Vertiv Liebert PSI5 UPS - 2200VA Line Interactive, Rack/Tower, with NIC

The Vertiv Liebert PSI5 UPS delivers robust power protection for small to mid-size equipment rooms, media closets, and compact server racks. With a 2200VA capacity (1920W), this line‑interactive UPS is designed to safeguard critical electronics from power disturbances—variations in voltage, outages, sags, and surges—that can lead to data loss, hardware damage, or downtime. The PSI5 is engineered for devices that rely on steady, clean power, including active Power Factor Correction (PFC) power supplies, network gear, storage arrays, and media equipment. Its compact rack/tower form factor makes it ideal for flexible deployment in mixed environments, whether you’re upgrading an existing rack, setting up a new small data closet, or protecting a compact server room. The embedded NIC enables proactive remote monitoring and graceful shutdown, helping IT staff stay ahead of potential issues without being physically on-site. In short, the PSI5 is a dependable, enterprise-grade solution that blends performance with simplicity for peaceful, continuous operation of mission-critical electronics.

• Robust 2200VA / 1920W capacity for essential equipment — The PSI5 provides substantial backup power for critical devices such as routers, switches, NAS appliances, small servers, workstations, and media players. With ample VA and W ratings, it sustains devices during short outages and helps prevent data corruption by allowing orderly shutdowns when green power becomes scarce. The high capacity is paired with efficient management so you can protect multiple devices in a compact footprint without needing a separate, larger UPS. This makes the PSI5 a practical choice for media closets and small rack environments that require reliable uptime and data integrity.
• Line-Interactive topology with AVR for clean, reliable output — The PSI5 uses a line-interactive architecture that prioritizes battery life and efficiency while delivering a stable, clean output waveform. Automatic Voltage Regulation (AVR) corrects common power fluctuations without drawing on battery power, extending runtime and reducing wear on connected equipment. This means your connected devices experience fewer voltage distortions, better protection against sags and surges, and smoother operation during electrical disturbances common in commercial and residential environments. For networks and storage gear, AVR helps preserve performance and avoids unnecessary reboot cycles caused by minor outages or brownouts.
• Rack/Tower convertible design for flexible deployment — Whether you’re installing in a standard 19-inch rack or placing the unit on a shelf or the floor, the PSI5 adapts to your space. The rack-mount hardware and the tower-friendly form factor give you the freedom to configure placement to maximize airflow, accessibility, and cable management. This versatility is particularly valuable in mixed environments where existing infrastructure may evolve—from a single-purpose room to a multi-ruite data closet—without needing to replace the UPS as your layout changes.
• Integrated NIC for remote monitoring and proactive management — The UPS ships with a built-in network interface card (NIC) that enables remote monitoring, status polling, and graceful shutdowns over the network. Paired with Vertiv’s Liebert software ecosystem and standard protocols, IT staff can receive alerts, review real-time health metrics, and script automated shutdowns for connected devices when power conditions warrant. This capability reduces on-site service needs, improves incident response times, and helps protect business-critical workloads even when personnel aren’t physically present at the equipment location.
• Smart protections and software integration for sustained uptime — Beyond battery-backed power, the PSI5 provides multiple layers of protection to safeguard connected equipment. It defends against voltage irregularities, protects against surges, and supports orderly shutdowns during extended outages. The integrated management features work with common IT software to automate notifications, events, and battery management, enabling more predictable maintenance windows and fewer surprises during peak business hours. The combination of hardware resilience and software visibility makes the PSI5 an appealing choice for small data closets, network corners, and environments where uptime is essential.

how to install Vertiv Liebert PSI5 UPS

Unbox and inspect the unit for any shipping damage, and verify that all mounting hardware is included. Decide whether you will rack-mount or place the UPS in a tower configuration in your space. If rack-mounting, install the included mounting brackets and slide the unit securely into the 19-inch rack, making sure there is adequate clearance for cooling and cable access. Position the UPS in a well-ventilated area away from heat sources and ensure it is level and stable. Ground the unit properly according to local electrical codes and the manufacturer’s installation guide. Connect the UPS to the building mains using the appropriate circuit breaker and power cord, ensuring the input voltage matches the system requirements. Connect your protected equipment to the UPS output receptacles, keeping high-load devices on the UPS to optimize battery usage. Attach the NIC network interface to your network and configure it with the Liebert software for monitoring, alerts, and graceful shutdown policies. If you plan to use USB or serial management, connect those interfaces as well and install the supported management software on your monitoring workstation. Finally, perform a self-test from the UPS front panel or through the management software to verify proper operation, battery health, and communication with connected devices. Regularly review firmware and software updates from Vertiv to maintain compatibility with your IT environment and ensure ongoing protection against power anomalies.

Frequently asked questions

• Q: Is the PSI5 suitable for rack mounting?

  A: Yes. The Vertiv Liebert PSI5 is designed as a rack/tower convertible UPS, allowing convenient installation in standard 19-inch racks or placement as a standalone unit in a room or cabinet with appropriate ventilation and stability.

• Q: What kind of management is included with the PSI5?

  A: The PSI5 includes an integrated NIC for remote monitoring and management. This enables proactive alerts, status dashboards, and graceful shutdowns via Vertiv software and standard network protocols, reducing on-site service needs and improving uptime visibility.

• Q: Can AVR help reduce energy costs?

  A: Automatic Voltage Regulation (AVR) stabilizes output without draining the battery, protecting equipment from minor voltage fluctuations and reducing unnecessary battery cycling. This improves efficiency, extends battery life, and provides smoother operation for sensitive electronics.

• Q: What devices should I protect with the PSI5?

  A: The 2200VA UPS is well-suited for media closets, small racks, networking gear (routers, switches, access points), storage devices, and other critical electronics that require clean, continuous power and controlled shutdowns during outages.

• Q: What maintenance is required?

  A: The PSI5 uses a sealed lead-acid battery designed for maintenance-free operation. Battery health should be tested periodically via the management software, and battery replacement should follow the manufacturer’s recommendations to maintain optimal runtime and protection.
