2.4 POWER/ETHERNET (continued)
2.4 POWER/ETHERNET
The LX is powered by Power over Ethernet (PoE), which is provided by an inline injector.
This requires a special PoE power supply. The LX Ethernet port supports automatic
MDI/MDI-X. This allows it to handle regular or crossover Ethernet cables.
In most installations, the following specifications should apply.
Input Requirements: 9—28 Vdc (+v for hi/lo margin on input); 5000 W transient suppression
(clamp off over-voltages, spikes and surge the output voltages).
Output Requirements: 18—48 Vdc @ 20 W minimum (1.1 A @ 18 Vdc) (The higher the output
voltage, the further the power box can be moved remotely from the LX).
