Hi sompoj,
have you or anyone of you found a solution for this behavior.
I got the same problem at a customers site.
There are two WS-C2960S-24TS-L connected to a PWR-RPS2300.
During our failover tests we noticed that our WS-C2960S-24TS-L wont switch back to internal power supply automatically.
For some reason the Switch stay in BackingUp mode at the PWR-RPS2300.
At my research for this behavior I found this Cisco document where it says that the WS-C2960S should be able to switch back automatically.
Now I like to ask if there is a known issue or anything have to be configured.
I added output from my tests.
