SRX5400 Services Gateway Services Processing Card Overview
The Services Processing Card (SPC) has Services Processing Units (SPUs), which provide the processing
power to run integrated services such as firewall, IPsec, and IDP (see Figure 31 on page 90). All traffic
traversing the services gateway is passed to an SPU to have services processing applied to it. Traffic is
intelligently distributed by interface cards to SPUs for services processing.
The services gateway must have one SPC installed.
You can install an SPC in any of the slots that are not reserved for Switch Control Board (SCB). 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 31 on page 90 shows a typical SPC supported on the services gateway.
