To restore handshake, proceed through the following steps.
1. Make s ure tha t the SPE i s not lo cked , and that i t has p ower. Resolve any
CARR-POW a larms on the s tand by SPE ca rrier . (If th e stan dby SO H is
partially functional or b etter, you can assume that the standb y SPE has
power.)
2. Busyout the standby SPE and run test dup long. Some DUP-CHL tests
may abort due to the ab sence of handshake. If any tests

fail

, follow
procedures in DUPINT and then DUP-CHL to resolve the prob lem. If you
replace any DUPINT hardware, wait to see if the standby SPE can be fully
restored to service.
3. If the above tests did n ot fai l, loc k the SPEs with t he SPE-sel ect sw itch es
and use the SPE-down interface to test the standb y components as
described in Chapter 4. If all tests pass, proceed to the next step. Replace
any component that fails testing . (Use the lock-and-power-d own
tech nique .) Bri ng the SPE bac k up as desc ribe d in C hapte r 4.
4. With the standby still busied out, issue the c ommand r to reboot the
standby SPE and immediately unplug the STANDBY terminal connector.
The standby should still be busied out. Wait for the yellow LED on the
stand by Pro cess or to b egin flashi ng, u nlock the SPEs, and mo nitor the
standby with status spe.
5. If han dshak e is es tabli shed , relea se the stand by SPE fro m bus yout an d
monitor its recovery with status spe. If the onset of memory shadowing or
refresh causes handshake to fail, then susp icion is cast on these standb y
circuit packs:
■DUPINT
■PKT-INT
■MEMORY
■MSSNET
Replace each of these in the stand by in the above order, using
lock -and -powe r-do wn. For e ach o ne, b ring u p the stand by SPE an d wai t
to see if handshake and memory refresh suc ceed.
Resolving Shadowing Failure
This section addresses the situation in which handshake communic ation is up,
but memory shadowing i s not on after reasonable initialization time, or is
repeatedly turning on and off. If the onset of memory shadowing is c ausing
handshake failure, see the prec eding section.
The following conditions p revent memory shadowing:
■Busyout of the standby SPE
■Locking of the SPEs by means of the SPE-select switches
