FIPS mode gateway replacement checklist

Last Updated : Mar 12, 2026 |

Step

Procedure/Action

CLI command/Note

Pre-replacement (backup procedure)

Save running config

Required: Save the current running configuration.

copy running-config startup-config

Record security info

Required. Configuration master key cannot be modified in FIPS mode, so certain security-related data is not restored. Record the necessary information.

  • show usernames

  • show snmp user

  • show gw-identity h248reg | syslog..

Check announcements location and SW load

Required. Record the current load version and the announcement storage location (Compact flash or Internal).

show system

To see announcement files:

show announcements files brief

Record SNMP Engine ID

Recommended. Record the current SNMP Engine ID to maintain it on the new board.

show snmp engineID

Perform backup

Required. Perform the backup to a directory on the USB drive.

backup config usb usbdevice0 <backup-dir>

Safe removal

Required. Safely remove the USB drive.

safe-removal usb usbdevice

Post-replacement (restore procedure)

Initial new board login

Login with default credentials (root, root), answer EASG questions, skip the configuration script, and disable DHCP.

Respond n to configuration script and y to remove DHCP.

Enable FIPS mode

Required. Configure the gateway for FIPS mode. The gateway will reset, and you must repeat step II.1 afterward.

set fips-mode enable

Update software load

Check and update. If the new board's software load is older than the backup's, update it manually or include the software image in the backup folder for automatic update during restore.

show system to check; place downloadable image.

g430v3_sw_....bin in backup directory for automatic software update during the restore.

Manual configuration to restore non secure data

Recommended. Manually edit startup_config.cfg on the USB drive to remove all encrypted-* lines.

Edit the startup_config.cfg and remove all encrypted-* lines.

Restore from USB

Restore will fail if step 5 was not done due to the secure configuration key mismatch (keys are unique to each gateway).

restore usb usbdevice0 <backup-dir> [announcements-location]

Manual password/config Save

Required. After the restore, login with the default password, configure a new password, and save the configuration.

copy running-config startup-config

Restore recorded security info

Required. Manually reload the usernames, SNMPv3 users, and TLS certificates that were recorded in step I.2.

username snmp username

copy scp/usb gw-identity-cert commands for certificates.

Restore SNMP Engine ID

If needed. Set the old SNMP Engine ID.

snmp-server engineID <engineID>

(using the value recorded in Step I.3).
