5.
Physically attach the new NCM or
PCI/OWS
to the ARCNET
segment t
hat you have selected.
6.
You do not need to make any changes to the
JC-
ME
R-CXB. The
router
automatically
routes messages
correctly using subnet
address for
the new
device.
Moving an Existing NCM or
PCI/OWS
or NIE
to a Different
ARCNET
Subnet
You may want to change the ARCNET segment to which an NCM or
PCI/OWS
is attached. This may be required because an NCM or PC
I/
OWS i
s
moved to a new location or because the ARCNET cable layout
has
been changed.
Moving an NCM or
PCI/OWS
to a different subnet
does not
require any changes to the
JC-MER-CXB
software.
To move
a device to a different subnet, follow these steps:
1.
Determine the new subnet and node address for the NCM or
the
PCI/OWS. Y
ou will probably use the same node address for the
device, but
if you decide to change the node address, it must be
unique.
You cannot duplicate any node addresses, even if the two
devices reside on different subnets. The device’s subnet address
will have to change to match the subnet address for the
ARCNET segment to which the device will be moved.
2.
If the device is an NCM, you may want to change its archive
device. If you decide to change the archive device for the NCM,
determine the subnet and node address for the new archive
device.
3.
Change the subnet and node address for the device as you
normally do.
•
For a
PCI/OWS
, set the node address using the switches on
the
ARCNET card (note: PS/2 system cards do not have
switches, so PS/2 users can ignore this) and specify the
subnet and node addresses in the DDL network
configuration file.
•
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.
Add the device to the system database, either by updating the
DDL global file or by using a device definition window.
