Start by determining the time of the interchange. Then, examine the alarm and 
error logs as described in the following section. If that does not identify the 
problem, proceed to the next section, which describes a sequence of tests of the 
standby SPE.

Examining the Alarm and Error Logs
The system may have had time to log alarms or errors against the fault the 
caused the interchange. Proceed through the steps summarized in the following 
flowchart. Examine only major alarms with a timestamp near the time of 
interchange, and whose carrier designation is...

Testing the Standby SPE
The system may not have had time to log errors against the failed component 
that caused the spontaneous interchange. If you have progressed through the 
preceding flowchart without determining the cause of interchange, test the 
standby for faults by proceeding through the following...

Executing a Planned SPE Interchange
Planned SPE interchanges are initiated on demand by the reset system 
interchange command, or automatically by scheduled daily maintenance. The 
latter is administered with the system-parameters maintenance screen. A 
planned interchange normally has no perceivable...

If the SPE is locked by means of the SPE-SELECT switches, error 607, auxiliary 
data 1153, is logged against SYSTEM. If the switches are not locked and the 
interchange fails, an unalarmed error 605 is logged against SYSTEM. The 
auxiliary code associated with this error indicates which aspect of the...

Notes for SYSTEM Error 605 AUX Data:
1. Follow repair instructions in ‘‘
STBY-SPE (Standby SPE Maintenance)’’ for 
the particular standby SPE problem. After fixing that problem, try the 
interchange again. 
2. Mass Storage System is in use. Check Disk and Tape LEDs for activity.

Fiber Fault Isolation Procedure
Use the following procedure to isolate faults on a fiber-link. When troubleshooting 
a system with duplicated Port Network Connectivity (PNC), first busyout 
pnc-standby before busying out a standby Fiber-Link (FIBER-LK), Expansion 
Interface (EXP-INTF), Switch Node Interface...

Wait 5 minutes for any SNI-BD or SNI-PEER alarms to clear. (You 
can speed this process with clear firmware counters [a-pnc | 
b-pnc] for the PNC that was repaired).
