APC Smart-UPS On-Line 3kVA Rackmount 2U—120V, 9-Outlets (8x 5-20R + 1x L5-30R) with Network Card, Extended Runtime, and Rail Kit

When uptime matters, the APC Smart-UPS On-Line 3kVA rackmount unit stands guard over your most critical IT equipment. This 2U, 120V online UPS delivers pure sine wave power, unmatched reliability, and flexible runtime options to keep servers, network switches, storage equipment, and professional workstations operating through power disturbances. Built for IT professionals and network administrators, this UPS blends rugged hardware with smart management features to minimize downtime, protect data integrity, and simplify maintenance in data centers, colocation spaces, and enterprise server rooms.

• Pure online double-conversion power ensures continuous, clean output regardless of incoming power quality. With a 3 kVA rating and a practical 2.7 kW maximum output, it buffers against voltage sags, brownouts, and outages while maintaining stable voltages for sensitive equipment. The result is reliable performance for critical workloads, including virtualization hosts, databases, and high‑throughput servers.
• Flexible outlet configuration supports diverse equipment. Eight NEMA 5-20 receptacles plus one NEMA L5-30R provide plentiful, easily organized access for servers, edge devices, network switches, storage arrays, and auxiliary infrastructure. This layout enables clean cabling, better heat management, and straightforward outlet zoning for hot-swappable components.
• Robust input and protection features. The UPS uses a NEMA L5-30P input connection on standard 120V circuits, delivering scalable power in environments with varying loads. Automatic voltage regulation (AVR) maintains output quality when the utility voltage fluctuates, reducing battery wear and extending runtime for essential devices during short-term fluctuations.
• Integrated remote management and security. A built-in Network Management Card enables secure, remote monitoring over standard networks, with web-based dashboards, SNMP traps, and email or pager alerts. This makes it easy to track voltage, load, battery health, and runtimes, perform graceful shutdowns, and manage multiple UPS devices from a centralized console.
• Smart installation and maintenance footprint. The rack-ready design fits neatly into standard 19-inch racks with the included rail kit, simplifying deployment in data centers and server rooms. Extended runtime options, replaceable hot-swappable battery modules, and modular battery configurations offer scalable protection for mission-critical workloads without sacrificing performance during extended outages.

How to install APC Smart-UPS On-Line

• Plan the rack layout and power path. Confirm the UPS location in a cool, well-ventilated area with adequate clearance for airflow and service access. Verify that the 120V circuits can tolerate the UPS load and that space is available for the rail kit and cable management.
• Prepare the rack and rail kit. Install the included rail kit onto the rack rails according to the provided instructions. Ensure rails are level and securely fastened to support the weight of a full UPS plus connected equipment.
• Mount the UPS. Slide the 2U APC Smart-UPS into the rack rails, align mounting points, and fasten with the supplied hardware. Verify that the chassis is firmly seated and that there is no interference with other devices or cables.
• Connect the power and outlets. Attach the NEMA L5-30P input power cord to a dedicated 120V, 30A circuit or as specified by your facility standards. Route and connect the eight NEMA 5-20R outlets plus the L5-30R to the critical devices you intend to protect, ensuring loads do not exceed the unit’s rating (plan for a comfortable headroom).
• Configure management and startup. Install the Network Management Card if not pre-installed, connect the UPS to the network, and power it on. Use the management interface to set battery alarms, load limits, notification emails, and SNMP settings. Run a self-test from the front panel or the management software to verify proper operation and battery responsiveness.
