HP JL357A#ABA 2540 48G PoE+ 4SFP+ 48-Port + 4-Port SFP+ Layer 2 Switch

Description

The HP 2540 48G PoE+ 4SFP+ Switch, identified by the part number JL357A#ABA, is a robust Layer 2 managed network switch designed to provide high-performance connectivity for enterprise environments. It features 48 Gigabit Ethernet ports that support Power over Ethernet Plus (PoE+), allowing it to power devices such as IP phones, wireless access points, and security cameras directly over the network cable. The total PoE budget of 370W provides ample power for a significant number of connected devices. For high-speed uplinks and connections to core network infrastructure or other switches, the JL357A#ABA includes four 10 Gigabit Ethernet SFP+ ports. These ports offer substantial bandwidth for aggregating traffic from the access layer or for connecting to high-capacity network backbones. The switch's Layer 2 capabilities include advanced features such as VLANs, QoS, link aggregation, and robust security protocols like Access Control Lists (ACLs) and port security, enabling administrators to effectively manage and secure the network. This switch is designed for ease of deployment and management, often supporting features like stacking (though specific stacking capabilities may vary by model revision and firmware) for simplified administration of multiple switches as a single logical unit. Its reliability and feature set make it suitable for demanding campus and branch office network deployments where performance, power delivery, and network control are essential.
