Chapter 3 Cabinet Installation
3.1 Introduction
3.1.1 About the Cabinet
A cabinet is a basic unit for LED engineering installation in which LED modules are neatly mounted
on a metal sheet (cast aluminum) box, with a built-in independent receiving card and switching
power supply, an engineering installation structure, and independent display.
3.1.2 Load Capability of the Cabinet
Load Capability of Network Interfaces
The load capability of a single network interface of the sending card is limited. You can calculate
the max load of a single network interface by the following formula.
Max Load of a Network Interface = Pixel Capacity of a Network Interface/Cabinet Resolution
Example
If equipped with a sending card of 650,000 pixels, the max load of a single network interface for a
P1.2 cabinet of 480 × 270 resolution is 5 cabinets.
Note
You can choose sending cards of different pixels and cabinets of different resolution, and
calculate the load capability by the formula.
Load Capability of Power Cords
The load capability of a single power cord is limited. You can calculate the max load of a single
power cord by the following formula.
Max Load of a Single Power cord = Power of the Cord/Power of the Cabinet
Note
You can choose power cords and cabinets of different specifications, and calculate the load
capability by the formula.
