6.3 Replacing Subsystem Components
6.3.1 Replacing Controller Module
When replacing a failed Controller Module, please follow these steps:
1. Loosen the thumbscrews on the sides of the Controller Module case.
2. Use the Controller handle to pull out the defective Controller.
3. Insert and slide the new Controller in. Note that it may be necessary to remove
the old/defective Controller Module from the case and install the new one.
IMPORTANT: When the subsystem is online and a Controller module
fails and the replacement is not yet available, in order to maintain
proper airflow within the enclosure, the failed module can be
removed from the enclosure and the Plate Cover for Controller can
be used in place of the failed module. (Refer to next section).
When replacing a failed component online, it is not recommended
to remove the failed component for a long period of time; proper air
flow within the enclosure might fail causing high controller/disk
drive temperature.
4. Tighten the thumbscrews on the sides of the Controller Module case.
