Also, make certain that the other network
device is powered on and operating
correctly.
•
Verify that the transmit port on a NetIron
MLX Series router is connected to the
receive port on the other network device,
and that the receive port on the NetIron
MLX Series router is connected to the
transmit port on the other network device.
If you are not certain, remove the two
cable connectors from the port connector
and reinsert them in the port connector,
reversing their order.
•
Dust may have accumulated in the cable
connector or port connector. For
information about cleaning the
connectors, see “Cleaning Fiber-Optic
Modules” on page 4-6.

If the other actions don’t resolve the
problem, try using a different port or a
different cable.
