– IP Type: With this setting you determine whether you want to assign the IP
Address, the Subnet Mask, the Standard Gateway as well as the Primary
and Secondary DNS address as xed values or whether these should be
dynamically assigned via a DHCP server.
Note: After 5 unsuccessful attempts at obtaining an address with DHCP
the system will revert to xed assignment
Factory setting: DHCP
Options: DHCP (dynamic assignment)
Fixed (xed assignment)
– IP Address: This eld shows the actual IP address of the device assigned
manually or assigned by a DHCP server.
If the parameter "IP Type" is set to "Fix", the IP address of the device can
be set via this eld. If the parameter "IP type" is set to "DHCP", the IP
address of the device is assigned by a DHCP server.
– Subnet Mask: This eld shows the actual subnet mask of the IP network
assigned manually or assigned by a DHCP server.
If the parameter "IP Type" is set to "Fix", the subnet mask can be set via
this eld. If the parameter "IP type" is set to "DHCP", the subnet mask is
assigned by a DHCP server.
– Default Gateway: This eld shows the actual IP address of the default
gateway assigned manually or assigned by a DHCP server.
If the parameter "IP Type" is set to "Fix", the IP address of the default gate-
way can be set via this eld. If the parameter "IP type" is set to "DHCP",
the IP address of the default gateway is assigned by a DHCP server.
