Changing The Ethernet Network; Changing The Layout Of The Metasys Network - Contemporary Controls Metasys JC-MER-CXB User Manual

Changing the Ethernet Network

Occasionally, the customer's communications/computer staff may
decide to rearrange their Ethernet network. Normally this will not
impact the operation of the JC-MER-CXB, except that it may result
in a temporary loss of communications with one or more of the
routers. Should this happen, each NCMs and PCI/OWS on those
subnets will go offline. If the customer decides to change the
configuration of their Ethernet network, you may have to change the
IP address information stored in each router. To do this, you will
have to change the configuration for each router.
If the IP address for the JC-MER-CXB was modified, you must
update the configuration screen. Change the IP address as needed.
Then use the download program to update all other routers.

Changing the Layout of the Metasys Network

In some situations you may want to reorganize the Metasys Network.
This may involve joining two existing ARCNET subnets into a
single subnet, splitting an existing subnet into two subnets, or
adding new subnets. If you are performing a major reconfiguration
of the network, follow these steps:
1. Determine the new network layout for Metasys. The new
network layout should show a number of ARCNET subnets that
are connected using JC-MER-CXB units and the customer's
Ethernet network. Assign a unique subnet number to each
ARCNET segment.
2. Using the new network layout, determine where the JC-MER-CXB
devices will be located. For each router, determine if it is an
existing router or a new router. If you will be installing new
routers, you will have to obtain them.
3. Fill out a set of JC-MER-CXB planning forms for the new
network layout. You should have filled out a set of forms when
the routers were first installed. The JC-MER-CXB Planning
Form B will be used to configure each of the JC-MER-CXB
units. If you will be installing new routers, follow the procedures
beginning on page 13.
