Troubleshooting
This chapter gives information about troubleshooting your Model RM356 Modem Router. After
each problem description, instructions are provided to help you diagnose and solve the problem.
Basic Functioning
When you turn on power to the router, the PWR LED lights. If the PWR LED does not light, refer
to the next section, “LEDS.” After the PWR LED lights, the router performs a self-test for 15
seconds. After this self-test, the Test LED should begin to blink at a rate of about 0.5 Hz. After
initialization is complete, the Test LED will turn off.
If an Ethernet connection is made to any LAN port, the LAN LED for that port number should be
on. If the LAN LED is off, refer to “
LAN Link LED,” on page 10-1.
LEDS
If all LEDs are off when your router is turned on, make sure that the power cord is properly
connected to your router and that the power supply adapter is properly connected to a functioning
power outlet. If the error persists, you have a hardware problem and should contact technical
support.
LAN Link LED
If the LAN LED for any LAN port does not light when the Ethernet connection is made to that
port, check the following:
• Physical Ethernet cables
Make sure that the connections are secure at the router and at the attached workstation.
