SRX5800 Services Gateway Services Processing Card Description

Each Services Processing Card (SPC) contains two Services Processing Units (SPUs), which provide the processing power to run integrated services such as firewall, IPsec, and IDP (see Figure 8). All traffic traversing the services gateway is passed to an SPU to have services processing applied to it. Traffic is intelligently distributed by IOCs to SPUs for service processing.

The services gateway must have at least one SPC installed. You can install additional SPCs to increase services processing throughput.

You can install SPCs in any of the slots not reserved for SCBs. 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.

Figure 8 shows a typical SPC supported on the services gateway.
