SECTION 7 - REPAIR/REPLACEMENT PROCEDURES
INTRODUCTION
This section explains the replacement procedures for a Digital
Slave Output (DSO) module. There are no special tools
required to replace an DSO module.
MODULE REPAIR/REPLACEMENT PROCEDURES
If you determine the DSO 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. 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 settings. 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 guide rails in the MMU; gen-
tly slide it in until the front panel is flush with the top and bot-
tom 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.
6. Return to normal operation.
CAUTION
Disable the digital output signals before removing the module
to prevent damage to the edge connector (P3) pins.
ATTENTION
Invalider les signaux de sortie numerique avant de retirer le
module afin d'eviter d'endommager les broches du connecteur
plat (P3).
