Module Repair and Replacement

WBPEEUI240769B0
This section explains the replacement procedures for the
IMCIS22 and IMQRS22 modules. There are no special tools
required to replace the I/O modules.
If an I/O module is faulty, replace it with a new one. Do not
to repair the module; replacing components may affect the
module performance. The module can be removed while sys-
tem 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 module mounting unit.
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 I/O module,
align the replacement I/O module with the guide rails in the
module mounting unit. Gently slide it in until the front panel
is flush with the top and bottom of the module mounting unit
frame.
5. Push and turn the two captive retaining screws on the
module front panel 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.
