SRX3600 Services Gateway Services Processing Cards
Services Processing Cards (SPCs) are common form-factor module (CFM) cards that provide the 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 service processing applied to it. Traffic is intelligently distributed by Network Processing Cards (NPCs) to SPCs for service processing, including session setup based on policies, fast packet processing for packets that match a session, encryption and decryption, and IKE negotiation.
The services gateway must have at least one SPC installed. You may install additional SPCs to increase services processing throughput.
 | 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 services gateway. |
