Why Cisco 6509-E indicates "operationally non-redundant"? and occasionally, one of slot is reloaded itself. It might be couple of reasons, but in my workaround it was low power-input on one of power supply. Due to the circumstance, other power supply will be overwhelming to provide all the powers.
Here is output
1. Type show power to identify "operationally = non-redundant"
Cisco_6500-E# show power system power redundancy mode = redundant system power redundancy operationally = non-redundant system power total = 2573.32 Watts (62.56 Amps @ 42V) system power used = 1374.52 Watts (31.06 Amps @ 42V) system power available = 1245.80 Watts (30.40 Amps @ 42V) Power-Capacity PS-Fan Output Oper PS Type Watts A @42V Status Status State ---- ------------------ ------- ------ ------ ------ ----- 1 WS-CAC-2700W 2573.32 62.56 OK OK on 2 WS-CAC-2700W 1374.52 31.06 OK OK on

3. As you can see power supply 2 is getting low AC power-input. If power input is not matched, it will be caused "operationally = non-redundant".
4. Check power-input on power-supply 2
