DSL-2730E User Manual1IntroductionThe DSL-2730E supports multiple line modes. With four 10/100 base-T Ethernetinterfaces at the user end, the device provides high-speed ADSL broadbandconnection to the Internet or Intranet for high-end users like net bars and officeusers. It provides high performance access to the Internet with a downstreamrate of 24 Mbps and an upstream rate of 1 Mbps. It supports IPV6.The device supports WLAN access, such as WLAN AP or WLAN device, to theInternet. It complies with specifications of IEEE 802.11, 802.11b/g/n, WEP, WPA,and WPA2 security. The WLAN of the device supports 1T1R.1.1 Packing List 1 x DSL-2730E 1 x external splitter 1 x power adapter 1 x telephone cables (RJ-11) 1 x Ethernet cable (RJ-45) 1 x QIG1.2 Safety PrecautionsTake the following instructions to prevent the device from risks and damagecaused by fire or electric power: Use the type of power marked in the volume label. Use the power adapter in the product package. Pay attention to the power load of the outlet or prolonged lines. Anoverburden power outlet or damaged lines or plugs may cause electricshock or fire accidents. Check the power cords regularly. If you find anydamage, replace it at once. Proper space left for heat dissipation is necessary to avoid damagecaused by overheating to the device. The long and thin holes on the deviceare designed for heat dissipation to ensure that the device works normally.Do not cover these heat dissipation holes.1
