Notes

Welcome
Installation and Operation 1
Welcome
Congratulations on selecting the Exabyte®Mammoth-LT Tape
Drive. Your tape drive is a high-speed, high-capacity tape drive
designed to meet the growing demands for data storage in such
areas as enterprise-wide networks, data acquisition, image
processing, video-on-demand, and multimedia.
The tape drive transfers data at a rate of up to 4 megabytes per
secondwith2:1compression,andcanstoreupto28gigabytes(GB)
of compressed data on a single data cartridge. The tape drive uses
advanced metalevaporated (AME)tape, which providesagreater
capacity than the metal particle (MP) tape used with previous
generations of Exabyte products.
The Mammoth-LTtape drive is available as an internalmodelthat
can be installed into an enclosure (shown on the right) or as a
tabletop model housed in its own enclosure (shown on the left).

Available SCSI configurations

Exabyte Mammoth-LT
Available SCSI configurations
The Mammoth-LT tape drive is available in narrow,
singled-ended and wide, low-voltage differential (LVD) fast
SCSI-2 configurations.
The LVDtape driveusesan LVDinterface that isUltraandUltra2
SCSI compatible. The LVD interface allows the tape drive to be
placed on the same bus as Ultra and Ultra2 SCSI devices without
slowing the performance of these devices.

Installation and Operation 3
Installing the tape drive
Thissection describeshowto installthe tape drive in an enclosure.
If you have the internal model of the Mammoth-LT tape drive,
follow the instructions below. If you have the Mammoth-LT
tabletop model, follow the instructions beginning on page 13.
Installing the internal model in an enclosure
ESD protection
Protect the tape drive from electrostatic discharge (ESD) by
following these precautions:
Use an antistatic mat and wristband, if possible.
Leave the tape drive in its packaging until you are ready to
install it.
Touch a known grounded surface before handling the tape
drive.
Do not place the tape drive on a metallic surface.

Location of components
When installing the tape drive, refer to the following figures for
the location of back-panel components.
Narrow SCSI configuration:
Wide SCSI configuration:

Installing the tape drive
Installation and Operation 5
Step 1 – Set the SCSI ID
To set the SCSI ID, remove and reposition the jumpers to obtain
thedesiredID.(Ifnecessary,useapairofflat-noseplierstoremove
the jumpers.)
The following figures show how to position the jumpers for
narrow and wide SCSI configurations.
Narrow SCSI configuration (SCSI IDs 0–7):
If you need additional jumpers, use 0.1-inch jumpers for narrow
SCSI (AMP part number 531220-2).

Wide SCSI configuration (SCSI IDs 0–15):
If you need additionaljumpers, use 2 mm mini jumpers forwide
SCSI (AMP part number 382575-2).
Note: You can alsoset the SCSI IDby removing the jumpersand
connecting your own remote switch.

Installing the tape drive
Installation and Operation 7
Step 2 – Connect the drive to the SCSI bus
Before connecting the tape drive to the SCSI bus, be aware of the
following:
You can connect single-ended and LVD SCSI tape drives to
the same SCSI bus. Be aware that mixing the two types of
devices will result in all devices on the bus operating as
single-ended devices.
The LVD tape drive uses an LVD interface that is Ultra and
Ultra2 SCSI compatible. The LVD interface allows the tape
drive to be placed on the same bus as Ultra and Ultra2 SCSI
devices without slowing the performance of these devices.
Do not connect a single-ended wide or LVD tape drive to an
HVD wide SCSI bus or your SCSI bus may hang.
The product ID label, shown below, displays the SCSI
configuration: LVD or SE.

Installing the tape drive
8
Exabyte Mammoth-LT
To connect the tape drive to the SCSI bus:
1. Connect an internal SCSI cable to the tape drive’s SCSI
connector and to the next SCSI device in the enclosure (for
example, a SCSI adapter card).
2. If the tape drive is the last device on the SCSI bus, you must
terminate the bus by installing a pass-through terminator on
the tape drive’s SCSI connector. Or, if there is an unused
connector at the end of the SCSI cable, you can terminate the
bus there.
Use one of the terminator types listed in the following table.
➤Important Exabyte recommends using active
termination. Exabyte testing hasshown that older
passive termination does not provide rising edge

speeds.
CAUTION
Connecting a single-ended wide or LVD wide
tape drive to an HVD wide SCSI bus may hang
your SCSI bus.

Step 3 – Connect ground
To protect the tape drive from electrostatic discharge (ESD), you
must attach the tape drive to the enclosure’s metal chassis (using
the mounting holes shown on page 11). If you need additional
chassis grounding, use either of the following methods:
Connect a 1/4-inch female spade connector to the ground tab
(shown below).
Connect an M3 ×0.5 ×6 mm self-tapping screw to the
grounding hole (shown below).
Note: The power supply returnsare connected to the chassis, so
you cannot isolate the logic common ground from the
chassis ground.

Step 4 – Connect power
To connect power to the tape drive:
1. Connect the enclosure’s internal power cable to the tape
drive’s power connector. (Use an AMP 1-480424-0 series or
equivalent female power connector.)
2. Power on the enclosure.

When the tape drive is ready to accept a cartridge, the LEDs turn
off.
➤Important Do not insert a cartridge into the
tape drive during the power-on self-test. The tape
drive will eject the cartridge.
CAUTION
Do not force the power cable into the tape
drive’s power connector. If the power cable is
upsidedownandyouforcetheconnection,you
may damage the drive when you power it on.

Installation and Operation 11
Step 5 – Mount the tape drive
The single-ended internal tape drive meets industry-standard,
5.25-inch half-high form factor mounting requirements. The LVD
internal tape drive is approximately 0.36 inches (9.2 mm) longer
than the standard form factor. The tape drive can be mounted
either horizontally or vertically and in a stationary or sliding
position.
As shown in the following figure, the main housing of the tape
drive includes three sets of four mounting holes to allow for a
number of mounting positions (two sets on the sides, set Aand
set B, and one set on the bottom, set C).

When mounting the tape drive, follow these guidelines:
Use oneset of mounting holes. (Use allfour holesin whichever
set you choose; do not use combinations of mounting holes
from different sets.)
Use M3 ×0.5 ×6 mm screws. For proper mounting, use the
correct screw length.
Ensure that no objects such asscrew heads, cables, oradjacent
devices are pressing against the frame.
Do not obstruct the ventilation slots on the bottom and at the
rear of the tape drive.
Allow sufficient space for accessing the tape drive’s front
panel controls.

Installing the tabletop model
Location of components
When installing the tabletop tape drive, refer to the following
figure for the location of back-panel components.
Step 1 – Set the SCSI ID
Tosetthe SCSIIDforthe tapedrive, useapen orotherfine-tipped
instrument to press the SCSI ID switch until the desired number
is displayed (0–7 for narrow SCSI or 0–15 for wide SCSI).
Note: Changes in the SCSI ID setting take effect after a normal
power-on or SCSI bus reset.

Step 2 – Install the orientation pads
The tabletop model includes adhesive pads that you must apply
to either the base or the right side, depending on how you plan
to position the tape drive. These pads protect the tape drive’s
surface and allow air to flow through the vents when the tape
drive is positioned on its side.
To install the pads:
1. Remove the backing from four pads. (Five pads are shipped
with the tape drive.)
2. Affix the padsto each corner, approximately 1/2-inch (1.3 cm)
from the sides.
For a horizontal orientation, place the pads on the bottom. For a
vertical orientation, place the pads on the right side (the side
with the external vents).
