How it works
Each record describes one logical connection, not a live network scan. Cable labels and physical endpoints must be unique, ignoring letter case. A wall jack name should include its location and port, for example Office A-02. Optional patch-panel name and port must be entered together. Up to 96 connections are kept only in this open page; use Save JSON to keep your work. CSV exports prefix spreadsheet formula-like text with an apostrophe.
The formulaDevice port → optional wall jack → optional patch-panel port → switch port
Good to know
Does this configure or detect hardware?
No. This is a manual documentation tool. It does not discover devices, validate electrical continuity, configure switches or confirm VLANs.
Are the labels sized for a particular label sheet?
No. Print two matching labels per connection on plain paper, then cut and secure them appropriately. This is not a calibrated commercial adhesive-sheet template.
Where is the map saved?
Only explicit JSON downloads save a reusable map. There is no automatic browser storage or upload. Loading JSON replaces the current map after a confirmation when there are unsaved changes.
