Cabling
1. Verify that the cable type is correct. Be sure RJ-45 cable connectors are securely seated in the required ports. Use
100
Ω
straight-through cables for all standard connections. Use Category 5 cable for 100/1000Mbps Fast Ethernet
connections, or Category 3, 4 or 5 cables for standard 10Mbps Ethernet connections. Be sure RJ21 phone wiring,
use 18~26 gauge.
2. Make sure all devices are connected to the network. Equipment any have been unintentionally disconnected from
the network.
3. When cascading two devices using RJ-45 station ports at both ends of the cable (24 ports VDSL IP DSLAM)
supports auto MDIX), without crossover cable can be used.
Physical Configuration
If problems occur after altering the network configuration, restore the original connections, and try to track the
problem down by implementing the new changes, one step at a time. Ensure that cable distances and other physical
aspects of the installation do not exceed recommendations.
System Integrity
As a last resort verify the switch integrity with a power-on reset. Turn the power to the switch off and then on several
times. If the problem still persists and you have completed all the preceding diagnoses, then contact your dealer for
assistance.
