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 unit
s 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
device
s 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.
