It may be one of these. You may ignore, if you dont see any alert/alarms for high temperature :


CSCsi06813    WS-X6724-SFP/DFC3B may report EARL inlet temperature higher than outlet

CSCsi06811    WS-X6724-SFP/CFC may report inlet temperature higher than outlet

Thank you


but It's not WS-X6724.  actually it is WS-X6816-10GE


I can't find out in bug search that module.


but i may assume that it is possible to occure that module.

  • Cisco Employee,

I checked further and it seems this LC is affected with another such issue with :


CSCuj78044    6716-10G (Hw ver 2.0) may report inlet temperature higher than outlet


Here both, both type ( 6716,6816) will see the issue. Fix for this bug is committed for 15.1(2)SY2 release ETA during Mar/Apr 2014.
