Hi All,
Just wondering if the 3845 supports OIR ( hot swap). I am looking at a link which says
http://www.cisco.com/en/US/docs/routers/access/3800/hardware/installation/guide/38netmod.html#wp1008236
Caution 
The Cisco 3845 and 3845-NOVPN router supports OIR with similar modules only. If you remove a network module, along with any installed WAN or voice interface cards, install another module and card combination exactly like it.
Caution 
Cisco 3800 series routers do not support OIR (hot swap) of interface cards inserted directly into router slots. You must turn off the router before installing or removing an interface card.
....your advise would be appreciated as I need to plug in a HWIC-1GE-SFP into a production 3845.
Regards
Kishore
