M4300 8X8F and 24X24F - Wrong temperature
The web UI and SNMP polling show temperature on 8X8F and 24X24F devices as being very different to 28G which is mounted directly above it.
We have 4 stacks of Netgear M4300 equipment, in separate DCs which all exhibit this problem.
What information should I provide?

All these units are racked correctly, ports facing cold isle and fans towards the hot isle.

A third stack, again in a different DC. This doesn't have 28G stack members but other equipment in the stack reports its system temperature about 30 degrees lower and MAC temperature about 20 degress lower.
