Carrier Card Summary
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 carrier cards or SPAs within a system are compatible, but it does provide the minimum Cisco 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, type "Software Advisor" in the SEARCH box, and click GO. Click the link for the Software Advisor tool.
Choose a product family or enter a specific product number to search for the minimum supported software release needed for your hardware.
SPA Blank Filler Plates
SPA blanks are available to fill and unused SPA slot.
Note When a SPA slot is not in use, a SPA blank filler plate must fill the empty slot to allow the router or switch to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the SPAs. If you plan to install a new SPA in a slot that is not in use, you must first remove the SPA blank filler plate.
