release spe-standby causes the following:
■The standby SPE’s SOH returns to the appropriate level based on its
component alarms.
■After verifications, software turns on shad owing and refreshes the
standby’s memory.
Busyout is used to disco urage the likelihood of interchang e and prevent side
effects of memory shadowing . For example:
■When it is necessary to run the long dem and test sequence for the
duplication-interfac e hardware or to reset the standb y SPE’s
Packet-interface circuit packs
■To allow destructive testing of components relevant to shadowing
(packet-interface, mem ory, or duplication interfac e packs).
When the standby SPE is busied out, handshake communic ation is maintained if
possible. The standby SPE can be b usied-out at any time the G3-MT interface is
available, including when the system is initializing or when the ac tive SPE is
lock ed. B usyou t app lie s to on ly one inst ance of the SPEs. If SPE B is bu sied out
and a n SPE inte rcha nge o ccu rs A- carr ier SPE is not b usied out.
When releasing a standby SPE from the busyout state, make sure that the
standby SPE is brought fully bac k to service. Wait until the standby is refreshed
and its SOH returns to level
functional
to make sure repair actions did not disable
the standby SPE.
Initialization: Bringing the Standby SPE Up
When th e stan dby SPE has b een o ut of s ervic e or i s firs t co ming up, SPE
software executes the following step s:
1. Establishes handshake communic ation
2. Raises the standby SPE’s SOH to
not refreshed
if it has no critical
component alarms, or
partially functional
if it does have critic al component
alarms
3. Tests for component mismatch (test number 920)
4. Turns on memory shadowing
5. Refreshes standby memory
6. If t here a re no c riti cal- comp onen t maj or ala rms, r aise s the s tand by SPE’s
SOH to
functional
This normally takes about 5 minutes. Should a step of this initialization sequenc e
fail, the step is retried until it suc ceeds. The failed cond ition is alarmed so that it
can be diag nosed and correcte d.
