Chapter 2 Preparing for Installation
Checking Hardware and Software Compatibility
Catalyst RSM/VIP2 routers are compatible with the PA-E3, use the show version command to display
the current hardware configuration of the router, including the system software version that is currently
loaded and running.
You can check the version of the default ROM image by removing the board and checking the ROM
labels, or by configuring the interface or system software to boot from ROM, restarting the system, and
using the show version command to check the running version.
To display the current system software version, use the show version command. In the following
example, the running system software is Cisco IOS Release 11.1(16)CA.

If your system lacks the required system software and microcode, contact a customer service
representative for upgrade information.
Checking Hardware and Software Compatibility
To check the minimum software requirements of Cisco IOS software with the hardware installed on your
router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether
modules within a system are compatible, but it does provide the minimum IOS requirements for
individual hardware modules or components.
Note
Access to this tool is limited to users with Cisco.com login accounts.
To access Software Advisor, click Log In at Cisco.com and go to Support > Tools and Resources. You
can also access the tool by pointing your browser directly to

Choose a product family or enter a specific product number to search for the minimum supported
software release needed for your hardware.
