the Data (see DATA Logging) section of this manual for additional details.

FACILITY<log-facility> The facility directive can be used to change the system logging class or facility. The default is DAEMON. This parameter can be useful if you wish to direct the apcupsd system logging information to other than your system default files. See the Logging section of this manual for additional details.

Configuration Directives for Sharing a UPS

The following directives apply to the master/slave networking mode of apcupsd where multiple machines can be powered by the same UPS. One machine, the master, will have a serial port connection to the UPS, and the other machines, the slaves, will obtain their information via the network from the master.

Note, as of version 3.10.x, the old master/slave code is by default turned off in the configuration. You must explicitly enable it by including a --enable-master-slave option on your ./configure command before building the source.

In addition to the old master/slave code, there is now a new network driver enabled with --enable-net (default disabled) that can be used to control a slave from any version of apcupsd running NIS. This is a much more flexible system of controlling slaves because a slave machine that also has NIS turned on can thus act as a master for another slave with --enable-net turned on. With this mode turned on, the slave obtains the address of the master from the DEVICE directive, which takes the form hostname[:port] as a consequence, none of the directives apply for this form of networking. In addition, for this mode to work, you must specify UPSTYPE net so that the proper driver is loaded.

The remainder of this section presents directives that apply to the old mas- ter/slave code that must be enabled by the enable-master-slaveconfigu- ration option.

UPSCLASS <class of operation> [ standalone — shareslave — share- master ] and [ netslave — netmaster ] are valid types. [ standalone — netslave — netmaster ] are tested classes. [ shareslave — sharemaster ] classes are being tested.

The default is standalone and should be used for all machines pow- ered by the UPS and having a serial port connection to the UPS, but

UPS control system specifications

APC UPS (Uninterruptible Power Supply) control systems are vital components for ensuring uninterrupted power supply and protecting critical equipment from power interruptions, surges, or fluctuations. Designed by Schneider Electric, APC UPS systems are renowned for their high quality and reliability. They utilize advanced technologies and features to suit diverse applications, from home offices to large industrial settings.

One of the main features of APC UPS systems is the ability to provide backup power during outages. This is achieved through a battery system that activates immediately when the mains power fails. This seamless transition minimizes downtime and ensures that electronic devices continue to operate, protecting data integrity and equipment lifespan.

Another significant characteristic of APC UPS systems is their intelligent management capabilities. Most models come with PowerChute software, which provides users with real-time monitoring of power conditions and the status of the UPS. This software allows for graceful shutdowns of connected devices during extended outages, thereby preventing data loss and damage to devices.

APC UPS systems also incorporate advanced technologies such as Automatic Voltage Regulation (AVR). AVR technology ensures that the output voltage remains stable by correcting minor fluctuations without switching to battery mode. This not only prolongs the battery life but also provides a consistent power supply to the connected equipment.

Thermal management is another critical aspect of APC UPS control systems. The design often includes efficient cooling systems that prevent overheating, ensuring optimal performance and longevity of the unit. Some models feature EcoMode, which reduces energy consumption and lowers operational costs by working at high efficiency only when battery backup is not required.

APC UPS systems are designed with scalability in mind. Users can easily add more batteries or connect additional UPS units to accommodate growing power needs. Features such as hot-swappable batteries and modular design facilitate easy upgrades and servicing without interrupting power supply.

In terms of connectivity, APC UPS products often feature multiple options including USB, RS-232, and network management capabilities. This enables users to connect remote management tools and integrate the UPS with existing IT infrastructure.

In summary, APC UPS control systems deliver reliability, efficiency, and advanced technology features that cater to a wide array of power protection needs, making them a trusted choice for individuals and businesses alike.
