Have Cisco stack of 3750G -48 port(3) with stackwise cables; working ok. Have new Cisco RPS 2300. Cables connected to back of each 3750G in stack. On front of RPS panel, two LED's blinking green (ready to supply power if needed)but the other LED is solid amber which I read indicates that the RPS power is not available. Does anyone know why this would be the case? Nothing different was done to the 3rd switch in stack. Same cable used running to RPS. All three 3750G's where up when we attached to back of RPS with the three cables for the RPS. Cannot configure RPS via cammand line since these are NOT 3750E calss switches. Any ideas would help. Thanks.
