Connecting the SRX340 to Power

Required Tools and Parts for Grounding the SRX340 Services Gateway

To ground and to provide power to the services gateway, you need the following tools:

  • Phillips (+) screwdrivers, numbers 1 and 2

  • Electrostatic discharge (ESD) grounding wrist strap

  • Wire cutters

Connecting the SRX340 Firewall Grounding Cable

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the SRX340 Firewall to earth ground before you connect power to the services gateway.

You ground the services gateway by connecting a grounding cable to earth ground and then attaching it to the chassis grounding point located on the side of the device using the Panduit LCD8-10A or equivalent grounding lug (provided) and two #10-32 UNF screws (provided). You must install the SRX340 in a restricted-access location and ensure that the chassis is always properly grounded. The SRX340 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.

You must provide the grounding cable (#8 AWG or as permitted by the local code).

CAUTION:

Before you connect power to the services gateway, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the services gateway (for example, by causing a short circuit).

To ground the device:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis. 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.
  4. Place the grounding cable lug over the grounding point (sized for #10-32 UNF screws) on the side of the chassis as shown in Figure 1.
  5. Secure the grounding cable lug to the grounding point, first with the washer, then with the screws.

  6. 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.

Note:

The device should be permanently connected to ground during operation.

Connecting the SRX340 Firewall to an AC Power Supply

You connect AC power to the services gateway by attaching a power cord from the AC power source to the AC appliance inlet located on the power supply faceplate. To connect the device to the power supply:

Note:

The services gateway must be connected to earth ground during normal operation. The protective earthing terminal on the side of the chassis is provided to connect the services gateway to ground.

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the other end of the ESD strap to the ESD point on the rack.
  2. Insert the appliance coupler end of the power cord into the appliance inlet on the power supply faceplate.
    Note:

    We strongly recommend that you use only the 3-prong power cord supplied with your services gateway.

  3. Insert the power cord plug into an external AC power source receptacle as shown in Figure 2. Verify that the power cord does not block the air exhaust and access to services gateway components or drape where people could trip on it.

CAUTION:

We recommend using a surge protector for the power connection.

Powering On the SRX340 Services Gateway

To power on the services gateway:

  1. Insert the power cord plug into an AC power source receptacle.
  2. Turn on the power to the AC power receptacle.

The device starts automatically as the power supply completes its startup sequence. The PWR LED lights 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 STAT and PWR LEDs—to show that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

Note:

When the system is completely powered off and you turn on the power supply, the device starts as the power supply completes its startup sequence. If the device finishes starting and you need to power off the system again, first issue the CLI request system power-off command.

Powering Off the SRX340 Services Gateway

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.

    CAUTION:

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

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

    CAUTION:

    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.

Warning:

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

CAUTION:

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

Note:

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.

Tip:

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.

Note:

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