Displays the failure reason for a SWACT denial or failure performed
during a manual REx at the MAP terminal as REx failed. Use the
command string TST REx QUERY for the posted XPM to obtain the
reason for the failure. The system generates a PM600 log report that
details the REx failure reason.
SREX scheduler feature AF3771
Feature AF3771, System REx Controller: XPM Maintenance, provides the
SuperNode switch with an SREX controller. The SREX controller
coordinates the system REx tests under a common REx scheduler. This
feature allows you to schedule SMS REx tests when other REx tests are in
progress. The SREX controller can REx test the whole switch more easily
and in less time. The switch includes peripherals like the SMS. Feature
AF3771 allow you to find and resolve REx test failures faster, which reduces
outages in the field. The SREX controller allows the operating company
personnel to:
change the test order of peripherals
coordinate between manual and system initiated REx tests
receive alarms for SMS not REx tested in a time limit set in table
REXSCHED
The SREX scheduler allows you to enter the CI level command REXTEST
and the following parameters:
The SUSPEND parameter suspends REx tests for one maintenance
window. A maintenance window is the time between the REx START
and STOP time entered in table OFCVAR under parameter
NODEREXCONTROL.
The RESUME parameter resumes REx tests suspended with the
SUSPEND parameter.
The QUERY parameter displays the state of the REx test, active or
suspended.
The HELP parameter displays a short description of the REx test.
Note: A maximum of 10 concurrent XPM REx tests of each type can
run at the same time.
The REx test order for feature AF3771 appears in the following list:
critical nodes, like CM and MS
the number of days between the last system or manual REx test and now
the internal PM (SMS) number order
