SNMP - getting temperatures og blade switches M6348 Force10 MXL

Hi 

We are trying to monitor blade switches temperature, but cant find correct IODs for temperature on 

* PC  M6348

* Force10 MXL

Does theyr SNMP trees contain values that cam be shown by :

show environment (F10 switches) and show system temperature (PC switches)

What are the correct OIDs
