Setting IP Address related Items by DHCP Under environment with a network operating a DHCP server DHCP protocol allows the user to automatically set the IP address subnet mask gateway and name server of ezTCP Using DHCP automatic setup function requires the user to check DHCP item on ezConfig Note that the user may have to check ARP item according to the type of DHCP servers Setting IP Address related Items by PPPoE PPPoE is used in most ADSL and VDSL To use PPPoE function PPPoE function should be enabled and PPPoE ID and PPPoE password should be configured The local IP address of EZL 50L M is assigned automatically in PPPoE environment N Some ADSL or VDSL modem use DHCP Please contact your ISP Internet Service Provider 205 4 Operation Mode 4 1 Operation Mode Overview 4 1 1 Overview EZL 50L M can operate in one of two modes normal and ISP modes Normal mode is ordinary data communication mode and ISP mode is used to download EZL 50L M firmware through the ethernet TFTP 4 2 How to Initiate Each Operation Mode 4 2 1 How to Initiate Normal Mode Normal mode is a mode in which EZL 50L M performs its original functions If ISP 15 HIGH when EZL 50L M boots up EZL 50L M operates in normal mode For more information see 5 Normal Communication Mode 4 2 2 Entering ISP Mode Supply power or reset to EZL 50L M with ISP pin LOW If EZL 50L M operates as ISP Mode Status repeats HIGH LOW
