Network UPS Tools
Power Devices support

This project is the result of years of work by many individuals and companies.

Many people have written or tweaked the software; the drivers, clients, server and documentation have all received valuable attention from numerous sources.

Many of them are listed within the source code, AUTHORS file, release notes, and mailing list archives, but some prefer to be anonymous. This software would not be possible without their help.

Our main supporter: Eaton

Through the acquisition of MGE Office Protection Systems (a carve out of the MGE UPS SYSTEMS small systems, up to 10 KVA), Eaton has been supporting NUT, and more generally the Free/Libre Opensource Software Community since around 2002.

This support includes the following actions:

  • providing extensive technical documents (Eaton protocols library),

  • providing units to developers of NUT and related projects,

  • hosting the networkupstools.org webserver,

  • providing artwork,

  • promoting NUT in general.

For more detailed information on Eaton’s Opensource commitment, please refer to Eaton Opensource website.

Supporting manufacturers

UPS manufacturers

  • Eaton, our main supporter, as presented in the above section.

  • Gamatronic, through Nadav Moskovitch, has revived the sec driver (as gamatronic), and expanded a bit genericups for its UPSs with alarm interface.

  • Microdowell, through Elio Corbolante, has created the microdowell driver to support the Enterprise Nxx/Bxx serial devices. They also proposes NUT as an alternative to its software for Linux / Unix.

  • Powercom, through Alexey Morozov, has provided extensive information on its USB/HID devices, along with development units.

Appliances manufacturers

  • OpenGear has worked with NUT’s leader to successfully develop and integrate PDU support. Opengear, through Scott Burns, and Robert Waldie, has submitted several patches.

Other contributors

  • Pavel Korensky’s original apcd provided the inspiration for pursuing APC’s smart protocol in 1996

  • Eric Lawson provided scans of the OneAC protocol

  • John Marley used OCR software to transform the SEC protocol scans into a HTML document

  • Chris McKinnon scanned and converted the Fortress protocol documentation

  • Tank provided documentation on the Belkin/Delta protocol

  • Potrans provided a Fenton PowerPal 600 (P series) for development of the safenet driver.

Older entries (before 2005)

  • MGE UPS SYSTEMS was the previous NUT sponsor. They provided protocols information, many units for development of NUT-related projects. Several drivers such as mge-utalk, mge-shut, snmp-ups, hidups, and usbhid-ups are the result of this collaboration, in addition to the WMNut, MGE HID Parser the libhid projects, … through Arnaud. All the MGE supporters have now gone with Eaton (through MGE Office Protection Systems), which is the new NUT sponsor.

  • Fenton Technologies contributed a PowerPal 660 to the project. Their open stance and quick responses to technical inquiries were appreciated for making the development of the fentonups driver possible. Fenton has since been acquired by Metapo.

  • Bo Kersey of VirCIO provided a Best Power Fortress 750 to facilitate the bestups driver.

  • Invensys Energy Systems provided the SOLA/Best "Phoenixtec" protocol document. SOLA has since been acquired by Eaton.

  • PowerKinetics technical support provided documentation on their MiniCOL protocol, which is archived in the NUT protocol library. PowerKinetics was acquired by the JST Group in June 2003.

  • Cyber Power Systems contributed a 700AVR model for testing and development of the cyberpower driver.

  • Liebert Corporation supplied serial test boxes and a UPStation GXT2 with the Web/SNMP card for development of the liebert driver and expansion of the existing snmp-ups driver. Liebert has since been acquired by Emerson.

Note If a company or individual isn’t listed here, then we probably don’t have enough information about the situation. Developers are requested to report vendor contributions to the NUT team so this list may reflect their help. If we have left you out, send us some mail.
