6Determine if you want the MDI/X switch “out” or “in”. The MDI/X Switch swaps the transmit (Tx) and receive (Rx) signal pairs on the Ethernet port. The MDI/X button must be pressed “in” to use the port for connection to a workstation. When the MDI/X button is “out”, you can connect to a non-cascade port on another hub.

7Plug one end of the power adapter into a wall socket, and connect the other end of the cable to the rear of the HomeConnect ADSL Modem Ethernet.

What are the Boot Options?

The 3Com HomeConnect ADSL Modem Ethernet has a set of 4 numbered DIP (Dual Inline Package) switches that can be used to select a pre-programmed configuration. One of the pre-programmed configurations may match the settings required by your service provider. Please check with your service provider. If so, installation is as simple as setting the DIP switches and powering on the unit. If not, you can still easily configure the unit using a serial console connection.

The following DIP switch combinations are valid:
