Hi John,

For monitoring status of power supplies and fan we use SNMP. I've included an example for OIDs and values fo a C5:

Number and instances of power supplies
SNMPv2-SMI::enterprises.52.4.3.1.2.1.1.1.101 = INTEGER: 101
SNMPv2-SMI::enterprises.52.4.3.1.2.1.1.1.102 = INTEGER: 102

State of power supplies
[infoNotAvailable(1), notInstalled(2), installedAndOperating(3), installedAndNotOperating(4)]
SNMPv2-SMI::enterprises.52.4.3.1.2.1.1.2.101 = INTEGER: 3
SNMPv2-SMI::enterprises.52.4.3.1.2.1.1.2.102 = INTEGER: 2

Redundancy status of power supplies
[redundant(1), notRedundant(2), notSupported(3)]
SNMPv2-SMI::enterprises.52.4.3.1.2.1.1.4.101 = INTEGER: 1
SNMPv2-SMI::enterprises.52.4.3.1.2.1.1.4.102 = INTEGER: 1
--> The information provided by these OID must be interpreted in dependancy on "State of power supplies" and are valid only if more than one power supply is installed (built in and external power supply).

Number of fan modules
SNMPv2-SMI::enterprises.52.4.3.1.3.1.1.1.101 = INTEGER: 101
SNMPv2-SMI::enterprises.52.4.3.1.3.1.1.1.102 = INTEGER: 102
SNMPv2-SMI::enterprises.52.4.3.1.3.1.1.1.103 = INTEGER: 103
SNMPv2-SMI::enterprises.52.4.3.1.3.1.1.1.104 = INTEGER: 104

State of fan modules
[infoNotAvailable(1), notInstalled(2), installedAndOperating(3), installedAndNotOperating(4)]
SNMPv2-SMI::enterprises.52.4.3.1.3.1.1.2.101 = INTEGER: 3
SNMPv2-SMI::enterprises.52.4.3.1.3.1.1.2.102 = INTEGER: 2
SNMPv2-SMI::enterprises.52.4.3.1.3.1.1.2.103 = INTEGER: 3
SNMPv2-SMI::enterprises.52.4.3.1.3.1.1.2.104 = INTEGER: 2

In case of fan failures syslog messages are been generated.

I hope this helps

Hello:

We have recently converted to Enterasys from Cisco.  I am getting my
monitoring and alerting setup and would like to know what you find useful to
alert on as well as how to do it.

Currently I am looking for a way to know if a power supply fails.  If a
switch has an RPS and the primary PS goes down I'd like to know about it.
Is there a way to make that happen?  So far my C5 is not sending a trap or a
syslog message when I unplug the primary PS.

Thanks
