SRX3400 Services Gateway Description
The SRX3400 Services Gateway is a high-performance, scalable, carrier-class security
device with multi-processor architecture. The services gateway has a capacity of up to
20 gigabits per second (Gbps) in full duplex and is three rack units (U) tall. Sixteen
services gateways can be stacked in a single floor-to-ceiling rack, for increased port
density per unit of floor space. The services gateway provides seven common form-factor
module (CFM) slots that can be populated with up to four Services Processing Cards
(SPCs), up to two Network Processing Cards (NPCs), up to four I/O cards (IOCs), and
up to six 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), two slots for power supplies, and one slot for the
fan tray and air filter.
