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

8
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
gateway 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 services gateway 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 services gateway 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.

Each SPC consists of the following components:
SPC cover, which functions as a ground plane and a stiffener.
Two small form-factor pluggable (SFP) chassis cluster control ports for connecting
multiple devices into a redundant chassis cluster. See Junos OS Security Configuration
Guide for more information about connecting and configuring redundant chassis
clusters.
