SPE-SELEC (SPE Select Switch)
The SPE Select Switch MO tracks the state of the SPE Select Switches in a High
or Critical Reliability system. The switches are located on the Duplication
Interface circuit pack and can be used to hard-select the active processor in a
High or Critical Reliability system. Each switch has three positions: SPE-A (the left
position), AUTO (the middle position), and SPE-B (the right position). To
hard-select SPE-A, both switches must be in the SPE-A position. To hard-select
SPE-B, both switches must be in the SPE-B position. Any other combination of
SPE Select Switches leaves control of the active SPE to the software. Whenever a
switch is out of the AUTO position, a Warning alarm is raised. If both switches are
out of the AUTO position for six hours, a Major alarm is raised. Duplication
Interface circuit pack B reports the state of the SPE-SELEC Switch B to
Duplication Interface circuit pack A which, in turn, reports the state of
SPE-SELEC Switch A directly to the system software.
NOTE:
Each switch is a separate MO. If both switches are out of the AUTO
position, then both switches are alarmed.
It is also possible to get an "init cause" of the SPE-SELEC Switch if SPE B is active
and power to carrier B is lost. In this case, an SPE switch to SPE A occurs, and
the "init cause" shows either "SPE-Select Switch" or "SPE-Down."
