Goal	How do I check the temperature and voltage on the Celerra? How to run the t2adc command to check the temperature and voltage on the Celerra.

Issue	"BoxMonitor:2:10 Slot 6, Over temperature warning" found in the sys_log Slot x, xV DC supply low / high in the sys_log. Error msg: 12v DC Supply Low Error msg: Segmentation fault (core dumped) when t2adc is run. BoxMonitor:2:19 Slot 3, -12V DC Supply low

Environment	All NAS Codes Product: Celerra Network Server (CNS-14) Product: Celerra File Server (CFS-14)

Cause	Temperature has exceeded threshold on the Data Movers or Control Station. Voltage has exceeded threshold on the Data Movers or Control Station.

Resolution	Check /nas/log/sys_log and /nas/log/osmlog and the particular server_log for any reference to hardware indications or sibpost errors. The sibpost error code for -12 VDC powr supply is 0x00000047. Also run the /nas/sbin/t2adc command to see a list of the voltages for the specified Data Mover. You can execute the /nas/sbin/t2adc command without shutting down the BoxMonitor application in certain code revisons. If you cannot execute the t2adc command, then get confirmation or permission prior to shutting down BoxMonitor. Example: [nasadmin@cel4cs0 nasadmin]$ server_version server_2;/nas/sbin/t2adc server_2 :Product: EMC Celerra File Server Version: T5.1.20.401 Box 5V 12V 3.3V -5V -12V 5V Trim 12V Trim Temp 0 5.02 11.98 0.00 -0.01 -11.95 4.50 10.80 30.91 2 5.06 11.94 3.35 -0.01 - 0.02 4.50 10.80 35.08 3 5.07 12.00 3.34 -0.01 - 0.01 4.50 10.80 35.20 4 5.00 12.18 0.00 -0.00 -11.91 4.50 10.80 29.20 5 5.02 12.00 0.00 -0.00 -11.85 4.50 10.80 28.15 If you have to halt Boxmonitor, as root run /etc/rc.d/rc3.d/S95nas stop Then run the t2adc command.
