Modernize Discontinued Symmetra LX UPS with Xtreme Power M90S Modular Platform
Organizations still operating APC Symmetra LX UPS systems are facing increasing lifecycle risk. The Symmetra LX platform is discontinued, replacement modules and battery frames are becoming difficult to source, and long-term service support is declining. As these systems age, IT and facilities teams are prioritizing Symmetra LX replacement strategies to maintain uptime and ensure serviceability.
The Symmetra LX platform is discontinued and replaced by newer Schneider Electric architectures, making migration to a supported modular UPS platform a priority for many organizations. Schneider Electric documentation confirms Symmetra LX lifecycle status:

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 Symmetra LX users rely on while eliminating legacy constraints such as non-unity power factor, proprietary battery frames, and limited scalability. M90S deployments scale from 6 kVA to 48 kVA within a single platform, enabling capacity growth without UPS replacement.
Whether replacing a Symmetra LX 4000, 8000, 12000, or 16000 tower or rack-mount system, the M90S provides a supported, serviceable, and scalable successor platform for single-phase critical power infrastructure.

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 APC power modules and battery frames
- Aging VRLA battery architectures and rising maintenance cost
- Limited usable power due to < 1.0 power factor design
- Capacity ceilings at 16 kVA per frame
- Increasing service complexity from legacy modular electronics
Modern modular UPS platforms such as the Xtreme Power M90S retain the hot-swappable architecture Symmetra LX users expect while providing higher usable power, broader scalability, and long-term platform support.
Symmetra LX vs Xtreme Power M90S Modular UPS
| Capability | APC Symmetra LX | Xtreme Power M90S |
| Platform status | Discontinued | Current production |
| Power factor | < 1.0 | Unity (kVA = kW) |
| Capacity range | 4–16 kVA | 6–48 kVA |
| Scalability | Limited to frame | Expandable platform |
| Battery architecture | Proprietary frames | Modular scalable |
| Maintenance bypass | External or frame-specific | Integrated |
| Serviceability | Aging modules | Current modular |
| Lifecycle outlook | Declining support | Long-term platform |
The M90S preserves the modular concepts that made Symmetra LX successful while modernizing performance and lifecycle support.
Xtreme Power M90S — Modern Symmetra LX Successor Platform
The M90S modular UPS family is designed specifically for Symmetra LX migration. It maintains architectural continuity while delivering improved electrical performance and scalability.
Key Symmetra LX migration advantages:
- Unity power factor for higher usable capacity
- Expansion to 48 kVA without platform change
- Hot-swappable power and battery modules
- Integrated maintenance bypass
- Rack or tower deployment flexibility
- Supported, current production modular platform

Replace APC Symmetra LX 4000, 8000, 12000 & 16000
Many legacy deployments are referenced by capacity rather than APC part number. The M90S directly replaces 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
Unlike Symmetra LX, which was limited to 16 kVA per frame, the M90S modular platform scales to 48 kVA within a single UPS architecture. This allows organizations to modernize once and expand capacity without replacing the system.
Symmetra LX RM (Rack-Mount) Replacement
Discontinued Symmetra LX RM and RMP rack systems can be directly replaced using M90S rack-mount configurations with Xtreme Power rack kits.
Rack-mount migration advantages:
- Higher power density in standard IT racks
- Integrated maintenance bypass within the UPS frame
- Clean electrical migration from Symmetra LX RM installations
- Continued modular serviceability
Rack deployments use the Xtreme Power M90S rack-mount kit.
Xtreme Power M90S Modular UPS Platform
The Xtreme Power M90S is a modular single-phase UPS family designed for continuous availability and simplified lifecycle service. The platform supports Symmetra LX replacement across IT rooms, edge sites, telecom facilities, and distributed infrastructure.
