Repair and Replacement
Introduction
This section explains the replacement steps for a IMASI13
module (ASI). There are no special tools required to replace an
ASI module.
NOTE:
Refer to Appendix B for information about replacing an IMASI03 mod-
ule with an IMASI13 module.
Module Repair and Replacement
If the ASI module is faulty, replace it with a new one. Do not
try to repair the module; replacing components may affect the
module performance. Modules can be removed while system
power is supplied. To replace a module:
1. Push and turn the two front panel captive latches one half
turn to unlatch the module. It is unlatched when the slots on
the latches are vertical and the open end of the slots face away
from the center of the module.
2. Gently slide the module out of the module mounting unit
(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 guide rails in the module
mounting unit. 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 latches on the module face-
plate one half turn to the latched position. It is latched when
the slots on the latches are vertical and the open ends face the
center of the module.
6. Return to normal operation.
