must be manually set to FDX port mode to ensure that an FDX
connection can be established.
Note that if both the RI and RO of an attached device are

Troubleshooting
•
If you are installing the interface module and the LEDs do
not come on when the base switch is powered on, verify
that the interface module is properly seated in the slot.
•
During diagnostics, the interface module DIAG LED is
on. If the ERR LED is on at any time, it indicates that the
interface module is defective and needs to be serviced.
•
Troubleshoot the interface module ports just like the base
switch ports. Refer to the base switch documentation for
troubleshooting hints.
•
If you have been unable to get the interface module INS
LED to turn on after connecting a interface module port
to another device, check that you are using the correct
cable type.
Important: Check that TX on the interface module is
connected to RX on the remote device, and that RX is
connected to TX on the remote device.
