Circuit Pack) Maintenance documentation. These tests are run on the
PI-BD (Processor Interface Circuit Pack) Maintenance object.
SCI Start Test (#176)
This test is destructive.
This test restarts the System Communication Interface. This implies all BX.25
(DCS, AUDIX, mis, etc.) and ISDN links are restarted. The checksum of the
downloadable firmware is tested. If the checksum fails, the firmware is
redownloaded from tape. If it passes, SCI Start completes and the associated
BX.25 and ISDN Links are started up. If a circuit pack needs to be replaced, refer
to Chapter 6, ‘‘
Reliability Systems: A Maintenance Aid’’ for instructions on
replacing an SPE circuit pack.
The Processor Interface circuit pack firmware is downloaded from the flash ROM
memory of Processor circuit pack. If the checksum test fails, then the firmware is
re-downloaded again from Processor circuit pack. If it passes, SCI Start
completes and the associated BX.25 and ISDN links are started up. If the
checksum failure persists, refer the footnote (b) of Hardware Error Table for
repair procedure.
