Services Processing Card SRX5K-SPC-4-15-320 Specifications

The SRX5K-SPC-4-15-320 Services Processing Card (SPC) contains four Services Processing Units
(SPUs), which provide the processing power to run integrated services such as firewall, IPsec, and IDP
(see Figure 4 on page 15). All traffic traversing the firewall is passed to an SPU to have services
processing applied to it. Traffic is intelligently distributed by I/O cards (IOCs) to SPUs for services
processing.
The firewall must have at least one SPC installed. You can install additional SPCs to increase services
processing capacity.
You can install SPCs in any of the slots that are not reserved for Switch Control Boards (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.
If your firewall contains a mix of SRX5K-SPC-4-15-320 SPCs and earlier SRX5K-SPC-2-10-40 SPCs, an
SRX5K-SPC-4-15-320 SPC must occupy the lowest-numbered slot of any SPC in the chassis. This
configuration ensures that the center point (CP) function is performed by the faster and higher-
performance SPC type.
