Procedure for SPE-Down Mode
Due to fatal hardware and software probl ems, it is possible for a system to g o into
SPE-Down Mode. In this mode, the system invokes emergenc y transfer and does
not provide any other service. Moreover , while in this mode, the software cannot
run at all. However, there are two limited interfac es to the system:
■The Processor circuit pack is resp onsible for maintenance and serves as
interface to the system.
■The administration terminal, which con nects directly to the p rocessor,
provides a very limited interface to the system. Technicians can d isplay
alarms or restart the system. Only a subset of c ontrol complex alarms
displays.
The fol lowin g ar e samp le d isp lays for SPE-D own mo de a nd t he ala rms

**************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 locati on of the problem. It is possib le for two or
more circuit packs to h ave failed. It is also possibl e for a fatal problem with one
circuit pack to affec t another circuit pac k, especially the Processor c ircuit pack.
All three of the following methods should be employed to determine where the
fatal fault lies.
