SERVICING
SCOPE
System repair is by module replacement. Faulty modules are not repairable in the field; they
should be replaced by new modules and returned for repair.
CAUTION 1
The module contains components that may be electrostatically sensitive. It should be
transported and stored in its original packaging material.
CAUTION 2
Before fitting a new module ensure that the setting of all three links is the same as that on the
old module.
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
The only configuration necessary is the correct setting of the three links which are shown in
Figure 1-1. Ensure that the link configuration on the new module is the same as that on the old
module.
