(MP) tape used with previous generations of Exabyte products. The Mammoth-LT tape drive is available as an internal model that can be installed into an enclosure (shown on the right) or as a tabletop model housed in its own enclosure (shown on the left). -
Page 8: Available Scsi Configurations
Available SCSI configurations 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 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. -
Page 9: Installing The Tape Drive
Installing the tape drive This section describes how to install the 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 10 Installing the tape drive 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: Exabyte M ammoth-LT...
- Page 11 Installing the tape drive Step 1 – Set the SCSI ID To set the SCSI ID, remove and reposition the jumpers to obtain the desired ID. (If necessary, use a pair of flat-nose pliers to remove the jumpers.) The following figures show how to position the jumpers for narrow and wide SCSI configurations.
- Page 12 Wide SCSI configuration (SCSI IDs 0–15): If you need additional jumpers, use 2 mm mini jumpers for wide SCSI (AMP part number 382575-2). Note: You can also set the SCSI ID by removing the jumpers and connecting your own remote switch. Exabyte M ammoth-LT...
- Page 13 Installing the tape drive 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.
- Page 14 Use one of the terminator types listed in the following table. Important Exabyte recommends using active termination. Exabyte testing has shown that older passive termination does not provide rising edge transitions that are fast or clean enough at fast SCSI speeds.
- Page 15 Installing the tape drive 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: ...
- Page 16 The tape drive performs its power-on self-test in about 30 seconds. 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. Exabyte M ammoth-LT...
- Page 17 Installing the tape drive 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.
- Page 18 Ensure that no objects such as screw heads, cables, or adjacent 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. Exabyte M ammoth-LT...

Installing the tape drive 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 To set the SCSI ID for the tape drive, use a pen or other fine-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). - Page 20 2. Affix the pads to 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). Exabyte M ammoth-LT...
- Page 21 Installing the tape drive CAUTION If you want to position the tape drive on its side, you must place the pads on the right side. Otherwise, the air flow vents will be blocked and the enclosed tape drive will overheat. Step 3 –...

Page 27: Selecting Appropriate Data Cartridges
AME cartridges are available in lengths of 22m and 125m. Important The Mammoth-LT tape drive does not support the Exatape 170m AME tape length. If you try to insert this tape, the tape drive automatically ejects it. -
Page 28: Loading Data Cartridges
Operating the tape drive Important Mammoth-LT can read data written on metal particle tape, but it cannot write to this type of tape. Loading data cartridges To load a cartridge: 1. Make sure the tape drive is ready to accept a cartridge (all LEDs are off). -

Operating the tape drive 3. Insert the cartridge as shown in the following figure. The tape drive loads the tape in approximately 20 seconds. When the middle LED is on, the tape drive is ready for read and write operations. Unloading data cartridges To unload a cartridge, press the unload button. -
Page 30: Resetting The Tape Drive
To clean the tape drive, insert an Exabyte Mammoth 8mm Cleaning Cartridge (or a cleaning cartridge approved by Exabyte for use with Mammoth-LT). When finished, the tape drive turns off the top LED and ejects the cleaning cartridge. Exabyte M ammoth-LT... -
