[problemsnetwork-services]

Hi,

I am attempting to configure a 3750-E Cat with and RPS2300. However, regardless of what power/rps command i enter i always received the following error :-

Can not execute cmd on legacy switch 1

Has any one experianced the same issue or know he fix.

1.The Catalyst 3750 and 3560 switches do not support the power supply command.

2.The Catalyst 3750 and 3560 switches do not support the power rps user EXEC command. You cannot configure the redundant power system (RPS) name, RPS port name, or RPS port priority on these switches.
