Product Overview

The Juniper SRX345 Services Gateway with Dual AC Power (SRX345-SYS-JB-2AC) is the dual power supply variant of the SRX345, designed for midsize to large enterprise branch offices requiring high availability. With redundant AC power supplies, it ensures continuous operation even if one power supply fails.

This model delivers the same performance as the standard SRX345: up to 5 Gbps firewall performance, 800 Mbps IPsec VPN throughput, and 375,000 concurrent sessions. It features 16x 1GbE MACsec-capable ports, 4x Mini-PIM slots, and 2,048 IPsec VPN tunnels.

The dual AC configuration makes this model ideal for mission-critical branch office deployments where power redundancy is essential for maintaining continuous security and network services.
