Installing a Network Processing Card

Table 2 shows the NPC and slot support for the SRX 3400 and SRX 3600 services gateways.

Table 2: NPC Support


Number of NPCs supported

NPC Slots

SRX 3400


Rear panel slots 5, 6, and 7

SRX 3600


Rear panel slots 10, 11, and 12

Note: If a slot is not occupied by a card, you must install a blank panel to shield the empty slot and to allow cooling air to circulate properly through the device.

To install an NPC:

  1. Attach an electrostatic discharge (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.
  2. If you have not already done so, power off the device 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 device is shutting down. Wait for the device to shut down before proceeding.

  3. Place the card on an antistatic mat or remove it from its electrostatic bag.
  4. Identify the slot on the services gateway where you will install the NPC. See Table 2 for more information about slots and supported modules.
  5. If necessary, remove the blank cover from the slot by loosening its screws and sliding it out of the slot.
  6. Orient the NPC so that the faceplate faces you. Slide the NPC all the way into the card cage until you feel resistance.
  7. Tighten the screws on either side of the card.

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.
