hplog question

[Dan Draghici]

Hello,
I have a little question regarding the hplog utility:
I intend to use it on a bunch of ML 370 servers.
When I issue an "hplog -t" it returns:
ID TYPE LOCATION STATUS CURRENT THRESHOLD
1 ADM1022 Processor Zone Nominal 104F/ 40C 134F/ 57C
2 ADM1022 CPU (1) Nominal 120F/ 49C 176F/ 80C
3 ADM1022 I/O Zone Nominal 102F/ 39C 127F/ 53C
4 ADM1022 CPU (2) Absent ---F/---C ---F/---C

Now I understand the part about the CPU temp, but could anyone please tell me what exactly does the "I/O Zone" & "Processor Zone" refer to?!
Thanks,

Processor Zone - The area sourounding the processor on System Board.

I/O Zone - area sourounding the I/O expansion slots.

CPU - processor socket (on some processor, the temperature sensor is inbuilt)
