Hi,
I just upgraded the IOS of 4948-10GE switch to cat4500-entservicesk9-mz.122-54.SG.bin, but during boot process I got this exception :
UNHANDLED ROMMON EXCEPTION at PC=0453ab5c
Vector=00000100 MSR=02029230 LR=0453ab24
MCSR=00000000
CISR0=00000000 CISR1=40000000

Hi Tonny,
Switch needs a ROMMON upgrade to boot this image. Current ROMMON Version: ROM: 12.2(31r)SGA1 The Recommended ROMMON version: 12.2(31r)SG3 This is documented in Table 4 "Catalyst 4900 Series Switches, Recommended ROMMON Release, and Promupgrade Programs " here: http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/release/note/OL_9592.html#wp305142
HTH

Thank you for the fast reply, I upgraded ROMMON to 12.2(31r)SG3, but this didn't helped very much, the same issue persist.

Tonny,
Before I dig this can you please upgrade the rom to
12.2(31r)SGA4.. as this issue as been reported as bug. Once this is done I can proceed with further looking into this.
