Testing the System Port Pool
This section describes a method for isolating a bad system port when its location
is not known. A pool of system ports is used to service the set of application
features listed above. The system supports up to 10 system ports. Since each
Data Line Circuit pack provides 8 ports and each PDATA provides 12 ports, 2
Data Line Circuit packs and one PDATA Circuit pack are required if all 10 system
ports are to be administered. If a link failed due to a faulty system port and that
port is not currently connected to the feature, you will need to test the entire pool
to isolate the bad system port. Follow these steps to isolate a bad port or
exonerate the pool of system ports.
1. Enter list data-module and record the extension for each system port.
Note: list data-module name option can be used to match on the name of
the system ports if they are all named similarly.
2. For each system-port enter display data-module ext to find the Data Line
(DAT-LINE) and PDATA ports administered. Each system port has a single
extension that applies to both the Data Line and PDATA port. For historical
reasons the PDATA is considered the associated port.
3. Check each port for alarms and errors using display alarms and display
errors.
4. Check for SYS-LINK error or alarms for SAP-type links using Display
alarms and errors.
5. Follow the repair procedures for any ports with errors.
Identifying Components of an Application Link
Use this procedure to locate the MOs that make up a given application link. You
can then follow the repair procedures for each MO. In the following steps, locate
every MO in a link before testing any ports.
Problems with the application adjunct links are reported in two ways:
The data application experiences problems.
Errors or alarms are logged against a port or extension.
