I am using NUT 2.6.5 as part of FreeNAS 9.2.0. I am using an APC Smart-UPS 5000 RM DL4 with a AP9619 network management card. NUT properly detects when the UPS goes on battery and initiates a shutdown after the configured time. The problem I have is that I am using a 208V unit on a 240V circuit. That means the normal state for the UPS is "TRIM". NUT doesn't treat that as an on line condition, so the system shuts down every time there is a power failure. I realize what I am doing is a bit of a kludge, but I can't get a 208V circuit easily in my hous...

...cumented on http://homepage1.nifty.com/Que/plamo/apc-ups/manual/upsbible.html under "Old Firmware Revision". This implies that many more combinations of characters could be added to support more revisions & configurations. Indeed, 0XI and 0XM only differ by the placement of the 208V/240V input voltage select wire. The first character can be 0 or 5 for Matrix-UPS 3000 vs. Matrix-UPS 5000. The second character is the actual firmware revision. I've read in various forums about revisions U, W, X, Y, and Z. There is probably a V as well. The last character seems to be I...

Hi, I am trying to configure my Tripp Lite SU5000RT3U on Ubuntu 18.04 as I am not able to completely get all the data from the UPS. After installing all required packages from the Ubuntu repos (had to run sudo apt-get install dkms, I had to install the displaylink drivers from displaylink.org by doing sudo ./displaylink-driver-4.2.29.run, and I created a sim link by doing the following: sudo ln

I did reach out to their product support, and I did not have install the displaylink driver as that is for a totally different product, so ignore all that. > > The 208 V makes sense. The unit spec designates it as a 208V input, and from looking at what we have in the server room, the battery is a 48VDC power source.

...43 38 37 0d 00 00 '6C87...' https://github.com/networkupstools/nut/blob/v2.7.4/drivers/tripplite_usb.c#L1258-L1276 parses this into input.voltage and battery.voltage, but there is some weird scaling (or maybe even nonlinearity) going on with the input voltage. Does a nominal AC voltage of 208V or 240V sound right? The driver would probably calculate nominal battery voltage as 48V (using the "08" from ups.debug.V, times 6V). With the value above, you would have 0x87 * 48 / 12.0 = 54.0 Volts. > ups.debug.L: 31 31 35 41 30 31 0d '115A01.' Load might be 17% (0x11). I...

I have a simple perl script that every few hours pings the handful of machines on my LAN.

Hello. I am going to be putting together my first * system using FXO/FXS interfaces. All the systems I have set up thus far have been pure VoIP setups. The system I need to set up should have 3 FXO interfaces and 1 FXS interface, as well as several SIP phones. I have noticed people complaining about Digium's TDM cards - are these isolated incidents or are these cards unreliable? I intend to
