High-Availability Power Protection with Symmetra LX
High-Availability Power Protection with Symmetra LX
The Symmetra LX is a high-performance, double-conversion on-line uninterruptible power supply (UPS) engineered to provide highly available, redundant, and scalable power protection for your critical IT infrastructure. Recognizing that modern IT demands agility, the Symmetra LX is the first UPS to offer both redundancy and scalability within a single, space-saving chassis. Designed to safeguard hardware, software, and data, it ensures continuous power delivery from its internal batteries until utility lines are restored to a safe level.
Whether you are outfitting a server room, a data center, or a distributed network environment, the Symmetra LX series delivers a robust architecture that grows seamlessly with your business, ensuring you never pay for more capacity than you currently need.
Solving Modern Power Challenges
The Problem
Modern IT environments face a dual challenge: the critical need for uninterrupted uptime and the unpredictability of future power demands. Power disturbances such as blackouts, brownouts, surges, and sags can instantly cripple operations, damage expensive electronic equipment, and corrupt valuable data. Furthermore, traditional UPS systems force businesses to estimate their future power needs up front, often leading to costly over-provisioning or the need for a complete “rip-and-replace” upgrade when capacity is exceeded. Maintaining traditional UPS systems also typically requires bringing down mission-critical loads, resulting in planned downtime.
The Solution
The Symmetra LX eliminates these pain points through its modular, redundant architecture. By allowing you to scale both power capacity and runtime as your demand increases, it completely removes the guesswork from capacity planning. If higher levels of availability are required, the system can be configured for N+1 internal redundancy. To solve the issue of maintenance downtime, the Symmetra LX features hot-swappable modules, ensuring you never have to bring down your mission-critical loads to service the unit or add capacity.
Key Features
Why Choose Symmetra LX
The double-conversion on-line design ensures a pure sine wave output with zero transfer time, completely isolating your critical load from utility power anomalies.
Lower Total Cost of Ownership (TCO)“Pay as you grow” scalability allows you to invest only in the power and runtime modules you need today, seamlessly expanding your infrastructure as your business scales. High efficiency (up to 90% at full load) minimizes energy consumption and cooling costs.
Because all primary components are hot-swappable—and because the system features automatic and manual internal bypass capabilities—routine maintenance and capacity upgrades can be performed while the UPS continues to protect the load.
Seamless IT IntegrationRack-mount models ship with standard receptacles, while the system’s removable input/output wiring trays and robust communication interfaces guarantee smooth integration into any server room or data center.
Real-World Deployments
K-12 Education and Distributed IT Environments
As educational institutions heavily integrate technology—such as 1:1 computing initiatives and online standardized testing—reliable IT infrastructure is no longer a luxury, but a necessity. Devices like routers that provide critical internet connections draw relatively little power but must remain online during utility disruptions; the Symmetra LX can power this essential network gear for hours. When deployed in a secure enclosure (like a NetShelter rack), the Symmetra LX provides the essential power protection needed to keep 21st-century classrooms online. Furthermore, organizations can often leverage funding programs, such as the federal E-rate program, which offers substantial rebates for deploying essential power protection, racks, and enclosures.

How to Choose the Right Model for Your Needs
If you are a buyer evaluating these systems, understanding the naming conventions and features will help ensure this product perfectly aligns with your infrastructure:
Models ending in “P” or “RMP” are optimized for North American 208V/240V nominal inputs and outputs. Models ending in “I” or “RMI” are built for International deployment, supporting 220/230/240V (single phase) or 380/400/415V (3-phase) nominal inputs and 230V outputs.
Select Your Form Factor (Tower vs. Rack-Mount)Rack-mount variants (denoted by “RM”) are designed to seamlessly integrate into standard IT enclosures, taking up 13U for up to 8 kVA chassis and 19U for 16 kVA chassis. Tower options stand independently and are ideal for areas lacking dedicated rack space, like distributed network closets.
Symmetra LX’s modularity means you can configure the system for N+1 internal redundancy. For example, the SYA8K16RMP ships with 8 kVA of power out of the box, but resides in a 16 kVA-capable frame. This allows you to hot-swap additional power modules into the chassis as your load increases, completely eliminating the need for costly “rip-and-replace” upgrades.
Hot-Swappable MaintenanceAll modules—including batteries, power modules, and intelligence modules—can be replaced without powering down the connected IT load, which effectively translates to zero planned downtime.
