Cabling

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.

Outlets or keystones to terminate on the panel (one per network drop).

Extra ports for future growth. Typical 25 %.

Ports per panel. 48p panels save U but crowd the cabling.

24p is usually 1U; 48p comes in 1U or 2U depending on model.

Horizontal manager or comb under each panel to dress the patch cords.

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.
