• For an NCM, use NCSETUP to set the subnet and node

addresses. Once the subnet address for an NCM is changed,

you will not be able to communicate with the NCM over the

N1 network until it is physically attached to its new subnet.

When using NCSETUP, don’t forget to specify the correct

subnet and node address for the archive device.

4. Change the subnet and node addresses for the device in the

Metasys database. This is done by updating the DDL global file.

5. Physically attach the device to its new ARCNET segment.

6. You do not need to make any changes to the Metasys Ethernet

Router or the ROUTER.CFG file. The router automatically

routes messages correctly based on the new subnet address for

the device.

Adding a New Metasys Subnet

When a new device cannot be attached to one of the existing

ARCNET segments, a new subnet and a new Metasys Ethernet

Router must be added. To add a new subnet, do the following:

1. Determine a location for the new Metasys Ethernet Router. The

router must have access to electrical power, a connection to the

customer’s Ethernet network, and a connection to the new

ARCNET segment.

2. Select a new subnet address for the new ARCNET segment.

The subnet address must be unique (not previously used for a

different ARCNET segment).

3. Obtain Internet address information for the new Metasys

Ethernet Router from the customer’s communications/computer

support staff. The information should include an IP address for

the Metasys Ethernet Router, the subnet mask that is used, and

an IP address for the customer’s existing LAN Router (if the

customer’s Ethernet network uses LAN Routers).

4. Obtain another Communication Processor with Metasys

Ethernet Router program installed into two spare slots of a

MOD HUB powered card cage.

5. Install the new Metasys Ethernet Router and attach the new

router to the Ethernet network and to the ARCNET network.
