how to install Vertiv Liebert PSI5 UPS

• Unpack the unit and verify that all components, including the RDU120 NIC, are present and intact. Inspect the chassis for any shipping damage and ensure you have the appropriate mounting rails for your rack.
• Mount the PSI5 securely in your standard 19-inch rack using the supplied rails or brackets. Confirm that there is adequate clearance for ventilation and cable organization.
• Connect your critical devices to the UPS outlets, ensuring total load stays within the 990 W rating. Leave some headroom for in-rush and startup currents of connected equipment.
• Connect the UPS input power to a dedicated 120 VAC power circuit. Ensure the circuit is properly grounded and that electrical safety guidelines are followed.
• Install the RDU120 NIC card for network management. Connect the UPS to your network and configure alerts, monitoring, and shutdown policies using your preferred management software or the PSI5’s built-in interface.
• Power on the UPS and perform a basic configuration check. Verify communication with the NIC, run a self-test, and confirm that voltage regulation and surge protection are functioning as expected.

Frequently asked questions

• What does the PSI5 protect? The Vertiv Liebert PSI5 protects servers, network switches, storage devices, and other critical IT equipment from power outages, brownouts, sags, spikes, and transient disturbances, helping ensure data integrity and uptime.
• What comes with the inclusion of the RDU120 NIC? The RDU120 NIC provides remote monitoring and management capabilities, including alerts and graceful shutdowns across your network, enabling proactive power protection without onsite intervention.
• Can the PSI5 be mounted in a standard rack? Yes. The PSI5 is designed for standard 19-inch racks, facilitating compact, organized, and accessible deployment in IT cabinets and data centers.
• How do I monitor the UPS status? Use the RDU120 NIC for network-based monitoring. You can also access status information via compatible software or the local management interface for real-time measurements, event logs, and shutdown configuration.
• What is the typical runtime for 1100 VA / 990 W loads? Runtime varies with load. At lighter loads, you can expect longer run times; at heavier loads near the 990 W rating, runtime will be shorter. The PSI5 is designed to provide enough time for orderly shutdowns during short outages and to bridge longer outages with reduced loads.
