Reboot and Halt SRX Series Firewall

Learn about restarting and halting SRX Series Firewalls, including rebooting, through CLI and J-Web.

Reboot the SRX Series Devices

This example shows how to reboot an SRX Series Firewall.

Requirements

Before rebooting the firewall, save and commit any Junos OS updates.

Overview

This example shows how to reboot a firewall fifty minutes from when you set the time from the internal media while sending a text message of ’stop’ to all system users before the firewall reboots.

Procedure

CLI Quick Configuration

To configure this section quickly, follow these steps:

  1. Copy the commands and paste them into a text file.

  2. Remove any line breaks and adjust details to match your network.

  3. Copy and paste the commands into the CLI at the [edit] level.

  4. Enter commit from configuration mode.

From operational mode, enter:

GUI Quick Configuration
Step-By-Step Procedure

To reboot an SRX Series Firewall:

  1. In the J-Web user interface, select Device Administration>Software Management>Reboot.

  2. Select Reboot in 50 minutes to reboot the device fifty minutes from the current time.

  3. Select the internal (for SRX Series Firewalls) boot device from the Reboot From Media list.

  4. In the Message box, type stop as the message to display to any user on the device before the reboot occurs.

  5. Click Schedule. The J-Web user interface requests confirmation to perform the reboot.

  6. Click OK to confirm the operation.

    • If the reboot is scheduled to occur immediately, the device reboots. You cannot access J-Web until the device has restarted and the boot sequence is complete. After the reboot is complete, refresh the browser window to display the J-Web login page.

    • If the reboot is scheduled to occur in the future, the Reboot page displays the time until reboot. You have the option to cancel the request by clicking Cancel Reboot on the J-Web user interface Reboot page.

  7. Click OK to check your configuration and save it as a candidate configuration.

  8. If you are done configuring the device, click Commit Options>Commit.

Step-by-Step Procedure

The following example requires you to navigate various levels in the configuration hierarchy. For instructions on how to do that, see Using the CLI Editor in Configuration Mode.

To reboot a device:

  1. In operational mode, schedule a firewall reboot for fifty minutes from the set time on the internal media. Send a 'stop' text message to all system users before the device reboots.

    Enter:

Results

From configuration mode, confirm your configuration by entering the show system command. If the output does not display the intended configuration, repeat the configuration instructions in this example to correct it.

If you are done configuring the firewall, enter commit from configuration mode.

Verification

Confirm that the configuration is working properly.

Verifying the Firewall Reboot

Purpose

Verify that the firewall rebooted.

Action

From operational mode, enter the show system command.

Halt the SRX Series Firewalls

This example shows how to halt a device.

Requirements

Before halting the firewall, save and commit any Junos OS updates.

Overview

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

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

This example shows how to halt the system and stop software processes on the device immediately.
