A two-drive DLT library uses both SCSI buses, so only one two-drive DLT library may be connected to one HBA. An MO library may be connected to each SCSI bus on a bridge, so two MO libraries (maximum) may be connected to one HBA. 2- 6 Chapter 2

Setting Up the Fibre Bridge
Installing Cables
Installing Cables
The Fibre Bridge can be used in either basic or expanded system
configurations. This section provides the steps to install cables in both
configurations.
NOTE
The following section explains overall configuration cabling. For
complete installation procedures, refer to the INSTALL subdirectory on
the CD-ROM shipped with the bridge.
Fibre Bridge Connection, Basic Configuration
Example (DLT and MO Libraries)
CAUTION
Be sure all devices in the configuration have been turned off and
disconnected from the power source before making any connections.
Failure to disconnect all power could result in damage to the devices.
1.
Properly shut down all peripheral devices that will be connected to
the Fibre Bridge, including the host. If the host computer is connected
to a network, check with the system administrator before switching
off power.
2.
Connect the SCSI cable from bus 1 on the Fibre Bridge to bus 1 on the
library.
For a two-
drive
DLT library, connect a SCSI cable from bus 2 on the
Fibre Bridge to bus 2 on the library.
For a two-
bus
MO library, connect a SCSI cable from bus 2 on the
Fibre Bridge to bus 2 on the library.
NOTE
A basic, point-to-point configuration is
“
One HBA to one bridge to one or
two SCSI buses.
”
A two-drive DLT library uses both SCSI buses, so only one two-drive
DLT library may be connected to one HBA.
An MO library may be connected to each SCSI bus on a bridge, so two
MO libraries (maximum) may be connected to one HBA.
