SRX3600 Services Gateway SPCs
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 can 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.
