As per previous posting, if you do not mind the redundant power supply to be
external you can do it on any switch I can think about. I had done it over
the years with 2924xl, 3524xl, 3550 and worked good every time (obviously
internal is better). Make sure you check RPS for a small switch matches
your availability requirements. Some of the allow for fully redundant DC
power, some allow for DC to back up AC, some can provide DC backup to
multiple devices as long as only one device actually uses it at any given
time. Some small switches reboot when power goes from AC to DC and vice
versa.
If you want it inbuilt the 4500/4000 is the smallest currently available
model I think. Earlier models of 4000 platform had 2+1 redundancy and I did
not like it at all.
Best regards,
Alexei

All the modular catalysts have redundant options. Even with the lower
end you can get redundancy but you have to buy a seperate component, see
Cisco RPS.
