Maintenance Commands and Trouble-Clearing Aids

busyout spe-standby
This command raises the Fault Severity Level of the Standby SPE (see reference
5) of the standby Switch Processing Element (SPE) by raising a Warning
Off-board alarm against STBY-SPE. Because a Warning Off-board STBY-SPE
alarm is defined to have the highest Fault Severity of all alarms the affect the
health of an SPE (refer to the Reset System MUS), the chance that an SPE
interchange will occur is diminished, but does not guarantee that an SPE
interchange will not occur. Once the standby SPE is busied out, an SPE
interchange occurs if the standby SPE is hard selected with the SPE Select
switches or the active SPE goes into SPE down mode. This command also stops
any activity currently executing on the standby SPE and disables memory
shadowing to the standby SPE. Periodic and scheduled testing cannot start on
the standby SPE while it is busied out. The busyout state of the standby SPE and
the STBY-SPE Warning alarm are maintained across a reset system 1 (Warm
restart) and a reset system 2 (Cold 2 restart) but are removed after all other levels
of restart.
Feature Interactions
■ When a busyout of the standby SPE is performed, the fault severity level of
the standby SPE is set to the highest possible value and memory
shadowing is turned off. This is done to reduce the probability that the
system switches to the standby SPE. However, in some cases a
“spontaneous” (hard) interchange of the SPEs may still occur.
■ This command can be used as a mechanism to turn off memory shadowing
of the standby SPE.
■ If the standby SPE is in poor health (less than optimum), memory
shadowing can not be disabled, or communication to the standby is
impossible a busyout of the standby SPE are still successful.
