Reconfiguring the System
Over time, a Metasys Network that uses
JC-MER-CXB device
s
may
have to be reconfigured to account for additions and changes to
the
system. The reconfigurations that a system may undergo can be
classified as:
•
adding a new NCM or
PMI/OWS
•
moving an NCM or
PMI/OWS
•
adding a new Metasys
ARCNET
subnet
•
changing the Ethernet network
•
changing the layout of the N1 network
This section describes the steps necessary to perform each of these
different types of reconfigurations.
Adding a New NCM or P MI/OWS to an Existing Subnet
Adding a new NCM or
PMI/OWS
to Metasys does not require any
changes to the
JC-MER-CXB
hardware or software. An NCM101/401
that is added to a
JC-MER-CXB
system must be Revision K or later.
All NCM200s and NCM300s are compatible with the
JC-MER-CXB
.
To add a new NCM or
PMI/OWS
to an existing subnet:
1. Determine the correct subnet and node address for the new
NCM
PMI/OWS
. The subnet address must match the subnet address
for the ARCNET segment to which the NCM or
PMI/OWS
connects. T
he node address must be unique. You cannot duplicate
any node address, even if the two devices reside on different subnets.
2. If the device is an NCM, determine the correct subnet and node
address for its archive device.
3. Set the
device
subnet and node address 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
W
NCSETUP to set the subnet and node
addresses. When using
W
NCSETUP, don’t forget to specify
the correct subnet and node address for the archive device.
