Connecting the SRX380 to Power

Required Tools and Parts for Grounding the SRX380 Firewall

Table 1 lists the earthing terminal location, grounding cable requirements, grounding lug specifications, screws and washers required, and the screwdriver needed for connecting the device to earth ground. Before you begin connecting a device to earth ground, ensure that you have the parts and tools required for your device.

Connecting the SRX380 Grounding Cable

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the chassis to earth ground before you connect it to power.


Ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable you supply. Using a grounding cable with an incorrectly attached lug can damage the device.

You ground the services gateway by connecting a grounding cable to earth ground and then attaching the grounding cable to the chassis grounding point located on the rear of the device.

You must install the SRX380 in a restricted-access location and ensure that the chassis is always properly grounded. The SRX380 has a two-hole protective grounding terminal provided on the chassis. See Figure 1. Under all circumstances, use this grounding connection to ground the chassis. For AC-powered systems, you must also use the grounding wire in the AC power cord along with the two-hole grounding lug connection. This tested system meets or exceeds all applicable EMC regulatory requirements with the two-hole protective grounding terminal.

To ground the device:

  1. Wrap and fasten one end of the ESD grounding strap around your wrist and connect the other end to a site ESD point. For more details, see Prevention of Electrostatic Discharge Damage.
  2. Ensure that all grounding surfaces are clean and brought to a bright finish before grounding connections are made.
  3. Connect the grounding cable to a proper earth ground, such as the rack in which the device is mounted.
  4. Remove the two screws on the chassis using a Phillips screwdriver.
  5. Place the grounding cable lug attached to the grounding cable over the grounding point on the rear of the chassis.

  6. Secure the grounding cable lug to the grounding point with the washers and screws.
  7. Dress the grounding cable and verify that it does not touch or block access to the services gateway components and that it does not drape where people could trip on it. Ensure that the cable does not obstruct the air flow of the fans.


The device should be permanently connected to ground during operation.

Connecting the SRX380 Firewall to an AC Power Supply

Ensure that you have the following parts and tools available:

  • A power cord appropriate for your geographical location

  • A power cord retainer clip (provided with the device)

To connect AC power to the device:

  1. Push the end of the power cord retainer strip into the slot above the power cord inlet until the strip snaps into place. Ensure that the loop in the retainer strip faces the power cord (see Figure 2).

    The power cord retainer clip extends out of the chassis by 3 in. (7.62 cm).

  2. Press the small tab on the retainer strip to loosen the loop. Slide the loop until there is enough space to insert the power cord coupler into the power cord inlet.
  3. Locate the power cord or cords shipped with the device; the cords have plugs appropriate for your geographical location. See Table 4.

    Ensure that the power cord does not drape where people can trip on it or block access to device components.

  4. Insert the power cord coupler firmly into the power cord inlet (see Figure 2).
  5. Slide the loop toward the power supply until it is snug against the base of the coupler.
    Figure 2: Connecting an AC Power Cord Connecting an AC Power Cord
  6. Press the tab on the loop and draw out the loop into a tight circle.
  7. If the AC power source outlet has a power switch, set it to the OFF (0) position.
  8. Insert the power cord plug into an AC power source outlet.
  9. If the AC power source outlet has a power switch, set it to the ON (|) position.

    If the power supply is installed correctly and functioning normally, the LED on the faceplate of the power supply glows solid green.

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


    After the power supply is turned on, it can take up to 60 seconds for status indicators—such as the STAT and PWR LEDs—to show that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

Powering Off the SRX380 Firewall

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

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


    Use the graceful shutdown method to power off or reboot the services gateway.

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


    Forced shutdown can result in data loss and corruption of the file system.

    Use the forced shutdown method as a last resort to recover the services gateway if the services gateway operating system is not responding to the graceful shutdown method.


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

To remove power completely from the device, unplug the power cord or switch off the AC 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, which will not turn off the input power to the services gateway.


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


You can use the request system reboot CLI command to schedule a reboot.
