Troubleshooting
Symptom
Solution
Power indicator does not
light up (green) after power
on.
Step 1. Check the power cord by
plugging into another device
and see if it is functioning
properly.
Step 2. If these measures fail to
resolve the problem, have the
power supply replaced by
your supplier.
The LEDs show off after
cable is connected.
Step 1. Make sure you are connected
to the Hub.
Step 2. Verify that the other end of
the UTP/STP cable is
connected to the Hub which
is powered on and on-line.
Step 3. Check the UTP/STP cable is
connected to RJ-45 port not
the Uplink port.
