Software and Hardware Requirements
The table below lists the minimum Cisco IOS software release required to use the OC12 POS line card
in the Cisco 7304 router.
For all systems in which you install the OC12 POS line card, use the show version command to display
the current configuration of the router, including the system software version that is currently loaded and
running. Use the show diag slot command to view specific information about the hardware installed in
your system.
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 Login at Cisco.com and go to Technical Support Help—Cisco
