Cisco 7604 rebooting

Unanswered Question
Jun 26th, 2008

Hi guys,

We have a cisco 7604 running ios 12.2(18)IXB1. The router has rebooted and "show version" shows "System returned to ROM by s/w reset (SP by power-on)".

Does anyone know what this mean?

I have this problem too.

You need to recover the from rommon. In rommon mode, please capture the following;


rommon>dir bootflash:

rommon>dir disk0:


rommon>dir disk1:

Please go to this link below in recovering the Sup720 in rommon mode. The IOS might be

corrupted that is why you keep on going to the rommon mode.
