Troubleshooting SFP+ Problems

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 page 1, 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 Panduit for details.

There are some instances when passive SFP+ cables assemblies will not work, where the ports require 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.

SFP+ Cables and Cisco Technical Assistance Center (TAC)
Panduit is the only 3
rd
party vendor currently Cisco certified on the N2K and the N5K. This means Panduit SFP+
DAC cable assemblies can be used and still receive support from Cisco TAC. When using Panduit SFP+ DAC
passive cables the “NON-CISCO_TRANSCEIVER” message should not be received on the N2K and N5K. Panduit
passive cables the “NON-CISCO_TRANSCEIVER” message should not be received on the N2K and N5K. Panduit
is compatible with the N7K and UCS, but is not certified with the N7K or UCS.
Support from Cisco TAC requires the use of Cisco certified cables. To receive assistance from TAC regarding a
link error, it must be confirmed that Cisco certified cables are being used. If non-certified cables are being used,
they must first be replaced with Cisco certified cables before troubleshooting can begin. With non-certified
cables, an informational message stating “NON-CISCO_TRANSCEIVER: Non-Cisco transceiver on
link error, it must be confirmed that Cisco certified cables are being used. If non-certified cables are being used,
they must first be replaced with Cisco certified cables before troubleshooting can begin. With non-certified
cables, an informational message stating “NON-CISCO_TRANSCEIVER: Non-Cisco transceiver on
interface
” is received on the N2K, N5K, and N7K series switches. Note that even with these informational
messages, all compliant SFP+ DAC cable assemblies will work. (Note: N7K will be open with OS revision 5.2.1
due out in the fourth quarter of 2012). The message “IF_UNSUPPORTED_TRANSCEIVER: Transceiver on
due out in the fourth quarter of 2012). The message “IF_UNSUPPORTED_TRANSCEIVER: Transceiver on
interface *** is not supported
” is received, it means that support for 3
rd
party SFP+ must be enabled
via the CLI.
