Connecting to a Host
The 2 Gb TP9100 supports only Fibre Channel optical connectivity to the front-end host

Note: Copper connections to hosts and/or switches are not supported for either RAID
or JBOD enclosures.
A pair of copper cables is packaged with 2 Gb TP9100 JBOD enclosures. These cables are
manufactured with copper SFPs on each end of the cable. Use the copper cable/SFP
assembly to connect JBOD enclosures used either as capacity expansion enclosures for a
RAID system or to connect cascaded JBOD enclosures. When the JBOD enclosure is used
