3. Configure the DIP switches. Refer to Figure 3 on page 2 for the location of
the DIP switches and Table 6 for the possible settings.
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 switch in an AT-MCR12 chassis, refer to the
chassis’ installation guide for instructions on how to install the switch,
then proceed to Step 7.
