The MCE has temperature sensors on each FPGA, on each card, and on the rack (box). These can be quickly read from the mce by running mce_status and grepping for 'temp':
mce_status -s | grep temp
The output will look something like (these are from ACT S204):
cc fpga_temp : 78 cc card_temp : 28 cc box_temp : 50 rc1 fpga_temp : 38 rc1 card_temp : 32 rc2 fpga_temp : 39 rc2 card_temp : 32 rc3 fpga_temp : 39 rc3 card_temp : 32 rc4 fpga_temp : 38 rc4 card_temp : 32 bc1 fpga_temp : 27 bc1 card_temp : 26 bc2 fpga_temp : 26 bc2 card_temp : 24 bc3 fpga_temp : 28 bc3 card_temp : 26 ac fpga_temp : 14 ac card_temp : 26
The numbers listed have units of Celsius, with the following exceptions (as of July 1, 2008):
- "cc fpga_temp" and "cc box_temp" in Rev. B Clock Cards only, are scaled by a factor of 2. A reading of 78 indicates a temperature of 39 celsius.
- "ac fpga_temp" in pre-Rev D Address-cards is scaled by a factor of 1/2. A reading of 14 indicates a temperature of 28 celsius.
