SERVICING
SCOPE
Repair is by module replacement. Faulty modules are not repairable in the field. They should be
replaced by new modules and returned for repair.
Before fitting a new module ensure that the setting of the configuration links are the same as
that on the old module.
This module contains components that may be electrostatically sensitive. It should be
transported and stored in its original packaging material.
DIAGNOSIS
The TriBuild workstation is used for fault diagnosis. In the case of an Input/Output fault the
Health LED on the faulty module will be extinguished.
PREPARATION
To ascertain whether the chassis I/O slot containing the faulty module has been allocated a
hot repair partner, use one of the following methods:
•
Check the system drawings
•
Check the chassis wiring configuration
•
Use the I/O chassis Configuration Report on the TriBuild workstation.
Where there is a hot repair partner allocation, use the 'Dual-slot hot repair' procedure,
otherwise use the 'Single-slot hot repair' procedure.
CONFIGURATION
Before fitting a new module ensure that 321/320 link setting is the same as that on the old
module.
REMOVAL AND REPLACEMENT
Failure to take the faulty module off-line before removing it from the chassis could trigger a fault
alarm.
