Scheduled Maintenance
An automated series of maintenance tests and operations runs daily according
to the schedule and settings specified in the following fields
Table 8-1. Scheduled Maintenance Settings
Start Time
Hour and minute (24-hour notation) when daily scheduled maintenance
starts
Stop Time
The hour and minute when scheduled daily maintenance ceases. If any
daily maintenance operations are not completed by this time, the
system notes its stopped sequence location and includes those
operations during the next scheduled daily maintenance.
Daily
Maintenance
This display-only field lists the standard test series run by maintenance
software during daily maintenance.
Save
Translation
Indicates days that translation data in memory automatically saves to
the Mass Storage System disk and/or tape devices during scheduled
maintenance. The operation saves to disk, then completes a backup to
tape. Translation data saves to both SPEs, if systems have duplicated
SPEs. (daily, days of the week, or no) “No” prevents automatic saves.
Control
Channel
Interchange
Each port network has a pair of TDM busses called A and B. Each has
a set of time slots dedicated to the control channel. One bus (at a time)
carries the control channel in each PN. (daily, days of the week, or no)
“No” prevents interchanges. (no)
System Clocks
Interchange
For High and Critical Reliability systems, this option initiates a
Tone-Clock interchange in each port network possessing duplicated
Tone-Clock circuit packs. Each port network interchanges into the
standby Tone-Clock for 20 seconds and then back to the
originally-active Tone-Clock. This field indicates the days that
interchanges occur. (daily, days of the week, or no). “No” prevents
interchanges. (no)
The system performs a Tone-Clock interchange, activating the stand by
Tone-Clock. After the newly-active Tone-Clock circuit pack is tested, it
provides system clocks for its native port network. Then the system
interchanges to the originally active Tone-Clock circuit pack.
SPE
Interchange
This field indicates the days SPE interchanges execute during
scheduled maintenance, for duplicated SPE systems. (daily, days of
the week, or no). “No” prevents scheduled interchanges. (no)
