Power over Ethernet (PoE) is a technology that combines both data signals and electrical
power into a single Ethernet cable connection to enable
remote powered device operation. By eliminating the need
for separate data and power cables, PoE provides the

Cisco 2019 Software Defined Networking in Datacenter - ACI Solutions
Overview:
The Cisco Application Centric Infrastructure Fabric (ACI) fabric includes Cisco Nexus 9000 Series switches with the APIC to run in the leaf/spine ACI fabric mode. These switches form a “fat-tree” network by connecting each leaf node to each spine node; all other devices connect to the leaf nodes. The APIC manages the ACI fabric. The recommended minimum configuration for the APIC is a cluster of three replicated hosts. The APIC fabric management functions do not operate in the data path of the fabric.
