Configuring the DIP Switches
To configure the DIP switches on the back panel, refer to Table 11.
Here are several guidelines to setting the DIP switches:
❒
The twisted pair port has to be set to Auto-Negotiation to operate at
1000 Mbps.
❒
Setting DIP switch 1 to On to activate Auto-Negotiation disables DIP
switches 2 and 3.
❒
To manually configure the speed and duplex mode of the twisted pair
port with DIP switches 2 and 3, you have to disable Auto-Negotiation
with DIP switch 1.
❒
The setting of DIP switch 4 must match the type of SFP module the
unit contains. If this DIP switch is set incorrectly. the port on the SFP
module will not establish a link with the remote network device.
❒
You can change the DIP switches even when the unit is powered on. A
change to a DIP switch setting is immediately implemented by the unit.
❒
The wiring configuration of the twisted pair port is always set with
Auto-MDI/MDI-X, even when Auto-Negotiation is disabled. You cannot
manually set the port’s wiring configuration.
