alarms, minor alarms and warning alarms have no effect on memory shadowing
or on the SOH of the standby SPE.
When handshake communication is down, but the standby SPE is not in
SPE-down mode (SOH is not
nonfunctional
), autonomous testing of standby SPE
components by the SMM occurs on the standby SPE. If a component fails a test
while handshake is down,
its red LED is lit and the standby SOH is lowered to
partially-functional.
A standby SPE component is considered to be testable if it can be tested with
the usual maintenance commands from a management terminal connected to an
ACTIVE connector on the SPE. In this condition, full maintenance software for it is
running in the active SPE and the error/alarm data for it is up to date. Table 1-6
gives testability requirements for the various SPE components.
