one of my client is facing problem in module 2 of 4506 switch with supIV(image is cat4000-i5k91s-mz.122-20.EWA.bin). the logg file is attached. it gives:
Nov 17 01:37:48.719: %C4K_GBICMAN-3-S2WERROR: S2w bus error while looking for changed gbics on port Gi2/2: S2wErrorNoAckDevAddress
The module remains stuck(hang)for an hour and resumes working normally after that. the problem is intermittent. so i m not able to find the soltion for that.
