Description
The Juniper EX3400-48P-3S-E is a versatile managed Ethernet switch designed for enterprise network access layers. It features 48 ports of 10/100/1000BASE-T Gigabit Ethernet, all supporting IEEE 802.3at Power over Ethernet Plus (PoE+), enabling it to power connected devices like IP phones, wireless access points, and security cameras with up to 30W per port. This model includes four 1GbE SFP (Small Form-Factor Pluggable) ports for uplink connectivity. These ports provide flexible options for connecting to higher-tier switches or network segments using either copper or fiber optic transceivers, though they operate at 1Gbps speeds, unlike the 10Gbps SFP+ ports on other EX3400 models. The switch offers a total switching capacity of 176 Gbps and a forwarding rate of 131 Mpps, ensuring efficient traffic management. Running on Juniper's robust Junos OS, the EX3400-48P-3S-E supports advanced Layer 2 and Layer 3 features, including Virtual Chassis technology for simplified management of multiple switches as a single entity. The '-3S-E' designation typically refers to a specific power supply and fan configuration, often optimized for standard enterprise environments.
