This is an example plan. Edit it freely, or start from empty racks.
Line width grows with the number of links. The badge on each leaf is down links to up links, red above 3 : 1; the bar is its ports in use.
A plan file (.json) opens as a new plan next to your others. A CSV inventory needs Rack, Position and Name or Type columns, like the CSV export. A cable schedule CSV (A and B device and port columns) adds its cables to the current plan.

Whoever opens this link gets their own copy of the plan. The plan is packed into the link itself; nothing is uploaded anywhere.
Each row prints on its own sheet: its racks with the cluster legend and title block, or its cabling from the front or the rear. Choose “Save as PDF” in the print dialog for a file.
Changes are saved automatically. Browser storage can be cleared, so export plan files you want to keep.
The types of devices, racks, cables and transceivers belong to this plan and travel with its file. Changes apply right away; Undo takes them back. Drag types to reorder them: the devices panel follows this order, new rows get the first rack type, and cables pick the first cable type that fits.
