Cabling requirements
You should use the Fibre Channel cables shipped with your PFR600/E when making
connections.
Optical cables must meet the appropriate 2-Gbit FC-AL loop standards. You must use
this type of cable to connect PFR600E expansion chassis to the PFR600 controller.
Any copper cables you use must meet the appropriate standards for 1-Gbit FC-AL loops.
Such cables are fully shielded, twin-axial, full-duplex cables with DB-9 connectors.
Cables greater than 10 meters must be equalized; cables equal to or less than 10 meters
do not need to be equalized. Do not use copper cables longer than 15 meters for any Fibre
Channel connection in a Profile system.
PFR600 and PFR600E interconnections should maintain LBB consistency. That is, one
FC loop should connect the PFR600’s RAID Controller A and each PFR600E’s LBB A.
The other FC loop should connect the PFR600E’s RAID Controller B and each
PFR600E’s LBB B.
Do not leave an unused (that is, dangling) cable connected to a Fibre Channel port
because it may cause excess noise on the loop.
