RPS2300 Power revert back Behavior

Hi ,

   I proposed RPS2300 with dual PWR-7500.  I connected two WS-C2960S-48FPD-L to RPS2300.   when i disccounted AC power to both of 2960S switch and Let them use  Power from RPS.   after that, I discounted one of Power source from RPS2300. so Only one 2960S worked but when i put Power Source back to RPS2300.     the 2960S  that was working has been rebooted.    Is it normal behavior for RPS2300 ?

thanks

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.
