Setting the IP Address,
Subnet Mask, and Gateway
Address
By default, the adapter is configured so that you set its IP address, subnet mask,
and gateway address using a BOOTP/DHCP server. To use adapter parameters
instead, you must disable BOOTP/DHCP and then set the associated adapter
parameters.
The IP address can be set using the rotary switches on the adapter to an address
from 1…254 that will be used as the lower byte of the IP address 192.168.1.xxx.
The Subnet mask will be set to 255.255.255.0.
If the rotary switches are set to any invalid address (0 or >254), the address
programmed in the adapter's internal data base will be used.
Disable the BOOTP Feature
1. Set the value of Parameter 03 - [BOOTP/DHCP] to ‘0’ (Disabled).
Note: The internal port used by the adapter is different for different
products. The examples here show port 5, used by the SMC Flex and drive
products. The SMC-50 uses port 4.
2. Reset the adapter; see Resetting the Adapter on page 43 .
After disabling the BOOTP/DHCP feature, you can then configure the
IP address, subnet mask, and gateway address using adapter parameters.
Set an IP Address Using Parameters
1. Verify that Parameter 03 - [BOOTP/DHCP] is set to ‘0’ (Disabled).
