The Smart-UPS is a series of enterprise-level uninterruptible power supplies (UPS) manufactured by American Power Conversion (APC). Most units have SmartSlot (with the exception of SC and SMC series) that accept optional interface cards that provide features ranging from network connectivity to temperature and humidity monitoring. With the exception of the RT and SRT series, the Smart-UPS unit is a line-interactive UPS system, only running their inverters when grid power is not available.

There are several variations in the Smart-UPS list.

Management software
- All Smart-UPS units work with APC PowerChute software available for various operating systems.
- Free alternative to PowerChute is a free APC UPS Daemon (Apcupsd) software project, which supports Linux, Mac OS X, UNIX and Microsoft Windows operating systems and can run in standalone or client-server mode.
- Legacy Smart-UPS (Not SMX, SMT, or SURTD series) can also work with Network UPS Tools (NUT), third-party applications, under Linux. The software is designed to safely and automatically shut down all connected computers before the battery runs out.
Data interface
As a way to provide UPS management, automatic monitoring and termination 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 larger Smart-UPS models (and in many older cases) supporting two SmartSlots. The availability of SmartSlots in a Smart-UPS unit can be achieved through expansion modules such as AP9600 and AP9604 models. Installing an add-on card to SmartSlot will provide a UPS with additional features, which can go beyond the built-in serial data interface.
Early SmartSlot cards, such as AP9605, provide SNMP functionality and Telnet access. The AP9606 and later cards add a web interface that can be used to configure and manage UPS, as well as email based alerts. The AP9617 and newer cards add 10/100Base-T connectivity, Secure HTTP, Secure Shell (SSH), RADIUS, SNMP Version 3, PCNS and syslog functionality. AP9612, AP9618, AP9619 and AP9631 models provide environmental monitoring when used in conjunction with the APC temperature/humidity probe. The AP9618 model also provides out-of-band management via a modem connection if the 10/100 Ethernet connection is down.
SmartSlot cards remain powered by the battery even when the UPS is turned off, allowing the UPS to cool down even in a power loss situation (providing the network infrastructure is still powered and functioning). The card will also continue to work for a while after the UPS is turned off manually or due to low battery condition.
Starting with the 2009 release of the SMT model (and later the SMX and SURTD models), the old RS-232 data interface (serial port with DB-9 connector) has been replaced with 10-pin RJ50 sockets and RJ50-to-DB-9 attached wires to the protected computer serial port (along with the standard USB interface). In addition, the SmartSlot interface has been electrically modified in an incompatible and mechanically fit manner. As stated by APC, "new connection settings indicate a new signal system." The new serial interface and SmartSlot use a new signaling protocol Microlink that, unlike the previous APC protocol UPSLINK , since April 2015 is not publicly documented. However, using the new AP9620 interface card, users can add support for previous signaling protocols to the newer SMT and SMX models. The addition of this card makes the current model compatible with older software built for the older Smart-UPS series.
In August 2013 additional options are available in the form of new firmware for certain SMT and SURTD models, adding Modbus's publicly-documented signing capabilities to the proprietary Microlink protocol, enabling third-party developers to support UPS signaling and control on newer Smart Series- UPS.
SmartSlot card model
At the end of 2009, with the launch of SMT and SMX product lines, SmartSlot migrated to a new communications platform utilizing the APC Microlink protocol. Both the electrical and mechanical properties (slot keying) of the new SmartSlot make the older SmartSlot cards incompatible with the current Smart-UPS model. For example, the current Smart-UPS model (as of April 2015) SMT1500 is only compatible with AP9613, AP9620, AP9630 and SmartSlot AP9631 cards.
The new card/slot design is referred to as "Network Management CardÃ, 2" or NMC2. However, most of the new-style SmartSlot cards (including AP9613, AP9630, and AP9631) are backward compatible with older Smart-UPS models.
