FreeBSD-4.11

NetBSD-2.0

NetBSD-1.6.2

OpenBSD-3.6

FreeBSD-5.3 has had the most testing since it is the primary platform on which the driver is developed. The other platforms and versions have had somewhat less testing. The only architecture tested so far (on any platform) is i386, althought there is no reason to think it will not work on other archs. If you run the driver on a new platform version or architecture, please report your experience to the apcupsd-users mailing list.

KERNEL CONFIGURATION

You will need to rebuild your kernel in order to disable the uhid driver. uhid is not sufficient for apcupsd at this time and we need to prevent it from grabbing the UPS device. You should disable the following devices in your kernel config file (comment them out):

FreeBSD (you WILL NOT lose use of USB keyboard and mouse): uhid

NetBSD (you WILL lose use of USB keyboard and mouse): uhidev, ums, wsmouse, ukbd, wskbd, uhid

OpenBSD (you WILL lose use of USB keyboard and mouse): uhidev, ums, wsmouse, ukbd, wskbd, uhid

CHECKING UPS IS RECOGNIZED BY THE KERNEL

After building a properly configured kernel, reboot into that kernel and plug in your UPS USB cable. You should see a dmesg log message like the following:

ugen0: American Power Conversion Back-UPS RS 1500 FW:8.g6 .D USB FW:g6, rev 1.10/1.06, addr 2

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.
