Dear Team,
we replaced a SUP720 installed in a Cisco 7206vxr because after a switchover it has been in ROMMON.
After the hot swap of the board the device restarted, i suppose that it is due by a bug , with the combination of hardware (5.2) and release (IOS 12.2 (33) SR) described in this link http://www.cisco.com/en/US/ts/fn/620/ fn62606.html. in short can happen that the insertion of a new SUP go into ROMMON both because of an Ethernet Out Band Channel jamming.
Then forcing the console to boot the router has performed the self-SSO sync correctly, but during the test force switch-over has come back the initial problem, that is, the SUP is active instead of going to standby remains in ROMMON and restart it is necessary to force the boot from the console.
Becuase the new card installed has a newer hardware (5.9) I decided to keep it in order to avoid a recurrence of this bug,
I would like to have your support to decide if it is necessary to swap also the other supervisor with hw revision 5.2 .
Also I would like your help to analysis why the SUP rem goes ROMMON after the switchover, whether forced or incidental.
Regards
HDDIB
