We have multiple TrippLite Omni900LCD UPS. There are a couple pieces of
equipment connected to each UPS. I would like to connect the UPSs to one
computer through USB which would shutdown the appropriate equipment based on
events monitored by upsmon using upssched. I've configured NUT using
usbhid-ups driver and compiled/installed NUT. I've done some testing and it
seems to work. Unfortunately all the USB ports are on the same bus for the
computers that I could use for this and the TrippLites seem to use the same
serial number. Any way to uniquely identify the UPSs to NUT? Or maybe to
set a value in the UPS that could be used to identify the UPS?
Thanks.

This command will dump all the variables that the UPS has and we *might* be able to tell them apart. The first few seconds of output should be enough.

No they bear absolutely no resemblance to the real serial numbers. Could be some internal model number used by TrippLite. Either way not useful for identifying a distinct UPS. ----- Original Message ----- From: "Charles Lepple" <clepple at gmail.com> To: "Todd Woods" <twoods at commo.com> Cc: "Arjen de Korte" <nut+users at de-korte.org>; "nut" <nut-upsuser at lists.alioth.debian.org> Sent: Friday, August 31, 2007 3:14 PM Subject: Re: [Nut-upsuser] Multiple Tripplite OMNI900LCD> On 8/31/07, Todd Woods <twoods at commo.com> wrote: >> ------------------------------------ >> One UPS plugged into first USB port >> ------------------------------------- > [...] >> - Serial Number: FW-2263 E > [...] >> --------------------------------------------- >> Different UPS plugged into second USB port >> ---------------------------------------------- > [...] >> - Serial Number: FW-2263 E > > odd... do either of these serial numbers look similar to any serial > numbers on the product label? > > -- > - Charles Lepple >
