I just installed an RPS 2300 in a small branch office that has a pair of WS-C3560-24PS switches. There are two odd things I'm noticing:
1) When I do "show env rps", it shows the RPS detected but I don't get any information about it.
Switch#show env rps
SW Status RPS Name RPS Serial# RPS Port#
-- ------------- ---------------- ----------- ---------
1 Active <>
2) When the switch loses power it fails over to the RPS just fine, but does not fail back to regular power automatically. I have to unplug the RPS.
I've installed same model RPS with a pair of 3750-Es switches, and in that case, "show env rps" from the switch shows me the RPS information, and failback happens when regular power is restored.
Is there something different about the 3560s, or did I miss something in the configuration? The switches are running 12.2(55)SE7, IP Services.
Go to Solution.
The switch not returning back to its own internal powersupply is normal. You have to use
power rps 1 port 1 mode standby
power rps 1 port 1 mode active
to have the switch switch back to its own powersupply. You could use the EEM to make it revert to the internal AC automatically.
I don't know about the missing information in show env rps.

Yes, just found via searching automatic failback is only supported on the 3560-E and 3750-E.
Also noticed the "power rps" commands are only supported on the 3560v2, so those won't work for me.
What's funny is while the exec commands don't work, the config-mode commands do.
Switch#power rps name serialnumber
Can not execute cmd on legacy switch 1
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#power rps deviceid serialnumber
Oh well. I've been wanting to replace the 3560s with 3750Gs, so this is yet another reason to do so!
