Initial Public Release
68- assembly is manufactured with a new ASIC - TAN phased to production thru ECO EA527154
Some Nexus N56-M24UP2Q modules are incompatible with certain Nexus N5K-C56128P chassis and fail to change to online status when plugged into the chassis.
The N56-M24UPQ module and N5K-C56128P chassis underwent a hardware revision in Dec 2015. Although low in occurrence, certain N56-M24UPQ modules released after this revision are incompatible with N5K-C56128P chassis released prior to the revision.
N56-M24UP2Q modules with top assembly number (TAN) 68-5671-01 are not compatible with N5K-C56128P chassis that have TAN 68-5193-02 or 68-5193-03.
N56-M24UP2Q modules with TAN other than 68-5671-01 are compatible with any hardware version of the N5K-C56128P chassis.
Cisco has determined the root cause of the problem and identified a fix which was implemented through a minor hardware revision on the modules. This fix enables the N56-M24UP2Q modules to be compatible with any version of the N5K-C56128P chassis.
This error can be seen upon module insertion:
Module X insertion failed. Module may not be seated properly or of wrong type. Remove module, ensure correct type and re-insert after five or more seconds.
If the hardware shows an incompatible configuration as described in the "Background" section, request a replacement N56-M24UPQ module via the form in the "Upgrade Program" section.
If the hardware shows a compatible configuration, the error is not due to Cisco bug ID CSCut89127
and the Upgrade Program should not be leveraged.
Refer to the "How to Identify Hardware Levels" section for instructions on how to view the TAN versions of the module and chassis.
