C3750X - Power supply OIDs problems

Question

Hello,
We are trying to monitor two stacks of CISCO WS-c3750X running IOS 12.2.(58)SE.
We can get the state of the power supplies, but after a power cycle or reboot of the switches the identifier of ONE of the Power supplies ALWAYS change. The OIDs for the rest of the PS do not vary. The problem happens in the two stacks.
Any idea or work around?
Kind regards

Hi,
I'm trying to determine if the issue addressed in this post is a match with the following symptom:
As you can see from the output below - the switch 2 power supplies appear to be healthy:
SWITCH#show env power switch 1
SW  PID                 Serial#     Status           Sys Pwr  PoE Pwr  Watts
1A  C3KX-PWR-350WAC     AZS161707F3  OK              Good     Good     350/0
1B  C3KX-PWR-715WAC     LIT16180RRU  OK              Good     Good     715/0
SWITCH#show env power switch 2
SW  PID                 Serial#     Status           Sys Pwr  PoE Pwr  Watts
2A  C3KX-PWR-715WAC     LIT16180RRY  OK              Good     Good     715/0
2B  C3KX-PWR-350WAC     AZS161707FZ  OK              Good     Good     350/0
Yet, the snmpwalk output shows a Sw2 PS2 power supply fault:
              snmpwalk -v1 X.X.X.X  -c READONLY .1.3.6.1.4.1.9.9.13.1.5.1
SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.1035 = STRING: "Sw1, PS1 Normal, RPS NotExist"
SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.1036 = STRING: "Sw1, PS2 Normal, RPS NotExist"
SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.2034 = STRING: "Sw2, PS1 Normal, RPS NotExist"
SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.2035 = STRING: "Sw2, PS2 Faulty, RPS NotExist"
Do my symptoms match with the issue addressed in this post ?
TIA,
Amir
