Library Installation

Connecting and Powering on the Library

Chapter 1 1-27

Getting Started

SCSI Cable Connections

NOTE Refer to “Fibre Channel Cable Connections” on page 1-33 if the library is

configured with Fibre Channel.

This section illustrates a standard SCSI configuration that produces a

high level of data storage performance (one SCSI host bus adapter card

for each drive in the library with the library controller daisy-chained to

the first drive). HP supports up to two drives per SCSI host bus adapter

but recommends only one drive per bus. If compression is used when

attaching two drives per bus, keep in mind the combined transfer rate of

the drives must not exceed the throughput of the host bus adapter used.

Connect the library as follows (refer to Figure 1-18 through Figure 1-20):

1. Properly power off all peripheral devices connected to the host

computer.

2. Power off the host. If the host is connected to a network, check with

the system administrator before turning off power.

3. Connect a 68-pin jumper cable from the top connector of the library

controller to the left drive module (drive module 1).

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 the appropriate 68-pin SCSI terminator to the bottom

connector on the library’s controller card.

5. Connect a 68-pin SCSI cable from a host SCSI card to each drive

module. Add the appropriate terminators to the remaining SCSI

connectors.

6. Connect the remote management card (see “Using the Remote

Management Card” on page 3-9).
