Host Interfaces

The 9840 Tape Drive interfaces with Fibre Channel and SCSI hosts. The drive
ships with a factory installed interface card that is not to be changed in the field
or at customer sites.

•

The Fibre-Channel (FC) configuration of the 9840 Tape Drive has dual fiber-
optic ports to allow for point-to-point, arbitrated-loop (including redundant-
loop), and fabric topology. The FC interface for the 9840 Tape Drive uses
Fibre Channel protocol for SCSI (FCP-2).

•

The SCSI interface card (ASIA—Application Specific Interface Adapter) has
only one port. The card can be programmed to different interface
specifications in the field from the drive operator panel.

Configurations

The drive is usually a component in a subsystem assembly that consists of the
drive, a power supply, and enclosures or trays, depending on the installation
environment. Refer to

Table 1-1

for specific 9840 Tape Drive configurations and

interfaces.

Depending on the installation, the drive and power supply may be separated or
combined in an assembly. The FRUs (drive and power supply) may be attached
to a tray or installed within an enclosure.
