Choose it when 1U height and an LCD matter, and your load stays within 400W. For a different power design, our hybrid UPS system guide explains the term, while the DC UPS system guide covers DC-powered backup.
How should you compare rack height, depth and power?
A rack UPS must fit the space and handle the connected load, so check all three before selecting a model. A 1U unit can save height, but it may have less capacity than a 2U model.
Measure the open rack space and compare it with the UPS dimensions or stated rack height. Also allow room for cables, airflow and access to outlets, and check whether the rack supports the unit's mounting method.
Next, total the wattage of the devices you plan to keep online. Choose a UPS with a watt rating above that sum, then decide whether planned expansion needs extra capacity.
Finally, map devices to battery-backed outlets. Some units have surge-only outlets as well, and those won't keep equipment running through an outage.
Which monitoring features are useful for a managed rack?
Choose monitoring based on how you want to check status and respond to power events. A front LCD helps with local checks, while software or remote services can help when the rack is unattended.
The SMART1500LCD's rotatable display shows runtime, load, battery and operating mode. The SMART500RT1U includes PowerAlert software and supports USB and RS232 monitoring connections.
The APC SmartConnect models add portal-based remote monitoring features, including automatic notifications and firmware updates. CyberPower's OR700LCDRM1U has an LCD, while remote management requires the optional RMCARD205 card.
Check whether the monitoring method works with your network and the equipment you already use. Remote visibility is useful only if you can receive and act on its alerts.
Does output type matter for rack equipment?
Output type can affect compatibility, so check the power requirements for your server, switch or storage device before buying. The APC SMT1500RM2UC and SMC1500-2UC specify pure sine wave output, while the OR700LCDRM1U specifies simulated sine wave.
The SMART1500LCD provides sine wave output in AC mode and modified sine wave output in battery mode. The SMART500RT1U's supplied product details don't state its output waveform, so verify compatibility if a connected device requires a specific type.
What should you check before installing a rack UPS?
Confirm rack fit, available power and outlet needs before mounting the UPS. Then follow the model's installation instructions and plan how you will monitor battery and load status.
Check the unit's height, depth and mounting hardware, along with room for power and network cables. The SMART500RT1U is 11.8 in deep as installed, and both APC 2U models include rack support rails.
A UPS protects only the devices connected to its backed-up outlets. Label those connections, keep surge-only devices separate and avoid exceeding the UPS's watt capacity.
Also decide how the rack will shut down during a long outage. Software connections and management features differ by model, so confirm the required cables, software and optional cards before installation.
Which rack mount smart UPS should you choose?
Choose the SMART500RT1U for a compact 1U rack and a load below 300W, or the CyberPower OR700LCDRM1U if you need 1U with a 400W ceiling and LCD. For 900W with a rotatable display, consider the SMART1500LCD.
Pick the APC SMT1500RM2UC if you need the highest stated watt capacity here, pure sine wave output and SmartConnect remote monitoring. The SMC1500-2UC offers a 900W APC alternative with similar monitoring features.
Before deciding, match your measured load to the UPS rating, confirm output compatibility and check that the rack has room for the unit and cables.
