A power feed represents the distribution of power from a power panel to a particular device, typically a power distribution unit (PDU). The power port (inlet) on a device can be connected via a cable to a power feed. A power feed may optionally be assigned to a rack to allow more easily tracking the distribution of power among racks.
The power panel which supplies upstream power to this feed.
The rack within which this feed delivers power (optional).
The feed's name or other identifier. Must be unique to the assigned power panel.
The feed's operational status.
Additional statuses may be defined by setting
PowerFeed.status under the
FIELD_CHOICES configuration parameter.
In redundant environments, each power feed can be designated as providing either primary or redundant power. (In environment with only one power source, all power feeds should be designated as primary.)
If selected, the power feed will be treated as if a cable has been connected.
Electrical current type (AC or DC).
Operating circuit voltage, in volts.
Operation circuit amperage, in amperes.
Indicates whether the circuit provides single- or three-phase power.
The maximum safe utilization of the feed, expressed as a percentage of the total available power. (Typically this will be set to around 80%, to avoid tripping a breaker during heaving spikes in current draw.)
The power utilization of a rack is calculated when one or more power feeds are assigned to the rack and connected to devices that draw power.
