Disabling Auto BIOS Upgrade on SRX Series Services Gateways (CLI Procedure)

The auto BIOS upgrade feature is enabled by default. Users can disable the feature by using the CLI.

To disable the automatic upgrade of the BIOS on an SRX Series device:

1. Enter operational mode in the CLI.
2. Set the chassis routing-engine bios command.
   
   

   user@host> set chassis routing-engine bios no-auto-upgrade;

Note: The command disables automatic upgrade of the BIOS only during Junos OS upgrade or system boot-up. It does not disable automatic BIOS upgrade during loader installation.
