Blocking Standby SPE Maintenance
Activities for System Testing
Sometimes it is necessary to block Standby SPE maintenance activities so that
system technician commands that test Standby SPE components can be
conducted without being blocked with the G3MT terminal message line “Standby
SPE busy with another task; for information use ‘status system’.” To block
Standby SPE maintenance activities, perform the steps listed below.
!
WARNING:
The following procedure involves throwing the SPE Select Switches to
hard-select the current Active SPE. After completing the circuit pack
replacement procedure, verify that the SPE Select Switches have been
returned to the AUTO position both by noting their position and by noting
that the SPE Select Switch LEDs on the TN772 Duplication Interface circuit
packs are not on.
1. Throw the SPE Select Switches (on the TN772 Duplication Interface circuit
packs) to force selection of the current Active SPE. If SPE-B is currently
the Active SPE, throw both SPE Select Switches to the right. If SPE-A is
currently the Active SPE, throw both SPE Select Switches to the left.
2. Issue the status system 1st-cabinet command from the G3MT terminal.
The status system form indicates the presence of MAJOR and MINOR
alarms on both SPEs. If SPE alarm counts are displayed, run component
tests to resolve these alarms. Allowed tests include test spe-standby, test
duplication-interface, and test shadow-link. Use the next step if the
allowed test commands are not accepted, otherwise skip the next step.
!
CAUTION:
If the Duplication Interface circuit pack is being tested, Test #278
fails because the SPE Select Switches are thrown.
3. Issue the busyout spe-standby command followed by the release
spe-standby command to force the Standby SPE into a mode to accept
the test commands attempted in the previous step. Wait 5 minutes for the
Standby SPE to initialize and issue the status system 1st-cabinet
command. If the Standby SPE failed to initialize if the Standby SPE Mode
is down. If the Standby SPE Mode is maint/init or maint/entering, execute
the busyout spe-standby and release spe-standby command up to 2 more
times. If this step does not succeed, try this procedure again.
4. Move each SPE Select Switch back to the AUTO position.
!
WARNING:
Move only one SPE Select Switch at a time. DO NOT move both
switches at the same time.
