Ethernet Switch Settings
This table describes the Ethernet switch settings.
Ethernet Switch Setting Description
To set the IP address of the linking device to the 192.168.1.xxx sub net, set the
switches to the required last three digits.
In this example, the linking device will start up with IP address: 192.168.1.123.
To set the IP address of the linking device via a BOOTP server, set the switches to
888 (factory default setting).
Power up the linking device and set the IP address by using any BOOTP server.
Once the new IP address has been set, power down the linking device, return the
switches to 000, and power up the linking device.
Normal setting after setting IP address with BOOTP.
The 000 setting disables BOOTP and holds the IP address.
The linking device can run the firmware with which it was originally shipped.
If power was cycled while upgrading the firmware, the firmware can be corrupted
and prevent the linking device from starting up.
Set the switches to 777 to set the linking device into Safe mode and upgrade the
firmware again.
