inch half-high
form factor mounting requirements and can be mounted either horizontally or
vertically, but not upside down.
When installing the tape drive, refer to Figure 2-1 for the location of the
back-panel components on the SCSI tape drive.
Before You Begin
Before you begin hardware installation, do the following:
4Select your application software — To obtain information about which
software applications work with the tape drive, visit Exabyte’s web site
(www.exabyte.com). You can install the software application on the host
computer before or after you install the tape drive. However, if you install
the software first, you may need to reconfigure it for use with the tape drive.
4Install the SCSI host bus adapter card — Make certain the SCSI host bus
adapter card installed in the host computer is LVD and compatible with the
tape drive. Exabyte does not recommend connecting the tape drive to a RAID
controller.
4Protect the work area from ESD — Touch a known grounded surface to
discharge static electricity from your body and ensure that the work area is
free from conditions that could cause ESD.

Important To avoid SCSI bus hangs, do not connect the tape drive to an HVD
SCSI bus. To avoid performance problems, do not connect the
tape drive to a single-ended SCSI bus.

INSTALLING THE TAPE DRIVE
Set the SCSI ID and Term Power; connect the SCSI cable
1.
1.1.
1. Power down the computer system.
Turn off all devices attached to the computer in which you plan to install the
tape drive, then turn off the computer. Disconnect all power cables.
2.
2.2.
2. Prepare the drive bay.
Remove the drive bay’s cover plate according to the system manufacturer’s
instructions.
3.
3.3.
3. Set the SCSI ID and termination (term) power jumpers, if necessary.
a.
a.a.
a. The tape drive is shipped with a SCSI ID of 11. If another device on the
SCSI bus is already configured with this SCSI ID, you will need to change
the tape drive’s SCSI ID. Reposition the jumpers on the jumper block, as
shown in Figure 2-2, to select the desired ID. (If necessary, use flat-nose
pliers to remove the jumpers.) If you need an additional jumper, use a
2 mm jumper.
Alternatively, you can remove the jumpers and connect a cable (not
included) from a remote switch to the jumper block, then use the remote
switch to set the SCSI ID. The cable should use a connector equivalent to
Hirose Housing part number DF11-8DS-2C, 2.0MM 8CKT to connect to
the jumper block.
Important Each device on the SCSI bus must have a unique SCSI ID.

b.
b.b.
b. Set SCSI termination (term) power, if necessary.
You can use the auxiliary connector to enable the terminator power
signal. (The tape drive is shipped from the factory with termination
power disabled.) To enable termination power, place a jumper across the
far right pins on the auxiliary connector, as shown in Figure 2-3. Make
sure the jumper is firmly in place. Use a 2 mm jumper.
Note: To protect the tape drive components if term power is shorted, the
tape drive includes a self-resetting power fuse.
4.
4.4.
4. Provide additional grounding, if desired.
Attaching the tape drive to the enclosure protects the tape drive from ESD.
However, if you want additional chassis grounding for the tape drive, use
the grounding hole or grounding tab on the back panel (see Figure 2-1):
4Connect an M3 (0.25 in.) female spade connector from the host to the
tape drive’s grounding tab.
or
4Use an M3 ×0.5 mm ×4 mm machine screw to connect a grounding wire
to the grounding hole.
5.
5.5.
5. Connect the SCSI cable.
Connect one of the enclosure’s internal SCSI cables to the SCSI connector
on the back of the tape drive (see Figure 2-4). This cable must meet the
guidelines in “SCSI Cable Requirements,” beginning on page 47.
Note: If desired, you can mount the tape drive (see page 16) before you
connect the SCSI cable and the power cable to the back. However, if
the cables are difficult to access in the enclosure, you should extend
the cables out through the drive bay and connect them before
mounting the tape drive.

Caution Do not use a screw other than the type specified for attaching the grounding wire,
or you may damage the internal components.
