Replacing the SFB on the SRX3400 Services Gateway


The SFB is accessible from the front panel, in the topmost slot. It weighs approximately 5.1 lb (2.3 kg). Before you replace the SFB, you must power off the services gateway.

To replace an SFB:

  1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic Discharge Damage to the SRX3400 Services Gateway.
  2. If you have not already done so, power off the services gateway by pressing the Power button on the front panel of the SFB for three to five seconds.

    The PWR LED blinks to show you that the services gateway is shutting down. Wait for the services gateway to shut down before you proceed to the next step.

  3. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  4. Disconnect any cables attached to the SFB front panel connectors.
  5. Loosen the screws on either end of the SFB front panel.
  6. Pull open the ejector handles and slide the SFB halfway out of the chassis.
  7. Place one hand underneath the SFB to support it and slide it completely out of the chassis.
  8. Place the SFB on the antistatic mat.

  9. Carefully align the sides of the replacement SFB with the guides inside the chassis.
  10. Slide the SFB into the chassis until you feel resistance.
  11. Grasp both ejector handles and press toward the center of the card to fully seat the SFB.
  12. Tighten the screws on either side of the card.
  13. Reconnect the cables, if any, that you disconnected from the SFB front panel connectors in Step 4.

  14. Power on the services gateway by pressing the Power button on the front panel of the SFB for three to five seconds. Wait for the services gateway to start.
  15. Verify that the SFB is functioning normally by checking the LEDs on its faceplate. The SFB STATUS LED should light steadily green a few minutes after the services gateway is powered on. If the SFB STATUS LED is red, remove and install the SFB again. If the SFB STATUS LED still lights steadily red, the SFB is not functioning properly. Contact your customer support representative.
