Cat 4000 hot-swap sup modules?

Is it possible to hot swap a SupIV for a 4232 in a Cat4k? I know the
port architecture is different, but, if we have Cat4ks+4232s in hsrp
mode can we leave the chassis powered on while swapping so that all the
switch modules can be active?

I don't have a 4000 series, but some research I was doing on the
series last week indicated that hot swapping of the supervisors is
supported [or at least it is in a 4500 series; I wasn't looking
for differences between the 4000 and 4500's.] The documentation indicated
that when the supervisor is offline, no routing will take place
and no forwarding will take place between interface cards.

I don't have time to track down exact references, but see for example
http://www.cisco.com/en/US/products...allation_guide09186a00800ead68.html#wp1035802
which indicates that the Access Gateway Module may be hot-swapped
[but not any WIC's, VIC's, VWIC's or other line interfaces.]

 

Yeah, I saw the doc about the AGM too. Thanks

AFAIK, modules in 4000/4500 is hot-swappable, but I don't think it's going to
help. Since all switching is done by Supervisor as soon as you remove it no
traffic is going to pass through.

With best regards,

The 4500 supports dCEF, so while the Supervisor is out, it should
still be able to switch existing flows that are entirely within
the same line card.

That's news to me. URL?
