Install mode is the newer and recommended mode to run. This breaks the .bin file up into smaller .pkg files that must be loaded into memory independently of each other, and allows you to boot faster and utilize memory better.
The .bin file that you download from software.cisco.com has all the .pkg files you need inside.
Note
|
Think of the .bin file as a .zip file. It is able be extracted to obtain the .pkg files. There is also a configuration file that is used to indicate what .pkg files are needed. This is the process that is used
when you boot in install mode.
|
-
The boot statement is looked at to determine what configuration file to load (usually packages .conf).
-
The configuration file is opened and used to sort out what .pkg files to load.
-
The .pkg files are loaded and Cisco IOS completes the boot process.
Note
|
This is done automatically and you never have to edit this file directly. However, you can check what package files the .conf file is pointed to before you do a reload to ensure it is pointed to the right ones.

When you perform an upgrade in install mode, the process is always the same.
-
Copy the new .bin file onto the switch.
-
Extract the .pkg files from the .bin file.
-
Update the .conf file and reload the device into the new version.
Most of the time all these steps can be accomplished with a single command .
Note
|
By default all IE-9300 series switches ships in install mode.
|
To verify the mode the switch is operating on currently use the show version command.
