Architectural Overview and Functional Design
The Cisco SKY-PC-SWI= is a 1U rack-mountable power distribution switch engineered for 48VDC power systems in enterprise and hyperscale environments. Integrating 32 individually controllable outlets with 0.1A resolution monitoring, this unit enables granular per-port power management for Cisco UCS, Nexus, and Catalyst platforms. Its TIA-942 Tier IV compliant design supports dual-feed power architectures with <1ms failover capability.
