I pulled out HWIC card from a Cisco 3845 router and inserted it back while the switch is powered ON. I didn’t realise this is not hot swappable while doing that. The router rebooted itself with bus error “System returned to ROM by bus error at PC 0x0, address 0x0”. After the router is rebooted I couldn’t see the HWIC ports coming up. They are showing as “Serial0/0/1 is down, line protocol is down”. Could some one help me how I can fix this?
