Product Description
The HP J9311A, part of the 3500-48G-PoE+ series, is a high-performance, fully managed Layer 3 switch designed for demanding enterprise network environments. It features 48 auto-sensing Gigabit Ethernet ports, each capable of delivering Power over Ethernet Plus (PoE+), providing up to 30W per port to power devices like IP phones, wireless access points, and surveillance cameras. This switch offers advanced Layer 3 routing capabilities, including support for static and dynamic routing protocols such as RIP (Routing Information Protocol). This allows for more sophisticated network segmentation and traffic management compared to Layer 2 switches. The inclusion of four SFP (Small Form-Factor Pluggable) slots provides flexible and high-speed uplink options to connect to core network infrastructure or other switches. The 3500-48G-PoE+ switch is ideal for use as an access or aggregation layer device in enterprise networks. Its combination of high port density, PoE+ support, Layer 3 routing, and robust management features makes it a versatile and powerful solution for modern network deployments requiring both performance and advanced functionality.
