Step 2. Checking the electrical outlets
Make sure that the electrical outlets are properly grounded.

Step 3. Determining the SCSI address
The SCSI address identifies the device to the bus and the system. Be careful not to
set two devices to the same SCSI address because this will cause errors. The
selected address sets the priority of the device on the bus. Tape drives are usually
slow devices, compared to hard disk drives, so a tape drives should be set to a
high priority to ensure that it gets access to the bus in a timely manner.
The host system has 16 available SCSI address settings. From highest to lowest, the
SCSI bus priority is as follows: Highest 7 6 5 4 3 2 1 0 15 14 13 12 11 10 9 8
Lowest.
Before you install the 87691VX Tape Autoloader, make sure that its SCSI address is
not being used by another device. The 87691VX Tape Autoloader is a wide (16 bit)
SCSI device and uses SCSI addresses from 0 through 15 (usually, address 7 is
reserved for the SCSI I/O controller).
Note: The 87691VX Tape Autoloader is supported only on an LVD SCSI bus.
To determine an unused SCSI address, you need the following information:
v The name and the port number of the host system SCSI I/O controller that you
v The SCSI address of that SCSI I/O controller
v The SCSI addresses of other devices that are connected to that SCSI I/O
