Procedure for SPE-Down Mode
Due to fatal hardware and software problems, it is possible for a system to go into
SPE-Down Mode. In this mode, the system invokes emergency transfer and does
not provide any other service. Moreover, while in this mode, the software cannot
run at all. However, there are two limited interfaces to the system:
■ The Processor circuit pack is responsible for maintenance and serves as
interface to the system.
■ The administration terminal, which connects directly to the processor,
provides a very limited interface to the system. Technicians can display
alarms or restart the system. Only a subset of control complex alarms
displays.
The following are sample displays for SPE-Down mode and the alarms
displayed.
**************SPE DOWN MODE*************
You can display alarms and reset system(4).

* The “MAINT” designation is used for PR-MAINT.
The first step is to determine the location of the problem. It is possible for two or
more circuit packs to have failed. It is also possible for a fatal problem with one
circuit pack to affect another circuit pack, especially the Processor circuit pack.
All three of the following methods should be employed to determine where the
fatal fault lies.
