SYS-PRNT (System Printer)
S8700 | 8710 / S8500
The Report Scheduler feature provides the capability to schedule printing of output screen
selected administration commands on an asynchronous System Printer (SYS-PRNT) or a
Personal Computer (PC). The System Printer device connects to the system via a data module
(PDM, MPDM, DTDM) connected to a port on a TN754 Digital Line circuit pack which is
administered as a data extension. A System Printer device can also be connected through an
ADU to a port on TN726B Data Line circuit pack. The System Printer link to the processor is via
a C-LAN board. For information about C-LAN connectivity, see CLAN-BD (Control LAN Circuit
Pack) on page 789.
System Printer Link Maintenance provides a strategy for maintaining the link between the
system and an external SYS-PRNT output device. The strategy includes a set of tests for
detection of errors during normal operation, troubleshooting actions, and alarms for serious
problems. System Printer Link Maintenance uses a try-and-wait mechanism for maintaining the
SYS-PRNT link. A minor alarm is raised when the link set-up fails. A warning alarm is raised
when the server has been busied out. Up to two link retry attempts are made. After the second
attempt, set-up attempts are only made by the application software. (The 15-minute timer fires
and jobs are printed unless an immediate job was entered.) After two unsuccessful attempts to
establish the link, a MINOR alarm is raised. If the System Printer Link is torn down due to an
error, System Printer Link Maintenance will raise a MINOR alarm but will not attempt to bring up
the System Printer Link.
System Printer Link Maintenance does not cover the elements comprising the SYS-PRNT
physical link: the external SYS-PRNT output device, the Data Module (PDM/MPDM/DTDM) and
TN754 Digital Line, or the ADU and TN726B Data Line. 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
1. Use status sp-link and verify that the Maintenance Busy field is n, which shows that
the System Printer Link is not busied out for maintenance. If the System Printer Link has
been busied out, use release sp-link. If the link is down, proceed to Step 2.
2. Use display system-parameters features to determine the location of the System
Printer Link.
Use status data-module extension and verify that the data extension is in-service/
idle. If the data extension is not available, refer to the Port field. Look for errors and/or
alarms on the circuit pack with which this extension is associated. Follow repair instructions
for the appropriate MO. Continue with Step 3.
