SRX3600 Services Gateway Description
The SRX3600 Services Gateway is a high-performance, scalable, carrier-class security device with
multi-processor architecture. The SRX3600 Services Gateway has a capacity of up to 30 gigabits per
second (Gbps) in full duplex and is five rack units (U) tall. Nine services gateways can be stacked in a single
floor-to-ceiling rack for increased port density per unit of floor space. The SRX3600 Services Gateway
provides 12 common form-factor module (CFM) slots that can be populated with up to seven Services
Processing Cards (SPCs), up to three Network Processing Cards (NPCs), up to six I/O cards (IOCs), and up
to eleven Network Processing I/O cards (NP-IOCs). The services gateway also has one dedicated slot for
the Switch Fabric Board (SFB), one slot for a Routing Engine, one slot for an SRX Clustering Module (SCM),
four slots for power supplies, and one slot for the fan tray and air filter.
