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).

shows all possible SPE-Down alarms.

* 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.
