Power Budget

The same faceplate canvas as Port Mapping, but for power: here you add power inlets, draw power cords from PDU outlets to device inlets, and see how loaded each PDU is. Network ports and cables are shown read-only (and network cables start hidden).

What you can do here

Task	How
Give a device a power inlet	5 (Power inlet), click the device
Draw a power cord	C (Power cord), click a PDU outlet, then a device inlet
Set how much a device draws	Select the inlet port, set Draw (W)
Record a PSU serial number	Select the inlet, set PSU serial number
Label a cord (e.g. feed A / B)	Select the cord, add Labels; filter by them under Power grid
Show network or power cables	Show/Hide network cables, Show/Hide power cables

A power cord always runs from exactly one PDU outlet to a power inlet. Selecting a network item here shows Read-only here. Network links and NICs are wired in the Port Mapping view.

The legend

The legend in the bottom-left corner reads:

• one row per PDU: its label, outlets in use / total (amber when all are used), a load meter, and the load against the capacity in kW. The meter turns amber above 80 % and red above 100 % of capacity;
• a footer: All N inlets fed, X of N inlets unfed, or a hint to add inlets when there are none.

How the load is calculated

Each inlet group's watts (its nameplate draw) is split evenly over its plugged-in cords and added to the PDU at the other end of each cord. A PDU's utilisation is that load divided by its Capacity (kW), set in the PDU template. A PDU without a capacity shows no meter.

In the DSL

Inlets are <Inlet> elements, outlets are <Phase> banks of a PDU, and cords are <PowerCable>:
