SRX3600 Services Gateway CFMs
The services gateway chassis supports common form-factor modules (CFMs). A single-wide module format
and a double-wide module format are available. I/O card (IOC), Services Processing Card (SPC), and Network
Processing Card (NPC) modules are in single-wide CFM format. The Switch Fabric Board (SFB), Routing
Engine, and SRX Clustering Module (SCM) are not in CFM format, and thus have assigned slots within the
chassis. With the interchangeability among the IOCs, SPCs, and NPCs, you have more flexibility and
scalability when deploying your networks based on the requirements in the field. For example, if you need
more ports and bigger oversubscription ratio, then you can load more slots with IOCs; on the other hand,
if you need smaller oversubscription ratio for better QoS behavior, or you need more security services,
then you can load more slots with SPCs and only use the on-board network interface ports.

SRX3600 Services Gateway Switch Fabric Board
The Switch Fabric Board (SFB) is the data plane for the subsystems in the chassis. The SFB performs the
following functions:
•
Powers the services gateway on and off
•
Controls clocking and distribution
•
Provides eight copper Gigabit Ethernet ports and four fiber Gigabit Ethernet ports
•
Provides two high availability (HA) Control ports
•
Provides interconnections to all the IOCs within the chassis through integrated switch fabrics
