Troubleshooting installation
If you are having problems installing the router, try one or more of the
following:
No LEDs light
If none of the LEDs on the front panel of the router light up the most likely
reason is that the router is not receiving mains power. Check the following:
The power switch on the mains supply outlet is not switched on. Check
that the switch is in the ON position.
The mains power outlet is not functioning. Test the mains power outlet
with some other equipment you know works.
If the problem persists, please contact your authorised Allied Telesyn dis-
tributor or reseller immediately.
System LED stays on
If the System LED stays on contact your authorised Allied Telesyn distributor
or reseller immediately.
LAN Link LED does not light
If the LAN Link LED corresponding to the port to which your PC is connected
does not light, there is be no Ethernet communication between them. Your PC
should be connected to one of the four LAN ports with an Ethernet UTP direct
cable.
Make sure the Ethernet card on your PC is connected to one of the four
LAN ports on the back of the router.
If your PC is connected to LAN port 4 with an Ethernet UTP direct cable,
make sure the PC/Hub switch is in the PC position (out). (If this connec-
tion is made with an Ethernet crossover cable instead of a direct cable, put
this switch in the reverse Hub position.) You can reverse this switch by
pressing with a narrow implement.
Check that you have the correct Ethernet UTP cable.
If the problem persists, contact your authorised Allied Telesyn distributor
or reseller.
If the router is connected to a hub to extend the LAN, LAN port 4 should be
connected to the hub with a UTP direct cable.
Make sure the hub is connected to LAN port 4 with a UTP direct cable.
Check that the PC/Hub switch is in the Hub position (in). (If this connec-
tion is made with a crossover cable instead of a direct cable, put this switch
in the reverse PC position.)
Check that you have the correct Ethernet UTP cable, and that it is function-
ing. Try with another cable if you have one.
If the problem persists, contact your authorised Allied Telesyn distributor
or reseller.
