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 -
prevents automatic saves)
Control
Channel
Interchange
Each port network has a pair of TDM busses (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 - prevents interchanges). (n)
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. (n)
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. (n)
