Network Interface Cables and Connectors

The following table lists cables used for connecting QIPs and direct-attach
tape drives to the host network.
Interface Type
Direct-attach tape
drives
Quad Interface
Processors (QIPS)
a. Spectra Logic recommends using quad-rate SFPs with all E-QIPs and F-QIPs.
b. If you have a 4 Gb F-QIP, you must use a 4Gb SFPs in the ports.
c. Copper RJ-45 SFPs are supported on the G3 E-QIP. Copper SFPs are designed for use with Gigabit Ethernet connections only and are
not for use with Fibre Channel connections.
The minimum cable requirements when using the copper SFPs is CAT5e. CAT6 cable is highly recommended for distances greater
than 10 feet.

Fibre Channel Interface

The Fibre Channel interface in the F-QIPs and direct-attach tape drives
support the Fibre Channel Protocol (FCP).
F-QIPs The Fibre Channel QIP (F-QIP) provides a Fibre-Channel-to-SCSI
interface between the host and the library's SCSI tape drives or RXT drives.
Each of the two Fibre Channel ports on an F-QIP provides access to all or
any of the four tape drives associated with the F-QIP.
Direct-Attach Fibre Channel Tape Drives Each direct-attach Fibre Channel
tape drive has a single optical fiber port. Robot control commands from the
host are routed to the transporter through LUN 1 for one of the tape drives
in the partition. The tape drive reports the transporter as "SPECTRA
PYTHON" on LUN 1. LUN 0 is the tape drive itself.
