SECTION 7 - REPAIR/REPLACEMENT PROCEDURES
INTRODUCTION
This section explains the replacement steps for an Digital Slave
Module (IMDSM05). There are no special tools required to
change the DSM.
MODULE REPAIR/REPLACEMENT
If you determine the DSM is faulty, replace it with a new one.
DO NOT try to repair the module; replacing components may
affect the module performance. You can remove the module
while system power is supplied.
NOTE: Ensure that the replacement module switch and jumper set-
tings are the same as the original module.
To replace a module:
1. Push and turn the two front panel captive retaining screws
one half turn to unlatch the module. It is unlatched when the
slots on the screws are vertical and the open end of the slots
face away from the module.
2. Gently slide the module out of the MMU.
3. Configure the replacement module switch and jumper set-
tings. Ensure they are set the same as the original module.
4. In the same slot assignment as the original module, align
the replacement module with the plastic guide rails in the
MMU. Gently slide it in until the front panel is flush with the
top and bottom of the MMU frame.
5. Push and turn the two captive retaining screws on the
module faceplate one half turn to the latched position. It is
latched when the slots on the screws are vertical and the open
ends face the center of the module. (To remove the module,
turn the module retaining screws to the unlatched position
and gently slide out).
6. Return to normal operation.
