SECTION 7 - REPAIR/REPLACEMENT PROCEDURES
INTRODUCTION
This section explains the replacement procedures for the RIO
module. There are no special tools required to replace the
module.
MODULE REPAIR/REPLACEMENT
If you determine that the module is faulty, replace the faulty
module 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
remove and 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. One of the follow-
ing situations occurs when the RIO is removed from the MMU:
a. When the RIO is located on the local expander bus, all
remote modules go to a default setting.
OR
b. When the RIO is located on a remote expander bus, the
remote node is marked off-line. All associated remote slave
modules go to the default setting.
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 MMU; gen-
tly slide it in until the front panel is flush with the top and bot-
tom of the MMU frame.
WARNING
The RIO module MUST be stopped before removal. The output
status of slaves may incorrectly change if an active RIO is
removed before being properly stopped.
AVERTISSEMENT
Le module RIO doit place en mode arret avant d'etre retire du
chassis. L'etatdes sorties des modules asservis pourrait
changer de facon erronee si un module RIO actif est retire
