When setting the DIP switches, consider the following:
❑
Setting the Auto Neg DIP switch for the twisted pair port to ON or
OFF enables or disables auto-negotiation for the port. If you disable
auto-negotiation, be sure to set the DIP switches for the port’s speed
and duplex mode to match the speed and duplex mode of the end-node.
❑
For the fiber optic port, set the port’s duplex mode using the
appropriate Duplex Mode DIP switch. This setting must match the
duplex mode capability of the end-node to be connected to the port.
4. If you are installing the bridging converter in an AT-MCR12 chassis,
download the AT-MCR12 Chassis Installation Guide from our web site for
instructions on how to install the bridging converter, then proceed to
