Indicates that power has not been applied or there is a hardware
failure. Contact Technical Support.
Isolate the DeviceMaster EIP-MOD from the network. Connect the
device directly to the NIC in the host system (see Page 155).
The default IP address is often not accessible due to the subnet
masking from another network unless 192.168 is used in the network.
In most cases, it will be necessary to program in an address that
conforms to your network.
Invalid IP information may also cause the switch or router to check for
a gateway address. Lack of a gateway address is a common cause.
