8. Checking status/fault location
8.1 CHeCkING CoNNeCTIoN
The ‘Power’ LED must light green, and the ‘DSL Sync’ LED must light or flash
green. On some routers, you can also find an LED called ‘Internet’. When the
router is fully operational, this LED flashes or lights green. If the LEDs are not lit,
use the following router LED checklist:
If Then
The ‘Power’ LED
is not lit Check once again that everything is correctly connected. Check
that both the power outlet and the router are switched on (the
power button) and that the power supply is correctly connected.
If the ‘Power’ LED is still not lit, please contact Helpdesk on
tel. +45 80 80 80 90.
The ‘DSL Sync’
LED is not lit There is no connection to the ADSL central office. Disconnect the
power to the router for at least 60 seconds and then reconnect.
Wait 5-10 minutes while the router synchronises with the central
office. Connection has been established if the ‘DSL Sync’ LED lights
green. If not, please contact Helpdesk on tel. +45 80 80 80 90.
8.2 CHeCkING rouTer
You can now check whether the router is connected to the network. You can
also use this list as a quick reference should you experience problems with your
router at a later point.
• When the router is switched on, it runs a self-test. During the self-test, the
‘Power’ LED lights red.
• If the ‘Power’ or the ‘Internet’ LED switches from green to red after the self-
test, TDC is upgrading the router’s firmware. This could take 10-15 minutes,
during which period the router restarts several times. In this case, the router
must not be switched off or disconnected from the ADSL connection as this
may cause technical problems. At worst, the router may need to be repaired
before it can work again. If the ‘Internet’ LED lights red for more than 20 min-
utes, please contact Helpdesk on tel. +45 80 80 80 90.
• The ‘DSL Sync’ LED flashes when there is traffic between the router and TDC’s
network. The LAN 1, 2, 3, and 4 LEDs indicate whether there is traffic between
the router and connected computers and network equipment.
• Wireless Link indicates whether there is activity in the wireless network.
