DHCP Server
When using the DHCP feature, the IP address settings of the card (IP address, subnet mask,
and default gateway) will be assigned by a DHCP server.
However, keep in mind that the maintenance of the card is performed through a web browser
from a PC; hence you must know the IP address of the card. Therefore, it is necessary to set
up the DHCP server to assign a static IP address to the card from a pool of IP addresses that
is defined in advance. For more information about DHCP server settings, consult your network
administrator.
In addition, it is also necessary to specify the values for the parameters under "
" as they will be assigned by the DHCP server.
