7.1.2 DHCP (Dynamic Host Configuration Protocol) ServerTo establish communication over a VoIP network, IP addresses must be assigned to IP telephones and thePBX to identify their locations on the network. While these addresses can be assigned manually, it is alsopossible to use a DHCP server to automatically assign IP address information. The KX-NS1000 has a DHCPServer feature. Therefore, the PBX can act as a DHCP server or DHCP client depending on its settings. Whenthe PBX’s DHCP Server feature is enabled, it allows you to centrally manage and automate the assignmentof IP addresses with Web Maintenance Console. For details, refer to " DHCP Server" in the PC ProgrammingManual.Assign IP addressinformation to an IPtelephoneWhen the mother board isconnected to the network When an IP telephone isconnected to the networkRequest IP addressinformation1Assign IP addressinformation to theDSP cards2Request IP addressinformation34PBX(DHCP Serverfeature enabled)DSP CardIP TelephoneNote• The DHCP Server feature is disabled by default. To enable the feature, refer to "5.4.2 Enabling theDHCP Server Feature".• An IP telephone and the mother board/DSP cards cannot request IP addresses from a DHCP serveron another LAN (connected through an IP network). They can only receive IP addresses from a DHCPserver on the same LAN. Therefore, when IP telephones are located on several LANs, a DHCP serveris required on each LAN. If a DHCP server is not present on the LAN, IP addresses for IP telephonesand the mother board/DSP cards on that LAN must be assigned manually.• When the PBX has been set to act as a DHCP client, use an external DHCP server to assign IP addressinformation automatically.• When the KX-NS1000 is set as the DHCP client and cannot receive appropriate IP addressinginformation from an external DHCP server, the PBX keeps using the previous effective IP addressinginformation and checks whether any overlapping of IP addresses exists. If the IP address of the PBXoverlaps with another IP address, the PBX displays a warning to encourage changing the IP addressof the PBX.Installation Manual 2197.1.2 DHCP (Dynamic Host Configuration Protocol) Server
