Environment
  • Summit X670V-48t
  • Summit X460G2-48p-10G4
  • Summit Stack
  • EXOS 15.3.2.11-patch1-2
  • EXOS 15.6.2.12
Cause
The i2c warning messages are generated due to the inter-integrated circuit bus becoming unresponsive. A possible cause of an unresponsive i2c bus is a faulty connection between the connected VIM and switch.
Resolution
Re-seat the VIM4-40G4X that is seated in the switch exhibiting the kernel card warning messages.
Additional notes
Note that the VIM module is not hot-swappable, so the switch must be powered down prior to the re-seat.
