# Power the Ethernet board for the GigE cameras

Aim

To power the GigE cameras without the PoE injectors.

This topic applies when you have a 4-port Ethernet interface board to connect the GigE cameras to your EthoVision XT computer.

Prerequisites

▪You have installed a 4-port Ethernet board. See Install an Ethernet board for GigE cameras

Procedure

Power cable and connector types vary between computers. Many computers have a SATA 15-pin power connector. Use an adapter cable with a 4-pin female Molex connector at one end and a SATA 15-pin connector at the other end.

If a separate cable is not available, you can disconnect the cable that from the power supply (PSU) goes to the hard disk (HD) and connect that end to a Y adapter cable, whose other two ends go to the hard disk and to the Ethernet board:

Notes

▪When your Ethernet board is not powered, you must power the camera using a Gigabit Power-over-Ethernet injector (PoE injector; one per camera). The data transfer rate of the PoE injector must be 1 Gbit/s. See Connect the GigE camera to the PC
