Connect the Ethernet Cable
The vision system's ENET connector provides the Ethernet connection for network
communications and supplies power to the vision system.
1. Verify that the PoE injector or PoE switch is unplugged and not receiving
power.
2. Connect one end of the Ethernet cable to the PoE switch or PoE injector.
CAUTION :
l
The Ethernet cable must be shielded. Cognex strongly
recommends Cat 6 or Cat 7 Ethernet cables with S/STP
shielding.
l
The Ethernet cable shield must be grounded at the far end. If
using a PoE injector, a ground wire should be connected
from the Ethernet shield at the PoE injector to frame ground
or Earth ground, and a digital voltmeter used to validate the
grounding. If using a PoE switch, it should have a metal case,
with the case grounded to frame ground or Earth ground.
3. Connect the other end of the cable to the vision system's ENET connector. If
using a compatible horizontal screw-locking Ethernet cable, use a screw
driver to tighten the connector screws until snug, to secure it to the vision
system. Screws must be tight to assure a reliable connection.
4. Restore power to the PoE injector or PoE switch's power supply, and turn it
on if necessary.
