Models 2/20, 4/40, and 6/60)
SCSI Cable Connections
NOTE Refer to “Fibre Channel Installation and Connections” on page 2-32 if the
library is configured with Fibre Channel.
Connect the library as follows (refer to Figure 2-20 through Figure 2-22):
1. Properly power off all peripheral devices connected to the host
computer.
If the host computer is connected to a network, check with the system
administrator before turning off power.
2. Power off the host.
3. Connect a 68-pin SCSI cable from the top connector of the library
controller to the host.
CAUTION Use SCSI cables and HVDS differential terminators for high-voltage
SCSI interfaces. Use SCSI cables and LVDS differential terminators for
low-voltage SCSI interfaces. The label on the library controller indicates
high or low voltage.
4. Connect a jumper cable from the bottom connector of the library
controller to the first (left) drive module. Daisy-chain that drive
module to the second (right) drive module. For single-level libraries,
skip to step 6.
5. For multi-level libraries:
a. Daisy-chain the drive modules on each level by connecting a
jumper cable from the left drive module to the right drive module.
b. Connect a SCSI cable from the left drive module to the host.
