Reconfiguring The System; Adding A New Ncm Or Pmi/Ows To An Existing Subnet - Contemporary Controls Metasys JC-MER-CXB User Manual

Reconfiguring the System

Over time, a Metasys Network that uses JC-MER-CXB devices 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 PMI/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. The 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 WNCSETUP to set the subnet and node
•
addresses. When using WNCSETUP, don't forget to specify
the correct subnet and node address for the archive device.
