Maintenance Object Repair Procedures
555-233-123 10-1604 Issue 4 May 2002
System Printer Link Maintenance does not cover the elements comprising the
SYS-PRNT physical link; that is, the external SYS-PRNT output device, the EIA
port on the Processor circuit pack, the Data Module (PDM/MPDM/DTDM) and the
Digital Line of TN754 or TN754B Digital Line circuit pack, the ADU and the Data
Line of TN726 Data Line circuit pack, and the data channels on the TN777
Network Control circuit pack. If System Printer Link Maintenance cannot restore
the System Printer Link, the maintenance tests of these individual components of
the System Printer Link must be executed to diagnose faults.
Procedures for Restoring the System Printer Link
The following procedures should be followed to restore the System Printer Link:
1. Determine the status of the System Printer Link via the status sp-link
command. Verify that the System Printer Link is not busied out for
maintenance. On the System Printer Link Status Form, this is indicated by
a “no” in the “Maintenance Busy?” field. If the System Printer Link has been
busied out, issue the release sp-link command. If the link is “down,”
proceed to Step 2.
2. Issue the display system feature command to determine the destination
of the System Printer Link.
If the destination is an extension number, enter the status data-module
<extension> command and verify that the data extension is in-service/idle.
If the data extension is NOT available, refer to the “Port/Channel Number”
field on the “Data-Module Status” Form. Look for errors and/or alarms on
the circuit pack with which this extension is associated. Refer to the
appropriate MO documentation for recommended repair strategy. Continue
with Step 3.
If the destination is eia, look for PR-MAINT errors in the Hardware Error
Log. If errors are present, refer to Maintenance/Tape Processor
Maintenance documentation, and continue with Step 5.
3. Determine if a data channel on the Network Control circuit pack is
in-service/idle as follows:
a. Use the list data-module command to find out the extension
numbers of the data channels on the Network Control circuit pack.
(There is a maximum of 4. They are listed as “netcon” on the Active
SPE. Ignore the Standby data channels.)
b. Enter the status data-module <extension> command to verify that
at least one Active data channel is in-service/idle.
