Part 7: Troubleshooting Common ROMMON Upgrade Issues

| Problem | Likely Cause | Solution | |---------|--------------|----------| | Package not supported | Wrong platform file | Verify you downloaded the ASR1000-specific ROMMON, not for ASR1001-X (different). | | Upgrade hangs at 99% | Corrupt bootflash sector | Reformat bootflash: format bootflash: then retry. | | After reload, ROMMON still old | Upgrade not committed | Re-run with commit flag or use install commit. | | Router powers off during upgrade | Power supply issue | Never upgrade ROMMON on a marginal PSU. Use redundant PSUs. | | USB boot fails after upgrade | Incompatible USB format | Reformat USB to FAT32 with MBR, not GPT. |
