Vertiv Liebert PSI5 UPS - 3000VA Line Interactive, Rack/Tower, with NIC

The Vertiv Liebert PSI5 UPS delivers dependable, scalable power protection for small data environments, media closets, and compact racks. With a 3000VA (2700W) capacity and a line-interactive topology, this smart UPS guards critical electronics and sensitive servers from power disturbances, while automatic voltage regulation (AVR) smooths fluctuating mains without consuming valuable battery runtime. The built-in Network Interface Card (NIC) enables remote monitoring and management, so you can proactively protect workloads, optimize uptime, and safeguard data integrity across distributed IT assets.

• Power protection for media closets, small racks, and active PFC power supplies, ensuring clean, reliable backup power for essential equipment.
• Line-Interactive topology with AVR maintains steady voltage during brownouts and overvoltages, reducing battery wear and extending runtime when mains quality is imperfect.
• Comprehensive safeguard against outages, surges, and power disturbances that can lead to data loss,崩溃, or equipment damage in sensitive electronics.
• Rack/Tower convertible design provides flexible installation in IT closets, 19-inch racks, or standalone work areas to fit evolving infrastructure needs.
• Integrated Network Interface Card (NIC) for remote monitoring, alerting, and centralized power management across your networked devices.

How to install Vertiv Liebert PSI5 UPS

• Plan the installation location: Choose a cool, dry, well-ventilated area with adequate clearance around the unit. If mounting in a rack, ensure the rack is stable and rated for the weight of the UPS and connected equipment. If using as a standalone tower, place it on a sturdy surface away from dust and moisture.
• Prepare the loads: Identify critical devices to connect to the UPS outlets (servers, network gear, storage, and other sensitive electronics). Distribute loads to stay within the 2700W maximum output rating and leave a buffer for surge events.
• Power and cabling: Plug the UPS into a dedicated AC outlet matching the unit’s input requirements. Route power cables securely and avoid running power and data cables together to minimize interference. Connect the NIC to your network using standard Ethernet cabling for remote monitoring.
• Connect the loads: Attach your protected devices to the UPS output outlets. For devices that require uninterrupted shutdown, ensure they are configured to communicate with the UPS via the NIC or software utility to receive a proper shutdown signal during outages.
• Configure and verify: Power on the UPS and access the management interface or software provided with the NIC. Set alert preferences, shutdown policies, sensitivity to voltage fluctuations, and automatic test routines. Run an initial battery test and verify that all connected equipment receives the expected protection and that alarms are properly logged.

Frequently asked questions

• What loads can this UPS protect? The Liebert PSI5 supports essential IT equipment in small racks and media closets, including servers, switches, storage devices, and other sensitive electronics with a capacity of up to 2700W for safe, reliable backup power.
• Can I use this UPS in a rack and in a tower? Yes. The PSI5 is designed as a convertible unit that can be mounted in a standard 19-inch rack or deployed as a standalone tower to fit different deployment scenarios.
• Does it offer remote monitoring? Yes. The UPS includes a built-in NIC that enables remote monitoring and management so you can track voltage quality, battery health, load levels, and event notifications across your network.
• What is the benefit of line-interactive topology? Line-interactive UPS systems regulate voltage with AVR, correcting minor deviations without draining the battery. This improves power quality, reduces unnecessary battery usage, and provides faster, more reliable protection during fluctuations.
• How do I maintain or replace batteries? The PSI5 is designed for reliability and serviceability; batteries can be replaced or serviced through Veritiv/Vertiv support options. Regular battery health checks and periodic calibration help ensure optimal runtime when critical events occur.
