This page contains information about installing the latest APC UPS driver downloads using the APC Driver Update Tool.

APC UPS drivers are tiny programs that enable your UPS hardware to communicate with your operating system software. Maintaining updated APC UPS software prevents crashes and maximizes hardware and system performance. Using outdated or corrupt APC UPS drivers can cause system errors, crashes, and cause your computer or hardware to fail. Furthermore, installing the wrong APC drivers can make these problems even worse.

Recommendation: If you are inexperienced with updating APC device drivers manually, we highly recommend downloading the APC UPS Driver Utility. This tool will download and update the correct APC UPS driver versions automatically, protecting you against installing the wrong UPS drivers.

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.^[2] With the exception of RT and SRT series, Smart-UPS units are line-interactive UPS systems, only running their inverters when the grid power is unavailable.

Models[edit]

There are a few different variations in the Smart-UPS lineup.

Model	Characteristics
Smart-UPS	The standard model, with true sine-wave inverter output. Later known as the Smart-UPS SMT.
Smart-UPS SC	A simplified version of the Smart-UPS, based on Back-UPS architecture with no SmartSlot expansion and with modified sine wave output. It is incompatible with many active PFC PC power supplies.^[3]
Smart-UPS SMC	An economy version of the Smart-UPS SMT, with no SmartSlot expansion and with a simplified LCD display. It outputs a pure sinewave.
Smart-UPS XL	An 'extended run' series, with an Anderson Powerpole DC connector allowing up to 10 external battery packs to be daisy-chained to the main unit.
Smart-UPS RT, Smart-UPS SRT	An online/double-conversion variant providing no switchover delay during a power loss.
Smart-UPS VT	Uses three-phase power, for larger installations.

Management software[edit]

All Smart-UPS units work with APC's proprietary PowerChute software which is available for a variety of operating systems.
A free alternative to PowerChute is the Free software project APC UPS Daemon (Apcupsd), which supports Linux, Mac OS X, UNIX and Microsoft Windows operating systems and can run in stand alone or client-server modes.
Legacy Smart-UPS (Not SMX, SMT, or SURTD series ^[4]) can also work with Network UPS Tools (NUT), a third party application, under Linux.^[5] The software is designed to safely and automatically shut down any connected computers before the batteries are depleted.

Data interfaces[edit]

As a way to provide UPS management, monitoring and automatic shutdown of attached equipment, all Smart-UPS models include at least one serial data interface (RS-232 or USB), while most models also have at least one SmartSlot expansion port, with the larger (and in many cases older) Smart-UPS models supporting two SmartSlots. Availability of more SmartSlots in a single Smart-UPS unit can be achieved via expansion modules such as the AP9600 and AP9604 models.^[6]^[7] Installing an add-on card into a SmartSlot will provide the UPS with additional features, capable beyond the default serial data interface.

Early SmartSlot cards, such as the AP9605, provide SNMP functionality and Telnet access.^[8] The AP9606 and later cards add a web interface that can be used to configure and administer the UPS, as well as email-based alerting. The AP9617 and newer cards add 10/100Base-T connectivity, Secure HTTP, Secure Shell (SSH), RADIUS, SNMP Version 3, PCNS and syslog functionalities.^[9] The AP9612, AP9618, AP9619 and AP9631 models provide environmental monitoring when used together with APC temperature/humidity probes.^[10]^[11]^[12] The AP9618 model also provides out-of-band management via a modem connection in case the 10/100 Ethernet connection is down.

SmartSlot cards remain powered by the battery even when the UPS is switched off, allowing the UPS to be remotely cold-started even in a power loss situation (presuming the network infrastructure is still powered up and functioning). The cards will also continue to work for a short while after the UPS has been switched off either manually or due to a low battery condition.^{[citation needed]}

Beginning with the 2009 release of the SMT models (and later SMX and SURTD models), the old RS-232 data interface (a serial port with DB-9 connector) has been replaced with a 10-pin RJ50 socket and an RJ50-to-DB-9 cable connecting to the protected computer's serial port (together with a standard USB interface^[13]). Also, SmartSlot interface has been electrically modified in a backward-incompatible way and appropriately keyed mechanically. As stated by APC, 'the new connection arrangement denotes the new signalling systems.'^{[citation needed]} These new serial and SmartSlot interfaces use the new Microlink signalling protocol which, unlike the previous APC protocol UPSLINK, as of April 2015 has not been publicly documented. However, using the new AP9620 interface card, users are able to add support for the previous signalling protocol to the newer SMT and SMX models. Addition of this card makes the current models backwards compatible with older software built for the older Smart-UPS series.

As of August 2013, an additional option has been made available in form of new firmware for certain SMT and SURTD models, adding publicly documented Modbus signalling capability to the proprietary Microlink protocol, allowing third-party developers to support UPS signalling and control on the newer Smart-UPS series.^[14]^[15]
