I was wondering if there was any support in NUT for networked APC
UPS's. All the configuration examples I see in the documentation are
for USB/Serial connections to the UPS. I could mess around with
serial/USB cables, but I'd really rather talk to the UPS over the
network. I don't want all my servers relying on a single machine with
a serial connection.
Does your APC UPS support SNMP? There is a 'snmp-ups' driver that
understands several manufacturers' MIB formats, including APC's, I
believe.
Cool, I'll give that a try when my new UPS comes in.
You still may end up with a single point of failure, though, since you
probably only want one machine commanding the UPS to power down. (A
data center could avoid this with dual-input power supplies fed from
separate UPSes.) Someone else who is more familiar with snmp-ups may
have more insight into this.
Eh? Why would I want to command the *UPS* to power down? The UPS will
power down if and when the battery goes dead.
Or did I misunderstand that? I want all my servers to power down
using the UPS itself as the "master" instead of picking a server as a
master.
