Troubleshooting

This sections contains troubleshooting recommendations should you encounter
any problems with the unit.
If the Power LED does not light up after connecting the AC power cord, do the
following:
Make sure that the power cord is securely connected to the front of the
AT-EX1001SC/GM1 Multimode Extender and that the other end is
securely connected to a power outlet.
Try using another power cord to see if power is supplied to the unit.
Check that the power outlet has power by connecting another device
to it.
If the PLL Lock and SC LEDs of Port 1 do not illuminate after connecting both
AT-EX1001SC/GM1 Multimode Extenders, do the following:
Make sure that the power cords of both units are securely connected
to their power outlets and that power is being fed into the units.
Check the connections between units. The cable attached to the TX
port of one unit should connect to the RX port of the other unit.
Make sure that the entire network is functioning properly in case the
problem might lie beyond the unit.
If after connecting one of the units to the host device the PLL Lock and SC
LEDs of Port 2 fail to light up, do the following:
Make sure that both the host device and the AT-EX1001SC/GM1
Multimode Extender are powered up and functioning properly.
Check the connections between the AT-EX1001SC/GM1 Multimode
Extender and the host device. The cable attached to the TX port on
AT-EX1001SC/GM1 Multimode Extender should connect to the RX
port of the host. Likewise, the RX port of the unit should connect to the
TX port of the host device.
Check that the entire network is functioning properly in case the
problem might lie beyond the AT-EX1001SC/GM1 Multimode
Extender.
