Repair Procedures for High and Critical Reliability
Handling SHDW-CIR and SHDW-LNK Alarms in
the Active SPE
Check for the existence of SHDW-CIR alarms against the Active SPE Duplication
Interface circuit pack or SHDW-LNK alarms. If there are Active SPE SHDW-CIR
or SHDW-LNK alarms, inform the customer that a COLD 2 restart of the system is
needed and determine a time at which to restart may be. At that time, complete
the following steps:
1. Make sure that the tape (memory card) in the Active SPE tape unit
(memory card slot) has the most current translations. If it does not, issue
the save translations spe-active command to put the most current
translations on it.
2. Exchange the tapes (memory cards) in the Active SPE and Standby SPE
so that the Standby SPE tape unit (memory card slot) contains the tape
(memory card) from the previous step.
3. For a 386 system, if the Standby SPE is not in standby mode, issue the
refresh spe-standby command to put it into standby mode if possible (see
the previous Note). If the Standby SPE was successfully put into standby
mode, then issue the reset system interchange command to cause a
PEI. If the refresh or system interchange are unsuccessful, then use the
SPE select switches to hard select the Standby SPE (this will result in a
COLD 2 restart of the system).
4. If the upgrade software (reset system interchange) command is
successful, an SPE-interchange results in the new Active SPE performing
a COLD 2 (HOT) restart. Follow the "Circuit Pack Replacement Procedure"
described later. If the upgrade software command failed, determine why
the failure occurred, resolve the problem, and repeat this entire procedure.
Handling DUPINT Alarms in the Active SPE
Check for the existence of DUPINT alarms against the Active SPE Duplication
Interface circuit pack. If there are Active SPE DUPINT alarms, inform the
customer that a reboot of the system may be required and determine a time at
which a reboot may be done. At that time, complete the following steps:
1. Make sure that the translation card in the Active SPE has the most current
translations. If it does not, issue save translations spe-active to put the
most current translations on it.
2. Exchange the translation cards in the Active SPE and Standby SPE so that
the Standby SPE contains the card with the most current translations.
3. Throw the SPE Select Switches on the TN772 Duplication Interface circuit
packs to force an SPE-interchange so that the current Standby SPE
becomes the new Active SPE.
If the Duplication Interface circuit pack actually severed the Memory
Shadowing Link resulting in corruption of Standby SPE Memory, the
SPE-interchange results in the new Active SPE performing a Reboot.
