Troubleshooting
This chapter gives information about troubleshooting your Model RH340 Internet Access ISDN
Router. After each problem is described, instructions are provided to help you diagnose and solve
the problem.
Basic Functioning
After you turn on the 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. This
self-test includes turning on power to all of the ISDN LEDs sequentially. After this self-test, the
Test LED should begin to blink at a rate of about 0.5 Hz. After approximately one minute, the Test
LED is no longer lit. If these steps do not occur, refer to
“Test LED
,” on
page 6-2
.
If an active Ethernet device is connected to a LAN port, the LAN LEDs for that port should be lit.
If the LAN LEDs are not lit, refer to
“LAN Link LED
,” on
page 6-2
.
If your router has been configured, the ISDN D LED should be lit within the first two minutes
of operation. If not, refer to
“Troubleshooting the ISDN Line
,” on
page 6-2
.
LEDS
If no LEDs are lit when the power to your router is 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. Check that the power switch to the router is in the on position. If the error persists,
you have a hardware problem. Unplug the router and contact technical support.
