If the 2nd one will even come up, it will almost definitely come up in RPR mode instead of SSO. So you're going to take a hit on all your linecards when trying the switchover. (My guess is the other will get stuck in 'standby cold' state). If it were me I'd just take a downtime hit and replace them both at the same time. Ken

Following your recommendations, I am planning to replace my most important router with the new sup (RSP 720-3C) and re-use the WS-720-3B to implement dual-sup in the other routers. The idea is the follwong: Main Router 7609-S with dual-sup WS-720-3B (02) - Replace the stand-by sup (WS-720-3B) by one RSP 720-3C.( here the critical point, I will try to test in lab if I get all the resources) - Switchover to RSP 720-3C and then this sup become the active sup. - Replace the old WS-720-3B by one RSP 720-3C and at the end, to have one 7609-S with 02 RSP 720-3C Best Regards JC On Sun, Jul 17, 2011 at 2:17 PM, Gert Doering <[email protected]> wrote: > Hi, > > On Sun, Jul 17, 2011 at 01:38:16PM -0500, cisco-pe wrote: > > Is it possible to use two different supervisor in one 7609?
