Vertiv Liebert PSI5 Lithium-Ion N UPS 3000VA/2700W 120V Line Interactive AVR With SNMP Card

The Vertiv Liebert PSI5 Lithium-Ion N UPS is engineered for modern edge and distributed IT environments where uptime, space efficiency, and proactive management matter most. This 3 kVA UPS delivers dependable power protection for critical devices such as servers, networking equipment, and storage systems, all while leveraging advanced lithium-ion chemistry to extend battery life beyond traditional VLRA units. With its 120V line-interactive topology and automatic voltage regulation (AVR), the PSI5 stabilizes fluctuating power to protect sensitive electronics from outages, sags, and surges. The integrated SNMP card enables seamless remote monitoring and management, so IT teams can receive alerts, perform graceful shutdowns, and optimize energy usage without onsite visits. Coupled with a five-year factory warranty, the PSI5 Lithium-Ion N provides a compelling balance of performance, efficiency, and total cost of ownership for edge deployments that demand reliability and scalability.

• The PSI5 Lithium-Ion N combines robust power protection with dramatically longer battery life compared with traditional VLRA UPS units. This means fewer battery replacements, reduced maintenance, and lower lifecycle costs, even in harsh edge environments where uptime is paramount. Its compact footprint and lighter weight help maximize rack density while preserving floor space for critical IT gear. The lithium-ion chemistry also supports faster recharge and improved cycle resilience, ensuring your data path stays protected during both brief flickers and longer outages.
• Line-interactive AVR technology with automatic voltage regulation maintains a steady 120V output even when the incoming supply experiences sags or minor surges. This minimizes stress on connected equipment, preserving data integrity and reducing the risk of unexpected shutdowns. In edge deployments where utility quality can vary, AVR acts as a first line of defense, delivering clean, stable power to keep servers, switches, and storage devices running smoothly.
• SNMP management card included for remote visibility and control. Monitor live status, battery health, load, and events from anywhere in your network management system. The PN-based SNMP interface enables straightforward integration with DCIM tools and virtualization platforms, empowering IT teams to automate shutdown sequences, log power events, and fire proactive alerts before a fault escalates into downtime.
• Stable, scalable lithium-ion battery technology offers superior life expectancy and a smaller environmental footprint. The Li-ion battery chemistry reduces maintenance intervals and lowers total cost of ownership, while delivering reliable runtime for critical workloads. This makes the PSI5 N particularly well-suited for distributed IT nodes, edge data centers, and remote sites where service intervals are tight and uptime is essential.
• Backed by a five-year factory warranty, the PSI5 Lithium-Ion N combines enterprise-grade reliability with Vertiv’s renowned service support. The warranty reflects the confidence in the unit’s construction, battery performance, and long-term resilience in challenging environments. With Vertiv’s global support network, customers gain peace of mind that technical assistance, spare parts, and upgrades are readily available as your IT footprint evolves.

How to Install Vertiv Liebert PSI5 Lithium-Ion N UPS

Before you install, ensure the UPS is placed in a well-ventilated area with adequate clearance for cooling and service access. Verify the electrical circuit you plan to use can handle the load and that the outlet matches the 120V input specification. Prepare your management environment by confirming you have access to the SNMP management card and corresponding software or DCIM integration tools. With safety in mind, power down and disconnect any equipment you intend to protect before wiring, and keep the installation area free of excessive dust or moisture.

Step 1: Unpack and inspect the unit for any shipping damage, including the SNMP card and cabling. Step 2: Position the UPS on a solid surface or rack that accommodates its footprint and allows for proper airflow. Step 3: Connect the included SNMP management card to the designated interface and attach to your network according to the user guide. Step 4: Connect the UPS to a dedicated 120V outlet, ensuring grounding and bonding are in place to prevent ground loops and improve protection. Step 5: Attach your critical equipment (servers, switches, storage devices) to the UPS output outlets, ensuring the total connected load does not surpass the 2700 W rating. Step 6: Power on the UPS and use the management interface to verify battery health, runtime estimates at your expected load, and alert configurations. Step 7: Configure automatic shutdown policies and integration with your virtualization or backup software to ensure graceful termination of services during extended outages. Step 8: Perform a simulated outage to confirm the system responds correctly and captures events in your monitoring platform. Step 9: Document the installation and establish routine checks for battery health, firmware updates, and SNMP alerts to sustain long-term reliability.

Operational tips: Keep the UPS firmware and SNMP card updated to ensure compatibility with evolving IT environments. Maintain adequate airflow around the unit and avoid stacking equipment directly on top of the UPS, which could impede cooling. Regularly review battery health and runtime projections to plan proactive maintenance or replacements, especially in edge sites where accessibility can be limited. By following these steps and leveraging the PSI5’s advanced battery chemistry and management features, you can maximize uptime and protect mission-critical workloads without complicating your IT footprint.
