Power Tracking

Power Panel

A power panel represents the distribution board where power circuits – and their circuit breakers – terminate on. If you have multiple power panels in your data center, you should model them as such in NetBox to assist you in determining the redundancy of your power allocation.

Power Feed

A power feed identifies the power outlet/drop that goes to a rack and is terminated to a power panel. Power feeds have a supply type (AC/DC), voltage, amperage, and phase type (single/three).

Power feeds are optionally assigned to a rack. In addition, a power port – and only one – can connect to a power feed; in the context of a PDU, the power feed is analogous to the power outlet that a PDU's power port/inlet connects to.

Info

The power usage of a rack is calculated when a power feed (or multiple) is assigned to that rack and connected to a power port.

Example Power Topology

Below is a simple diagram demonstrating how power is modeled in NetBox.

Note

The power feeds are connected to the same power panel for illustrative purposes; usually, you would have such feeds diversely connected to panels to avoid the single point of failure.
