Troubleshooting SFP+ Cables Problems


SOPTO SFP+ 10 Gb/s Active and Passive Cable Assemblies are compatible with any switch or server that includes MSA compliant SFP+ ports, unless that product requires active cable assemblies or requires a proprietary code in the SFP+ DAC cable assembly.  Referring to the table on SFP+ Copper Cable Assemblies Compatibility, the known switches that will not work with Panduit SFP+ DAC cable assemblies are: Cisco Catalyst Series (These can be enabled through the command line interface (CLI)), HP (Procurve switches), and Brocade (8000 FCoE, VDX6730, and Iron series switches).  Panduit can provide a custom cable programmed for the VDX6730, please contact us for details.


There are some instances when passive SFP+ cables assemblies will not work, where the port requires an active SFP+ cable assembly.  Known CNA cards that require active SFP+ cable assemblies include: Brocade (1010/1020 CNA) and QLogic (QLE - 8xxx- SR CNA).  The EMC VNX Series Unified Storage Systems also requires active SFP+ cable assemblies.

If using SFP+ DAC cable assemblies between equipment that should be open, and the link is not working, a quick check can be performed by plugging in a different SFP+ cable assembly between the same two ports.  If the link does come up, it is likely a problem with the first SFP+ cable assembly.  If the link does not come up, it is likely a problem with the configuration of the ports or incompatibility between server and switch.
