Troubleshooting
Make sure the equipment is installed according to the manufacturer's installation guide.
Confirm RJ45 cable order meets EIA/TIA 568A or 568B standard.
Each PoE port can provide maximum power of 30W. Do not connect equipment requiring
over 30W.
Replace the equipment with a proper functioning 28 Port PoE Ethernet Switch to check
if the equipment is damaged.
Please contact UltraTech Support at 833-574-9124, or contact the installing company.
Total PoE power between all 24 PoE ports is limited to 360W.
Plug Producing Method
Instruments to be used: wire crimper and network tester. Wire sequence of RJ45
plug should conform with EIA/TIA568A or 568B.
1. Remove 2cm of the insulating layer and bare 8 pairs UTP cable.
2. Separate the 8 pairs of UTP cable and straighten.
3. Line up the 8 pieces of cables per EIA TIA 568A or 568B.
4. Cut off the cables to leave 1.5cm bare wire.
5. Plug 8 cables into RJ45 plug make sure each cable is in each pin.
6. Use the wire crimper to crimp.
7. Repeat above steps to make additional ends.
8. Use network tester to test the cable.
