The
test duplication-interface
command performs hardware diagnostic tests on
the system’s dupint circuit packs and interconnecting cable (DUPINT and
DUP-CHL maintenance objects). Testing is under control of the active SPE. See
descriptions of these maintenance objects in Chapter 9 for more details.
The DUP-CHL maintenance object is associated with both active and standby
DUPINT boards and the interconnecting cable. The DUPINT maintenance object
is associated with the active dupint board. There are five tests for the DUPINT
maintenance object and an additional eight tests for the DUP-CHL maintenance
object.
When testing the active and standby dupint circuit packs and the interconnection
cable for an active SPE carrier, duplication channel components are only tested
in one direction. By performing an SPE interchange, the duplication channel
components can be tested in the other direction for complete testing. Further
testing of the standby dupint board can also be done through the SPE-down
Command Interface with carriers locked. This interface can be used for general
testing of the standby SPE when the SPE handshake is not functioning.
The duplication-interface test is invalid for an SPE simplex system. For SPE
duplex systems, the presence of both DUPINT boards is assumed. In duplex
SPE systems, any DUPINT communication failures will give FAIL or ABORT
results on the output screen.
Loss of handshake between active and standby SPEs prevents testing of
standby SPE components unless the SPE-down interface is used.
The
long
test sequence is destructive and requires that
busyout spe-standby
be executed first.
Output
Port The physical address of the maintenance object that is being tested.
For DUPINT the address is the cabinet (1) and carrier (A or B) of the
active SPE. For DUP-CHL, the address is the cabinet and carrier of the
standby SPE.
