APC Symmetra LX Replacement

Modernize discontinued Symmetra LX systems with the Xtreme Power M90S modular platform

Organizations still running APC Symmetra LX UPS systems face growing lifecycle risk. The platform is discontinued, replacement modules and battery frames are increasingly hard to source, and long-term service support is declining.

The Xtreme Power M90S modular UPS is engineered as a direct modernization path for Symmetra LX installations from 4 kVA to 16 kVA. It preserves the modular architecture LX users rely on while eliminating legacy constraints — non-unity power factor, proprietary battery frames, and limited scalability — and scales from 6 kVA to 48 kVA within a single platform. Whether you’re replacing a Symmetra LX 4000, 8000, 12000, or 16000 tower or rack system, the M90S is a supported, serviceable, scalable successor.

Lifecycle Risk

Why Symmetra LX systems are being replaced

Symmetra LX systems were widely deployed in IT rooms and edge environments, but the platform is now end-of-life. Organizations maintaining legacy LX installations face:

  • Declining availability of power modules and battery frames
  • Aging VRLA battery architectures and rising maintenance cost
  • Limited usable power due to a < 1.0 power factor design
  • Capacity ceilings at 16 kVA per frame
  • Increasing service complexity from legacy modular electronics

Lifecycle status. The Symmetra LX platform has been discontinued and superseded by newer Schneider Electric architectures. Schneider’s own product documentation confirms the lifecycle status — see the Schneider Electric product page.

The Successor Platform

M90S — a modern Symmetra LX successor

The M90S modular UPS family is designed specifically for Symmetra LX migration — maintaining architectural continuity while delivering improved performance and scalability.

  • Unity power factor for higher usable capacity
  • Expansion to 48 kVA without a platform change
  • Hot-swappable power and battery modules
  • Integrated maintenance bypass
  • Rack or tower deployment flexibility
  • Supported, current-production modular platform

Hot-swappable modules and integrated maintenance bypass keep the M90S serviceable in production — capacity grows without a platform replacement
Capacity Mapping

Replace Symmetra LX 4000, 8000, 12000 & 16000

Many legacy deployments are referenced by capacity rather than APC part number. The M90S directly replaces the commonly searched Symmetra LX systems:

  • Symmetra LX 4000 replacement UPS
  • Symmetra LX 8000 replacement UPS
  • Symmetra LX 12000 replacement UPS
  • Symmetra LX 16000 replacement UPS

Modernize once, expand later. Unlike Symmetra LX, which was limited to 16 kVA per frame, the M90S scales to 48 kVA within a single UPS architecture — so you can grow capacity without replacing the system.

Rack-Mount

Symmetra LX RM (rack-mount) replacement

Discontinued Symmetra LX RM and RMP rack systems can be directly replaced with M90S rack-mount configurations using Xtreme Power rack kits.

Higher density

More power in standard IT racks.

Integrated bypass

Maintenance bypass within the UPS frame.

Clean migration

Straightforward electrical migration from LX RM installs.

Rack deployments use the Xtreme Power M90S rack-mount kit.
