Troubleshooting
Problem Suggested action
System LED does not light
up after the switch is turned
on.
Verify if the power cord is securely connected to the switch
and to a power strip.
Link LED does not light up
after an Ethernet cable is
attached.
1. Look for loose or faulty connections, make sure the
connections are secure. If these could not solve the
problem, try another cable.
2. Check the network cable used. Non-standard and
miswired cables can cause collisions and can seriously
impair network performance. Use of a category 5 cable
tester is recommended.
3. Check your network topology. Make sure that you have a
valid network topology. Common topology faults include
overlong cable and too many repeaters (hubs) between
end nodes. Also make sure that the network topology
contains no loops (i.e., only one active path is allowed
between every two nodes at any time). Loops can cause
broadcast storms and severely reduce your network
performance.
