Troubleshooting
If you are having problems, you may want to check the following:
• Make sure you are using the correct DC power supply.
-
ES7110: Use power supplies with 48VDC output.
- ES7110-VB: Use power supplies with 12-24VDC output.
• Select Ethernet cables with specifications suitable for your applications to set up your systems.
-
Ethernet cables are categorized into unshielded twisted-pair (UTP) and shielded twisted-pair (STP) cables.
- Category 3, 4, 5, and 6 Ethernet cables are suitable for systems with 10 Mbps transmission speed.
- For systems with 100 Mbps transmission speed, Category 5 and 6 Ethernet cables are the only suitable specifications
for this environment.
- You also need to make sure that the distance between any two nodes does not exceed 100 meters (328 feet).
- Use Alternative B Ethernet cabling on PoE ports.
• If the Power LED goes off when the power cord is plugged in, a power failure might have occurred. Check the power
output connection to see if there is any error at the power source. If you still cannot solve the problem, contact Comtrol
