Removing the standard I/O book
Use this information for instructions on how to remove the standard I/O book.
Before you remove the standard I/O book, take the following steps to save data, firmware, and configuration
information.
Note: If the IMM in the standard I/O book being replaced is inaccessible using software tools, you will not be
able to use the IMM to gather component information needed to complete the replacement. This information
must then be manually gathered by disassembling components and reading the information on component
labels. Links are provided to removal and replacement procedures that provide label access for components
external to the standard I/O book, such as the front operator panel assembly, LCD system information
display panel, and midplane.

Features on Demand (FoD) inventory and keys, system machine type, system model number, system
product identifier, system serial number, Universal Unique Identifier (UUID), and system asset tag of the
