Replacing media bay modules
When media bay modules require replacement, follow the steps in this section.
Figure 56 Process map: Replacing a media bay module
If a media bay module fails, follow this procedure to properly replace the module.
1 Follow the steps in “Shutting down the system” on page 152 to ensure the system shuts down
correctly.
2 Remove the front bezel from the unit where the module resides.
3 Pull the latch beside the module to be replaced to release the module. Refer to Figure 54 on
page 153 .
4 Slide the module out of the bay where it is installed.
5 Record the switch settings from the old module.
Warning: This section describes replacing a module with the same type of module. If you
want to replace a module with a different type of module, you must treat it as a new
installation. Refer to
Chapter 7, “Setting media bay module DIP switches,” on page 135
and review Figure 51 on page 140 to ensure the new module does not overrun any lines
already assigned to other modules.
