Reliability Systems: A Maintenance Aid
Each Duplication Interface circuit pack has another red LED associated
with the SPE Select Switch. The purpose of the red switch LED is to serve
as a reminder that an SPE is being forced to be the Active SPE and,
therefore, the system is not duplicated. Both SPE Select Switch LEDs (one
on each Duplication Interface circuit pack) are on when an SPE is being
forced to be the Active SPE by the consistent positions of the two SPE
Select Switches. Both LEDs are extinguished when the SPE Select Switch
positions are inconsistent or when both SPE Select Switches are in the
position. In the latter two cases, the Active SPE is automatically selected
by the system software.
