DL371 Audio System Engine
Operator Manual
Appendix B: Replacing A Module
Caution:
The module is a static-sensitive device. Proper grounding and
electrostatic discharge (ESD) precautions are required before
handling the module.
The design of the DL371 Audio System Engine makes module replacement very easy
and straightforward. The unit has rack guides in each of the seven module positions so
that the modules can slide easily in and out. Each module is held in place by two
screws.
To replace a module the only tool you will need is a Torx T10 screwdriver.
>> To remove a module
1 Switch off and electrically isolate the unit, as detailed in “To remove power from
(electrically isolate) the unit” on page 16. Then, disconnect all connectors from
the rear panel.
2 On the module you want to take out, remove the two securing screws (top and
bottom), as shown in Figure 1.
