In the newsletter I received from MT today was a story that said the fan voltage can be read in SNMP. I did an SNMP walk to the 333 I have running, but did not see the voltage.
What is the OID of the fan voltage?
I also tried to read the voltage through snmp. I would be glad if someone had the answer…
with telnet it works on rb333:
system health print brings up the input voltage.
I found it this morning. The OID is:
1.3.6.1.4.1.14988.1.1.3.8.0
It displays as a 3 digit integer, so you have to divide by 10 to get the voltage.
I have a probe setup on it that watches for it to go < 25. For my configuration, that means battery power, so now I can be alerted when it goes to battery.
