Ensure all cards, line cards, and service processors return to an "ok" or "inserted" operational state. Troubleshooting Common Issues

The asr1000-rommon.173-1r.spa.pkg updates the code. It does not update the FPGA bitstreams on the SIP (Shared Port Adapter) or ESP cards. Those are usually handled by other .pkg or .bin files found in the main IOS-XE bundle.

Operating system upgrades on enterprise edge routers are not limited to the IOS XE .bin files. ROMMON firmware must scale alongside the software features to support modern security protocols, underlying hardware microcode changes, and bug fixes.
