tools required to replace a DSO module.
MODULE REPAIR/REPLACEMENT
If the DSO is faulty, replace it with a new one.

try to
repair the module; replacing components may affect the mod-
ule performance. You can remove the module while system
power is supplied. To replace a module.
1. Drive the module’s relays to a non-active status.
2. Disconnect the relay power supply (24 VDC).
3. 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.
4. Gently slide the module out of the MMU.
5. Configure the replacement module switch settings. Ensure
they are set the same as the original module.

the replacement module with the guide rails in the MMU; gently
slide it in until the front panel is flush with the top and bottom
of the MMU frame.

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.

vent damage to the edge connector pins.
