UPS battery cabinet APC Symmetra LX 5U, sealed lead‑acid VRLA, black, 114.1 kg

The APC Symmetra LX 5U UPS battery cabinet provides hot‑swappable sealed lead‑acid (VRLA) battery modules in a compact 5U form factor. Designed to extend runtime for Symmetra LX systems, this black cabinet is intended for modular power architectures in data centres, server rooms and other critical infrastructure. The unit supports parallel battery module configuration to increase availability and is suitable for environments that require scalable, serviceable backup power.

Advantages

The cabinet’s modular design increases adaptability, allowing integration into varied IT environments and enabling capacity expansion as needs change. Hot‑swappable, user‑replaceable battery modules minimise downtime by permitting battery replacement without interrupting the protected load. Parallel connection of battery modules provides redundancy to improve overall system availability. Plug‑and‑play external battery capability allows straightforward runtime extension when additional backup duration is required.

Suitable for

• Data centres and colocation facilities requiring scalable UPS runtime
• Server rooms and rack environments with Symmetra LX systems
• Network closets and telecom cabinets needing hot‑swap battery replacement
• Critical infrastructure where redundant power and maintainability are essential

How to use

Install the cabinet in a compatible 19‑inch equipment rack according to the Symmetra LX installation guidelines and local codes. Connect the cabinet to the Symmetra LX power frame using the manufacturer’s recommended electrical and communications interfaces. Populate the cabinet with VRLA battery modules as required for the desired runtime. When replacing batteries, follow the hot‑swap procedure to remove and insert modules without powering down protected equipment; ensure only trained personnel perform battery service and observe safety and disposal regulations for lead‑acid batteries.

Usage recommendations

Locate the battery cabinet in a temperature‑controlled, ventilated rack area to maximise battery life and performance. Follow the UPS and battery manufacturer’s maintenance schedule, perform regular visual inspections, and test runtime under load after installation or any maintenance. Use compatible battery modules and perform replacements promptly when end‑of‑life indicators are detected to maintain redundancy and availability.
