The SRX 5600 services gateway is a high-performance, highly-scalable, carrier-class
security device with multi-processor architecture.
The SRX 5600 services gateway is eight rack units (RU) tall. Three of these devices
can be stacked in a single floor-to-ceiling rack, for increased port density per unit of
floor space. The device provides 8 slots that can be populated with up to 6 Services
Processing Cards (SPCs) and I/O cards (IOCs) and two Switch Control Boards (SCBs)
in nonredundant fabric configurations.
Fully populated, the SRX 5600 provides up to 200 Gigabit Ethernet or up to 20
10-Gigabit Ethernet ports. Two types of IOCs are available, both of which consist of
four Packet Forwarding Engines and support a throughput of 40 Gbps:
A 40-port Gigabit Ethernet IOC with SFP connectors (1000 Mbit copper and fiber
only).
A 4-port 10–Gigabit Ethernet IOC with XFP connectors.
The SRX 5600 chassis provides redundancy and resiliency. The hardware system is
fully redundant, including power supplies, fan trays, and Switch Control Boards.
The Packet Forwarding Engines combined with the Ethernet ports on an IOC plug
into the chassis. IOCs are connected to (redundant) Switch Control Boards (SCBs).
The connections between IOCs and SCBs are organized in three groups:
The fabric connects the IOCs and provides for packet transport between IOCs
and SPCs. Two SCBs are needed for non-redundant fabric configuration.
Gigabit Ethernet. The control plane of the chassis consists of Gigabit Ethernet
links between Switch Control Boards/Routing Engines and each IOC and SPC.
All board-to-board information is passed over Ethernet except for low-level status
and commands.
