Replacing a Network Processing Card on the SRX1400 Services Gateway


The SRX1400 Services Gateway is not normally equipped with a Network Processing Card (NPC). In most configurations, network processing functions are performed by the NSPC. However, replacing the NSPC with an SRX3000-series SPC and an NPC in slots 1 and 3 is a supported configuration for the SRX1400 Services Gateway.

The NPC is installed in the front of the services gateway in CFM slot 3.

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 SRX1400 Services Gateway.
  3. Loosen the captive screws at each end of the NPC faceplate.
  4. Grasp the NPC by its handle and slide it halfway out of the chassis. See Figure 1.

  5. Place one hand underneath the NPC to support it and slide it completely out of the chassis.
  6. Place the NPC on the antistatic mat.
  7. Slide the replacement NPC into the slot until you feel resistance, and then press the NPC's faceplate until it engages the connectors as shown in Figure 2.

  8. Tighten the captive screws on the left and right of the NPC.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.

When you power on the SRX1400 Services Gateway, the OK/FAIL LED on the NPC faceplate blinks green, then lights steadily indicating a normal operating condition.


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.
