PDATA-PT (Packet Data Line Port)
Locating MOs when Data Application Link Fails
This sequence of steps should be used if the application is experiencing problems
and the health of the ports is unknown.
1. Using column three of the commands table below, find the command to
display the status of the application link. Enter the command to confirm the
health of the link. If the command requires a data-module extension, enter
list data-module to determine the extension.
2. If column two of the table below shows there is a link MO for the
application, enter display alarms and display errors. If there are alarms
or errors against the MO, follow the repair procedures for that MO.
3. Using column 4 of the table below, find the command to display the
extension of the application link. Enter the command and record the
extension.
4. Enter status data-module ext for the extension found in the previous step.
Record any connected ports.
5. If there are connected ports enter display port UUCSSpp and record the
extension for each port. The equipment type displayed should be SYSTEM
PORT DATA MODULE. Run status data-module ext for the connected
port. Record the associated PDATA port.
6. If there are no connected ports, follow the steps in
Port Pool''
7. For each port, application extension, and connected Data Line and PDATA
ports, check the alarm and error logs for entries against these ports.
Follow the repair procedures for each port with problems.
8. Enter list sys-link and look for a SAP-type link with a port location that
matches the PDATA port. Check the alarm and error logs for entries
against the SYS-LINK. Follow repair procedures for SYS-LINK problems.
Locating MOs when only Problem Port is Known
A system port problem may originate in any of the following three components.
You may not know at first which is causing the problem.
The application port
The PDATA port
The Data Line port
1. Enter display port UUCSSpp to find out what kind of port this is. Record
the extension and the identification field. The identification field likely
indicates a system-port or another type of data-module.
