Cabling and power Connect cables and catch power problems

Here's how to plan cabling and power.

Open Cabling. At estate level it summarises every recorded cable: eighty-four, thirteen between racks.

Open the core rack, choose Connect cable, and pick port seven on the first spine switch as the source.

Type in the destination name shown on screen. Thirty-one of its thirty-six ports are free.

Pick a free port, then open Cable details and type a label for the cable.

Press Connect cable. The new cable appears against that spine port, ending on the leaf switch.

To check a longer run, open the GPU rack and choose Open complete path on a cable leaving the leaf switch.

The path runs through the patch panel to the network card on the GPU server, about four metres in total. This cabling already exists in the example.

Now power. This rack has about eighteen point six kilowatts of headroom. Open the core rack and select the first spine switch.

Every device should be fed from two PDUs. Remove one feed and Railyard flags it: an amber triangle appears on the device, and the warning says there's no A and B diversity.

Open Review. The badge counts the warning, and the panel lists it, with a one-click fix.

Or restore the feed yourself: choose Connect inlet on the second power supply, pick the B-side PDU, then outlet one. The spine switch shows two PDU feeds again, and headroom stays at about four and a half kilowatts.

Open Review again and the warning has gone: only the informational notes remain.

Next, you'll draw the network as a topology. Try it free at railyard.sh.
