Description:
This document describes the IP address and authentication data required to access LANCOM devices.


IP address in factory state:
1) LANCOM routers and access points:
  • If an unconfigured router or access point is connected to a network with a DHCP server, the device will obtain an IP address from the DHCP server.
  • If an unconfigured router or access point is connected to a network without a DHCP server, the device analyses the broadcasts to detect the network. The device uses the subnet mask 255.255.255.0 and sets its number on this network to 254. Please also see the following article.

    Example:
    A broadcast is received from the IP address 192.168.1.15. The device in this example sets the IP address to 192.168.1.254.
  • If the network has neither a DHCP server nor any other network participants, the device sets its own address to the default 172.23.56.254.
If this IP address is already assigned, this will result in an IP address conflict and lead to communication problems!


2) LANCOM switches:
  • If an unconfigured switch is connected to a network with a DHCP server, the device will obtain an IP address from the DHCP server.
  • If the switch is connected to a network without a DHCP server, the device sets its own address to the default 172.23.56.250.
If this IP address is already assigned, this will result in an IP address conflict and lead to communication problems!

3) Authentication data in the factory state:
3.1) LANCOM routers and access points:
Administrator: root
Password: There is no password set.

If no administrator is specified, the device implicitly uses the user root. If this user is to be used, the field can be left empty.

3.2) LANCOM switches GS-23xx series:
Username: admin
Password: admin


3.3) LANCOM switches GS-3xxx series:
Username: admin
Password: There is no password set.

3.4) LANCOM switches XS series:
Username: admin
Password: There is no password set.
