Connecting PC Connect the provided Ethernet cable to the LAN port of the Corecess 3121 and then connect the other end of the cable to Ethernet port on the NIC installed to your PC. Note: If you are connecting a LAN to the Corecess 3121, you must use a “crossover” Ethernet cable (not provided) to attach a regular hub or switch port. The crossover cable is wired differently than the cable you would use to connect to a hub. When you compare the colored wires on each end of a straight-through cable, they will be in the same sequence; on crossover cables, they will not. Contact your ISP for assistance. Connecting Console Terminal Caution: General users need not to connect a console terminal. It is only for the ADSL Service Provider. Connect a console cable to the CONSOL port of the Corecess 3121 and then connect the other end of the cable to the terminal or a PC. noPHONE LINECONSOL5V DCOFF ONLAN

Corecess 3121 Installation Guide 14 Troubleshooting If you cannot connect to ADSL network, please check the status of the LEDs on the front panel, and then ensure the following: 1. Check the LAN LED If the LAN LED goes off, ensure that the Ethernet cable is firmly connected both to the LAN port on the Corecess 3121 and Ethernet port on the NIC installed to your PC. 2. Check the DSL LED If the DSL LED blinks continuously and never stays solid on, ensure that the DSL cable is firmly connected to the LINE port on the Corecess 3121. If the DSL LED still blinks, contact your ADSL service provider. If the DSL LED goes off, turn off the power of the Corecess 3121 by pressing the power switch and turn on the power again. If DSL LED still blinks, contact your vendor. 3. Check your PC’s IP address If all LEDs operate normally and cables are firmly connected to the ports, ensure that your PC’s IP address is properly assigned. Otherwise, assign a new IP address according to your operating system. Windows 95/98/ME n Click the Start button and select Run. o Input winipcfg and press the [Enter] key.
