Installation 17
• Before you remove the drive from the antistatic bag, touch a metal or grounded
surface to discharge any static electricity buildup from your body.
• Always lay the drive either on top of the antistatic bag or place it inside of the
bag to reduce the chance of damage from static discharge.
• Install HVD drives only in an HVD environment, Fibre Channel drives only in a
Fibre Channel environment, and LVD drives only in an LVD environment. Do not
mix HVD and LVD devices on the same SCSI bus. Look at the label above the
drive’s SCSI connector to determine if the drive is an HVD or an LVD model
(see examples below:

• Due to the speed of the Viper 200 drive, it is recommended that a maximum of
two Viper drives be connected to one host SCSI adapter. In a switched Fibre
Channel environment, the maximum number of drives that can be used
simultaneously depends on the bandwidth of the loop.
Installing an internal HVD or LVD Viper drive
This section describes the steps necessary to install an internal Viper 200 drive with
an Ultra2 SCSI LVD or Ultra SCSI HVD interface. For instructions on installing a
Fibre Channel drive, see page 23. For instructions on installing an external HVD or
LVD drive, see page 27.
1. Configuring an internal HVD or LVD drive
Before you install the tape drive in your computer, you may need to configure the
drive’s SCSI ID and other drive features. Jumpers located on the back of the drive
(near the left edge) are used to configure the SCSI ID and to enable termination
power.
Default settings
The default drive settings for the Ultra2 SCSI LVD and Ultra SCSI HVD Viper 200
drives are:
• SCSI ID 6
• Termination power disabled
(configuration may vary if purchased as a component of a Library).
If these default settings are appropriate for your needs, skip ahead to “Mounting an
internal Viper 200.”
Jumper settings
Configuration jumpers on the back of the Parallel SCSI drive control the drive’s SCSI
ID and SCSI termination power. The jumpers can also be used for remote SCSI
address selection. Figure 3 shows the locations of the jumper blocks for the internal
Viper 200.
