# boot system

#### Syntax

boot system relFileName

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Specifies the software release (.rel) file to use on reboot. There is no no version.

| Note: In a dual SRP module configuration, when this information is synchronized to the standby SRP module, the standby SRP module is reloaded to boot the specified release. The high availability feature requires the release to be the same on the active and the standby SRP modules. This means that arming the system to boot with a different release causes the standby module to reload and prevent high availability from becoming active or to disable high availability if it is active or pending.

#### Options

- relFileName—Name of the software release file (.rel) that contains the software release

#### Mode

Global Configuration
