SPCs for the SRX1400 Services Gateway

 

Services Processing Cards (SPCs) are common form-factor module (CFM) cards that provide processing power to run integrated services such as firewall, IPsec, and IDP. All traffic traversing the services gateway is passed to an SPC to have services processing applied to it. Traffic is intelligently distributed by Network Processing Cards (NPCs) to SPCs for services processing, including session setup based on policies, fast packet processing for packets that match a session, encryption and decryption, and IKE negotiation.

There are two places where you can install an SPC in your SRX1400 Services Gateway:

  • You can install an SPC in the front-panel slot labeled 1 if you also install an NPC in the slot labeled 3. This combination of SPC and NPC replaces the full-width Network and Services Processing (NSPC) card that is normally installed in the SRX1400 Services Gateway to perform both services processing and network processing functions.

  • If your SRX1400 Services Gateway is running Junos OS Release 12.1X44-D10 or later, you can install an SPC in the slot labeled 2. Doing so increases the services processing performance of the services gateway and increases its session capacity.

Note
  • If a CFM 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.
