Vertiv SmartCloset 42U Online 3 kW UPS 120V | Rack Mount, Enterprise

Consolidate power protection and rack deployment in one enclosure designed for serious infrastructure. Vertiv SmartCloset combines a 42U rack format with online UPS architecture and 3 kW of protected output, helping keep network, security, and edge systems running through power disturbances. The 120V design fits common branch-circuit environments, while the included networking card adds the visibility operations teams expect when uptime matters. This is the kind of platform that reduces the number of separate parts you have to source, install, and maintain. Instead of pairing a rack, UPS, and management add-ons from different lines, SmartCloset brings the core pieces together in a single deployment path. That matters when you need predictable installation, cleaner cable management, and fewer points of failure. For IT teams supporting firewalls, switches, and other rack-based systems, the value is in control. Online topology conditions power continuously, helping isolate connected equipment from line irregularities before they become service interruptions. The result is a more disciplined power layer for locations where downtime is expensive and space is limited.
