Functional description and configuration using Web Based Management
7.3 Assignment of an IP address
DHCP (factory setting)
When the devices ship and after resetting to factory defaults, DHCP is active. If a DHCP server
is available in the local area network, and this responds to the DHCP request of the IE switch,
the IP address, subnet mask and gateway are assigned automatically when the module first
starts up.
