Halting a Services Router with the CLI

You can use the request system halt CLI command to halt the Services Router:

user@host> request system halt <at time> <in minutes> <media type> <message “text”>

When the router is halted, all software processes stop and you can access the router through the console port only. Reboot the router by pressing any key on the keyboard.

NOTE: If you cannot connect to the router through the console port, shut down the router by pressing and holding the power button on the front panel until the POWER LED turns off. After the router has shut down, you can power on the router by pressing the power button again. The POWER LED lights during startup and remains steadily green when the router is operating normally.

Table 102 on page 196 describes the request system halt command options.
