Vertiv Geist RTS VA4N2100 - Rack Transfer Switch RPDU (10 NEMA 5-20R)

In a data center, uptime is everything. The Vertiv Geist RTS VA4N2100 is a versatile rack transfer switch integrated with a rack power distribution unit (RPDU) that is engineered to deliver dependable, redundant power to critical devices in busy server rooms and network closets. This 20A, 120V, single‑phase unit provides ten NEMA 5-20R outlets to support a range of gear from servers and switches to telecom appliances and storage arrays. The VA4N2100 delivers up to 1.9 kW of continuous power, making it an ideal solution for environments that demand reliable power distribution without sacrificing space or manageability. Its built‑in transfer switch ensures power continuity by automatically switching between input sources, so a fault on one circuit does not interrupt operations for connected equipment. Designed for rack mounting in standard 19-inch racks, the VA4N2100 helps IT teams reduce downtime, simplify power distribution, and maintain clean, organized cabling within a compact footprint. With rugged construction and clear labeling, it is ready to perform in data centers, edge locations, and IT closets where reliability matters most. Whether you are provisioning a new rack, upgrading an existing setup, or consolidating power for a dense array of devices, the VA4N2100 provides a solid foundation for uptime, efficiency, and organized power management.

• Redundant Power Path: The VA4N2100 features an integrated transfer switch that continuously monitors input sources and can switch to an alternate source for connected devices, delivering uninterrupted power during outages or source faults. This redundancy helps protect critical gear from transient events and reduces the risk of unplanned downtime.
• Ten NEMA 5-20R Outlets: Provides ten standardized outlets for servers, switches, storage, and other rack-mounted gear, enabling you to consolidate power distribution in a single, organized RPDU and simplify cable routing within the rack.
• High-Efficiency Electrical Design: Rated for 20A at 120V with a maximum load of 1.9 kW, this RPDU balances capacity with efficiency, helping you optimize energy use in dense rack environments while keeping heat generation manageable.
• Rugged, Rack-Mountable Construction: Built to endure the rigors of data center life, the VA4N2100 is designed for standard 19-inch racks with a sturdy enclosure and reliable mounting hardware that stands up to routine maintenance and handling.
• Easy Deployment and Maintenance: Clear labeling, straightforward wiring, and simple status indicators help technicians install, monitor, and service the unit quickly, reducing maintenance time and human error.
