Any AXT620 switch (but only one) can be set as the DHCP server
•
Each networked device needs an individual connection to the switch

Troubleshooting
Incorrect connections
The switch port can automatically detect straight or crossover cable when linked with other Ethernet devices. For the RJ-45 connector, STP cable,
10/100Mbps port use 2-pairs twisted cable.
Faulty or loose cables
Look for loose or faulty connections, and make sure the connections are snug. Lastly, try a different cable.
Non-standard cables
•
Non-standard and incorrectly-wired cables can cause network collisions and other problems, and can impair network performance. A category 5e/6-
cable tester is a recommended tool for network installation.
•
RJ-45 ports: Use shielded twisted-pair (STP) cable for RJ-45 connections. Be sure that the length of any twisted-pair connection does not exceed 100
meters (328 feet).
Improper Network Topologies
It is important to make sure that you have a valid network topology. Common topology faults include excessive cable length and too many repeaters
(hubs) between end nodes. In addition, you should make sure that your network topology contains no data path loops. Between any two end nodes,
there should be only one active cabling path at any time. Data path loops will cause broadcast storms that will severely affect your network performance.
