Instead, use the bundle install router# bundle install flash:c800-universalk9-mz.SPA.158- Use code with caution. Copied to clipboard
Understanding the filename is essential for network administrators to ensure compatibility before deployment. The filename c800-universalk9-mz.SPA.158-3.M9.bin can be deconstructed as follows:
Once the console line responds, verify that the router is correctly running the version 15.8(3)M9 operating system:

: Older hardware models may run out of DRAM during runtime decompression. If you notice erratic interface behavior or crash dumps, look for %SYS-2-MALLOCFAIL errors in your console logs, which indicate you must upgrade the physical memory modules on the router or downgrade to a smaller footprint image.
