Rear Panel DIP Switches Configuration
Before the AT-GS2002/SP Media Converter is installed, the rear panel
DIP switches must be configured for the two Ethernet ports. The DIP
switch are numbered 1 - 4 and each one controls a specific function for a
specific port. The port numbers assigned to each DIP switch are clearly
marked the table on the rear panel. The specific switch functions are given
in Table 7 for the possible settings.
Note
The DIP switch location is shown in Figure 2 on page 19. Port 1
(SFP port) and Port 2 (twisted-pair port) are shown in Figure 1 on
page 19.
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 device connected to the converter’s copper
port.

If you enable Auto-Negotiation, be sure that the end-node device is
also configured for Auto-Negotiation.
