Patch Panel Planner
Enter the network drops, panel density (24/48 ports) and growth reserve and I compute the panels needed, the ports and the rack space (U), including cable managers.

Comparison by density
| Density | Panels | Ports | Free | Rack U |
|---|
The selected density is highlighted · U computed with the current height and manager.
How it is computed · patch panel sizing
1. The reserve is added to the drops:
ports = ceil(drops × (1 + reserve/100)). With 96 drops and 25 %,
96 × 1.25 = 120 target ports.
2. Panels come from the density:
panels = ceil(ports / density). With 48p panels,
ceil(120 / 48) = 3 panels.
3. Ports actually installed are
panels × density and free ports are
installed − drops (spare capacity available today).
4. Rack space adds the panel height plus its manager:
U = panels × (Upanel + Umanager). With 3 panels of 1U and 1U of manager
each, 3 × (1 + 1) = 6U.
5. The reserve is a design recommendation: growing later costs more than leaving spare ports today. Adjust it to the site's expected growth.
