Apcupsd, short for APC UPS daemon, is a utility that runs on Linux, UNIX, macOS and Windows. [1]: 1, 8–9 It allows the computer to interact with APC UPSes. Apcupsd also works with some OEM-branded products (e.g. Hewlett-Packard) manufactured by APC. [1]: 7 [2] [3] Apcupsd is a free software equivalent of the APC's proprietary PowerChute software.
Network UPS Tools (NUT) is a suite of software component designed to monitor power devices, such as uninterruptible power supplies, power distribution units, solar controllers and servers power supply units. Many brands and models are supported and exposed via a network protocol and standardized interface.
The Smart-UPS is a series of enterprise-level uninterruptible power supplies (UPS) made by American Power Conversion (APC). [1] Most of the units have a SmartSlot (with the exception of SC and SMC series) which accepts an optional interface card providing features ranging from network connectivity to temperature and humidity monitoring.

It provides UPS management and safe server shutdown for up to 25 servers. [7] UPS Network Management Cards made by APC enable UPS management by directly connecting the UPS to the network with its own IP address, avoiding dependence or the need for a server, which can be useful in wiring closets where no servers are present.
A hybrid (double conversion on demand) UPS operates as an off-line/standby UPS when power conditions are within a certain preset window. This allows the UPS to achieve very high efficiency ratings. When the power conditions fluctuate outside of the predefined windows, the UPS switches to online/double-conversion operation. [8]
IPS/UPS has an interlink to the Nordic system via a back-to-back high-voltage direct current (HVDC) connection to Finland with a capacity of 1420 megawatts. [12] [obsolete source] In 2005, Russia and the EU considered unifying the IPS/UPS network with the ENTSO-E to form a single synchronous super grid spanning 13 time zones. [2]
A Web service is a method of communication between two electronic devices over a network. It is a software function provided at a network address over the Web with the service always-on as in the concept of utility computing. Many organizations use multiple software systems for management.
Network security elements are also usually deployed: firewalls, VPN gateways, intrusion detection systems, and so on. Also common are monitoring systems for the network and some of the applications. Additional off-site monitoring systems are also typical, in case of a failure of communications inside the data center.
