This topic describes the following procedures:

1. Powering On the SRX220 Services Gateway
2. Powering Off the SRX220 Services Gateway
3. Resetting the SRX220 Services Gateway

Powering On the SRX220 Services Gateway

To power on the services gateway:

1. Ensure that you have connected the power supply to the device.
2. Insert the plug of the power supply adapter into an AC power source receptacle.
3. Turn on the power to the AC power receptacle and press the Power button.

The device starts automatically as the power supply completes its startup sequence. The Power LED lights green during startup and remains on when the device is operating normally.

Note: After the power supply is turned on, it can take up to 60 seconds for status indicators—such as the Status and Power LEDs—to show that the power supply is functioning normally.

Note: If you want to power the device off immediately after you power it on, we recommend that you shut down the device using the command-line interface (CLI) request system power-off command.

Powering Off the SRX220 Services Gateway

You can power off the services gateway in one of the following ways:

• Graceful shutdown—Press and release the Power button. The device begins gracefully shutting down the operating system and then powers itself off.

  Note: Do not press the Power button again while the device is shutting down.

• Forced shutdown—Press the Power button and hold it for more than 10 seconds. The device immediately powers itself off without shutting down the operating system.

  Caution: Use the graceful shutdown method to halt, power off, or reboot the services gateway under normal circumstances. Use the forced shutdown method as a last resort to recover the services gateway if the services gateway software does respond to the graceful shutdown method. Forced shutdown can result in data loss and corruption of the file system.

  Note: To remove power completely from the device, unplug the AC power cord or switch off the power source. After powering off a power supply, wait at least 10 seconds before turning it back on. After powering on a power supply, wait at least 10 seconds before turning it off. The Power button on the services gateway is a standby power switch. If you press the Power button to power off the device when it is still connected to a power source, 12 V (SRX220H model) or 48 V (SRX220H-POE model) power will still be available in the chassis and the device will be fully powered off.

Tip: When you are powering off the device, the system displays the following message: Turning the system power off. You can now safely remove the power cable to completely disconnect the power from the device.

Note: You can use the request system reboot command on the CLI to schedule a reboot of the services gateway.

For more information about halting, powering off, or rebooting the services gateway using the CLI, see the Junos OS Administration Guide.

Resetting the SRX220 Services Gateway

The Reset Config button located at the front panel of the services gateway resets the device configuration in either of two ways:

• Pressing the Reset Config button briefly reverts the device configuration to the configuration in use when the device was last started.
• Pressing and holding the Reset Config button for 15 seconds or more deletes all configurations on the device and loads and commits the factory configuration.

The button is recessed in the front panel to prevent it from being pressed accidentally.
