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 negotation.

The services gateway must have at least one SPC installed. You may install additional SPCs to increase services processing throughput. You can install SPCs in any CFM slot, but we recommend that you install SPCs in rear panel slots to leave room for IOCs in the front panel slots.

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.

Table 1 describes the SPC behavior indicated by the LEDs on its front panel. To power up or power down an SPC, you must use the main Power button on the front of the Switch Fabric Board (SFB). The ONLINE button does not perform any function.
