—sbindir=<path> This defines the directory for the executable files such as apcupsd. The default is /sbin. You may be tempted to place the executable files in /usr/sbin or /usr/local/sbin. Please use caution here as these directories may be unmounted during a shutdown and thus may prevent the halt script from calling apcupsd to turn off the UPS power. Though your data will be protected, in this case, your system will probably not be automatically rebooted when the power returns.

—enable-powerfluteThis option enables the building of the powerflute executable, which is a ncurses based program to monitor the UPS. This program is not necessary for the proper execution of apcupsd.

—enable-cgiThis enables the building of the CGI programs that permit Web browser access to apcupsd data. This option is not necessary for the proper execution of apcupsd.

—with-cgi-bin=<path> The with-cgi-bin configuration option allows you to define the directory where the CGI programs will be installed. The default is /etc/apcupsd, which is probably not what you want.

—with-css-dir=<path> This option allows you to specify where you want apcupsd to put the Cascading Style Sheet that goes with the multimoncss.cgi CGI program.

—enable-master-slaveTurns on the master/slave networking code (de- fault). This is sometimes referred to as the old master/slave code, and is more complicated than using NIS and the net driver to control Slaves (see below).

—enable-apcsmartTurns on generation of the APC Smart driver (de- fault).

—enable-dumbTurns on generation of the dumb signalling driver code (default).

—enable-usbTurns on generation of the Linux (only) USB driver code. By default this is disabled.

—enable-netTurns on generation of the NIS network driver for slaves. This is an alternative to old master/slave code. For the master, this code should be disabled. For each slave, this is the only driver needed. This driver works by reading the information from the the configured master using the NIS (Network Information Services) interface.

—enable-snmpTurns on generation of the SNMP driver. This driver will control the computer by reading the UPS information over the network assuming you are running SNMP. By default this is disabled.

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.
