manual abstract
2 Connect one end of the ADSL cable (RJ-11) to the connector on the rear of the HomeConnect ADSL Modem Ethernet marked ADSL and connect the other end to your ADSL wall jack (or Network Interface Device (NID)). CAUTION: The DSL line outlet uses the same type connector as a normal voice telephone line. Take care not to accidentally connect your HomeConnect ADSL Modem Ethernet to a telephone outlet, and never connect a phone to your HomeConnect ADSL Modem Ethernet. 3 Select the DIP switch mode (this selects the boot option) you want to use from the table below (Table 1.1) and flip the appropriate switches. 4 Connect the Ethernet cable to the Ethernet port on your Modem and the other end to the PC or network hub. Do not confuse this cable with the RJ-11 ADSL cable. The two RJ jacks look alike. 5 Install the ferrite clamp: Adding the ferrite clamp onto your Ethernet cable will minimize electromagnetic interference from your ADSL modem. In order to ensure compliance with EN55022 (CISPR 22) and FCC Part 15 Class B emission requirements, attach the ferrite clamp to the Ethernet cable as shown below. The clamp will be most effective when placed closest to the end of the Ethernet cable (see diagram below) which is connected to your modem. Place the open clamp around the cable portion close to the jack which will be connected to the ADSL Modem Ethernet unit. Close the clamp around the cord, making sure the two small clips are completely closed (they will be flush with the clamp body). The clamp is now properly attached to the Ethernet cable. 1-6 CHAPTER 1: INTRODUCTION TO THE HOMECONNECT ADSL MODEM ETHERNET 6 Determine 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. 7 Plug 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: Table 1-1 DIP Switch Modes DIP Switch Mode 1 2 3 4 VPI/VCI off off off off Unconfigured Mode (CLI configuration required) ON off off off 0/33 off ON off off 0/35 ON ON off off 8/35 off off ON off 0/38 ON off ON off 0/33-35 off ON ON off 0/33-38 all other settings Unconfigured Mode (CLI configuration required) Boot options only affect the operation of a unit which does not presently have any configuration settings (i.e., the unit is new, the Configuration Reset button has been pressed, Installation of the 3Com HomeConnect ADSL Modem Ethernet 1-7 or a ‘delete configuration’ command has been executed from the CLI). Changing Boot Options/Resetting Your Modem You may choose a different boot option after you have already selected one previously and set up your unit. To reset your unit and select a different boot option: 1 Set the appropriate DIP switch to match the configuration information provided by your service provider. 2 Unplug the power cable from your 3Com HomeConnect ADSL Modem Ethernet. 3 Press the Configuration Reset button for 5 seconds while plugging the power cable back in. Following the above steps will power on the 3Com HomeConnect ADSL Modem Ethernet with the desired boot option and erase all previous parameters. Unconfigured Mode If you have not selected one of the preconfigured boot options, the unit will power up unconfigured. To enter configuration information, you must connect a PC running terminal emulation software (e.g., Hyperterminal, available on most PCs) to the unit’s console port. Connect the 9-pin console cable from the terminal to the back of the unit. Configure your terminal with the following serial port settings: 9600-N-8-1. Refer to the Command Line Interface (CLI) Guide for details on accessing this interface. The 3Com HomeConnect ADSL Modem Ethernet bridges traffic between ATM PVCs (WAN ports). To configure a WAN port, use the following command syntax: set port
