Replacing the 5U Library Control Module
These instructions explain how to remove a 5U control module and replace it with a 5U control module field
replaceable unit (FRU). You may need to replace the control module if its chassis is severely damaged.
Typically, however, only certain customer replaceable units (CRUs) or FRUs within the control module need
to be replaced.
There are no restrictions on where the control module can be installed in the library configuration. However,
the recommended placement of a control module in a 14U library configuration is on top of the 9U expansion
module.
Before removing the 5U control module from a 14U library configuration, you must first remove the
expansion module (if any) positioned above the control module.
Preparing to Remove the 5U Control Module
Required tools:
• Phillips #2 screwdriver, for removing and replacing the top cover plate
• T10 TORX screwdriver, for removing and replacing the bottom cover plate
1 Power off the library.
2 Disconnect all power cords, network data cables, and module-to-module cables from any expansion
module located above the control module, and from the control module itself.
3 Remove all power supplies from each module that you intend to remove. For details, see Adding,
Removing, and Replacing Power Supplies on page 136.
4 Remove all tape drives from each module that you intend to remove. For details, see Adding, Removing,
and Replacing Tape Drives on page 148.
5 Remove the tape cartridges from each module that you intend to remove.
Note
If you have applied a Capacity-On-Demand (COD) license key to the original
control module, you will need to get a replacement license key to apply to the
new control module
