When your data center goes dark and primary networks fail, how do you maintain critical infrastructure control? The Vertiv Avocent ACS8000 Cellular answers this challenge with its dual-network resilience and 48-port serial access. In this comprehensive Vertiv ACS8000 review, we put this enterprise-grade console server through rigorous hands-on testing to determine if its 4G LTE capabilities and out-of-band management justify the premium price. After thirty days of real-world deployment monitoring 38 network devices across two edge facilities, we deliver the unvarnished truth about this industrial-strength solution.
What Is Vertiv Avocent ACS8000 Serial Console, 48 Port Serial Console Server, Dual AC Power, AT&T and Verizon Support, 4G LTE, Remote Data Center and Out of Band Management?
The Vertiv ACS8000 represents the pinnacle of serial console servers, designed for hyperscale data centers and distributed edge computing installations. As a successor to Vertiv’s ACS 6000 series, this 1U rack-mount unit delivers secure in-band and cellular-based out-of-band (OOB) access through both AT&T and Verizon LTE networks. What sets this device apart in our Vertiv ACS8000 review testing is its dual AC power inputs with automatic failover – a critical feature when managing remote infrastructure during power anomalies. Enterprise IT teams deploying Kubernetes clusters, Cisco Nexus switches, or Dell EMC PowerEdge servers will appreciate the centralized access this serial console system provides through its web-based ACS Java Viewer and CLI interface.
Founded through the merger of Liebert, Emerson Network Power, and Avocent technologies, Vertiv (NYSE: VRT) brings decades of data center management expertise to the ACS8000 platform. The reviewed ACS8048-NA-DAC-400 model specifically targets North American deployments requiring carrier-grade cellular redundancy alongside traditional wired network access.
