Replacing a Network Processing Card on the SRX3400 Services Gateway

The Network Processing Card (NPC) is installed in the rear of the services gateway in slot 5, 6, or 7. Before you replace an NPC, you must power off the services gateway.

To replace an NPC:

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  2. 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.
  3. If you have not already done so, power off the services gateway by pressing the Power button on the front panel of the Switch Fabric Board (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 proceeding.

  4. Loosen the captive screws at each end of the NPC faceplate.
  5. Grasp the NPC by its handle and slide it halfway out of the chassis.
  6. Place one hand underneath the NPC to support it and slide it completely out of the chassis.
  7. Place the NPC on the antistatic mat.

  8. Slide the replacement NPC into the slot until you feel resistance, and then press the NPC's faceplate until it engages the connectors.
  9. Tighten the captive screws on the left and right of the NPC.

  10. Power on the services gateway, as described in Powering On the SRX3400 Services Gateway. The OK/FAIL LED on the NPC faceplate should blink green, then light steadily.

    Note: If the OK/FAIL LED is red, remove and reinstall the NPC. If the OK/FAIL LED remains red, the NPC is not functioning properly. Contact your customer support representative.

    Warning: Never lift the services gateway using the handles on the front panels of the NPCs or other CFM cards. The handles might come off, causing the chassis to drop and inflicting possible grave injury.
