APC Symmetra LX 8kVA N+1 Tower UPS – 208/240V

Experience mission-critical power protection tailored for modern data centers, server rooms, and network closets. The APC Symmetra LX 8kVA N+1 Tower, designed for space-constrained environments, blends scalable runtime, modular redundancy, and a compact footprint to safeguard servers, storage, and networking gear. With transformer-based online double-conversion technology, it delivers clean, conditioned power and precise regulation, even in the face of fluctuating utility inputs. Whether you’re architecting a small data center, upgrading an edge site, or engineering a resilient network backbone, Symmetra LX offers the flexibility to grow as your infrastructure expands, while maintaining uptime and protecting critical workloads.

• Modular, hot-swappable design for ongoing uptime — The Symmetra LX is built with hot-swappable power modules and battery modules that can be replaced without shutting down connected equipment. This modular approach enables continuous operation during maintenance, minimizes planned downtime, and simplifies expansion as your load increases. The system’s architecture is engineered to keep critical servers and network devices running while technicians service individual modules, delivering true redundancy without compromise.
• N+1 redundancy for uncompromising availability — Engineered for environments where uptime is non-negotiable, the Symmetra LX supports N+1 redundancy, ensuring that a single module failure or maintenance cycle does not disrupt power to protected loads. This design is ideal for space-limited data closets and branch data centers, where downtime can cascade into lost productivity and revenue. By isolating hardware failures and providing spare capacity, it guarantees continuous power to essential gear and services.
• Scalable runtime with external battery modules (EBMs) — Extend runtime without replacing the core UPS. The Symmetra LX supports scalable runtime by adding EBMs, allowing you to tailor backup time to the criticality of your workloads. Start with a compact configuration and grow with your needs, ensuring graceful shutdowns, data integrity, and uninterrupted service during outages of varying durations. This scalability is particularly valuable for evolving networks, virtualized environments, and workloads with unpredictable power events.
• Transformer-based online double-conversion power protection — True online, double-conversion topology delivers isolated, conditioned output with low total harmonic distortion, excellent voltage regulation, and consistent frequency. This design shields sensitive servers, storage arrays, and networking equipment from input disturbances such as sags, surges, and outages. The integrated transformer provides robust isolation, improved fault tolerance, and clear separation between input and output grounds—enhancing safety and reliability in complex rack layouts.
• Space-saving tower form factor with versatile integration — The compact tower footprint is purpose-built for space-constrained server rooms and edge environments. Its modular architecture teams with a flexible upgrade path, allowing you to add batteries and power modules as your data center footprint grows. The result is a scalable, space-efficient solution that protects critical loads without forcing a larger, more expensive enclosure or a redesign of your existing rack or room layout.

how to install APC Symmetra LX 8kVA N+1 Tower, 208/240V

• Plan your placement: Choose a stable, well-ventilated location with adequate clearance for hot-swappable modules and airflow. Ensure access for maintenance and cable routing, and verify that power feeds, networking, and grounding meet local codes.
• Prepare the environment: Confirm ambient temperature and humidity ranges suitable for the UPS and EBMs. Install a dedicated grounded circuit for input power and separate grounding paths for utility, UPS, and protected loads to minimize interference.
• Mount and connect power modules: Insert hot-swappable power modules into the rack or tower chassis, following the vendor’s guidance for secure engagement. Connect the input power cable to the appropriate 208/240V feed, and verify that the N+1 redundancy configuration is achieved by adding spare capacity in the module set.
• Attach battery modules: Install EBMs in the designated bays, ensuring proper alignment and secure connections. If multiple EBMs are used, stagger installation to verify uniform charging and synchronization across modules.
• Configure the protection settings: Use the local front-panel interface or a connected management card to set output voltage (208 or 240V), enable the required protection features, and configure automatic shutdown behavior for protected loads during extended outages.
• Set up communications and monitoring: Install any required network management card, connect via USB or Ethernet, and enable SNMP or other monitoring protocols as needed. Register within your monitoring system to receive real-time status, alerts, and runtime estimates.
• Integrate with protected loads: Connect servers, storage, and network gear to the UPS output circuits. Route critical devices to passthrough outlets or busbars as configured. Ensure that critical loads are clearly identified to benefit from the UPS’s advanced protection features.
• Test and validate: Perform a controlled test by simulating a power event while monitoring voltage stability, switchovers, and shutdown sequences. Confirm that runtime, alarms, and notifications function as intended and that maintenance procedures are clearly documented for operators.

Frequently asked questions

• Q: What does N+1 redundancy mean for the Symmetra LX? A: N+1 redundancy means the system can tolerate the failure or maintenance of one module (power or battery) without impacting protected loads. This setup provides continuous uptime and minimizes the risk of an outage affecting critical equipment in space-constrained environments.
• Q: Can I upgrade runtime without replacing the UPS? A: Yes. Runtime is scalable by adding External Battery Modules (EBMs). You can start with a compact configuration and expand as your load or protection requirements grow, preserving investment while delivering longer backup times during outages.
• Q: Is the Symmetra LX suitable for data centers or edge deployments? A: It is designed for both use cases. Its compact, modular tower form factor makes it ideal for space-constrained server rooms and edge locations, while the scalable runtime and robust protection features support data center-grade reliability where uptime matters most.
• Q: What management options are available? A: The system supports a local front-panel interface and standard communications ports (USB, RS-232). An optional network management card enables remote monitoring via SNMP or other protocols, letting you track health, run-time, and status from anywhere on the network.
• Q: What loads can it protect? A: It protects critical IT infrastructure such as servers, storage arrays, virtualization hosts, and core network devices. By delivering clean, regulated power, it helps prevent data corruption, hardware failures, and unscheduled downtime across business-critical workloads.
