SRX345 Services Gateway Description
The SRX345 Services Gateway consolidates security, routing, switching, and WAN
interfaces for midsize distributed enterprises. With advanced threat mitigation capabilities,
the services gateway provides cost-effective and secure connectivity across distributed
enterprises. The services gateway simplifies network complexity, protects and prioritizes
network resources, and improves user and application experience.
The SRX345 Services Gateway has a capacity of 5 gigabits per second (Gbps) and is 1
rack unit (U) tall. The services gateway has eight 1 G Ethernet ports, eight 1 G SFP ports,
one management port, 4 GB of DRAM memory, 8 GB of flash memory, and four
Mini-Physical Interface Module (Mini-PIM) slots. The chassis installs in standard 800–mm
(or larger) enclosed cabinets, 19 in. equipment racks, or telecommunications open-frame
racks.
