DS Powerup Procedure

This topic details steps that the DS takes after the powerup. Shown on the left are status LED patterns that are displayed during each step of powerup procedure.

LED_powerupStep 1: powerup and initialization. The DS boots up and prepares for operation. At this time all internal settings of the DS are verified and the hardware is checked.
LED_error_modeIf at least one of the settings is found to be invalid the DS enters the error mode. In this mode the DS is still accessible through the network but its functionality is limited.
LED_eth_failEthernet port malfunctions are also detected at this stage.
LED_IP_not_obtainedStep 2: IP-address configuration. When the  DHCP (DH) settingis at 0 (disabled) the DS simply uses IP-address that is set in the IP-address (IP) setting, in which case IP-address configuration is instantaneous. When DHCP setting is at 1 (enabled) the DS attempts to obtain its IP-address using DHCP protocol. The DS stays on this step of powerup procedure until the IP-address is properly configured.
LED_IP_not_obtained[V3.54+]: Step 3 (optional): PPPoE link establishment. If  PPPoE Mode (PP) settingis at 2 (on powerup) the DS attempts to establish a PPPoE link. The DS will stay on this step of powerup procedure until the PPPoE link is successfully established.
LED_pppoe_failedPPPoE login failure. If PPPoE authentication fails (because the data in the PPPoE Login Name (PL) or  PPPoE Login Password (PD)settings is incorrect or because Access Concentrator doesn't support PAP authentication protocol) the DS indefinitely continues attempts to establish the link.
<Several different patterns>Step 4 (optional): registration at dDNS. If  dDNS Service Registration (DD) settingis at 1 (enabled) the DS attempts to connect to the dDNS Service of the Link Server. Destination IP-address and port are specified by the dDNS Service IP-address (LI) and dDNS Service Port (LP) settings. At this point the DS goes through several different steps- just like for a normal outgoing TCP data connection.
LED_tls_faileddDNS login failure. dDNS login may fail (because the data in the Owner Name (ON), Device Name (DN), or  Password (PW)settings is incorrect or for some other reason). When LS Auto-registration (AR) setting is at 1 (enabled) and the DS is informed that it is not currently registered on this Link Server it will attempt to register.
LED_conn_closedProcedure completed: idle state. At this point the DS is fully configured and operational. If Routing Mode (RM) setting is 1 (server/client) or 2 (client only) AND Connection Mode (CM) setting is 0 (immediately) the DS proceeds straight to attempting to establish an outgoing data connection.
