Hewlett Packard Enterprise JL357A Network Switch

The Hewlett Packard Enterprise JL357A Aruba 2540-48G PoE switch is a 48-port PoE-enabled Gigabit Ethernet switch with four SFP uplink ports, engineered for dense campus edge deployments where power and data need to travel over the same cable to simplify cabling and management. It powers PoE devices such as IP phones, wireless access points, and other compatible endpoints directly from its ports, reducing the need for separate power injectors and enabling centralized, easy-to-manage device placement in meeting rooms, hallways, and workgroups. The four SFP uplink ports provide flexible options for fiber-based aggregation up to distribution or core layers, supporting scalable growth as network needs evolve in office buildings, retail environments, or small campuses without swapping hardware. As part of the Aruba 2540 family, this model emphasizes reliable performance at the access layer and is designed for straightforward deployment in mid-size networks, offering a practical balance of features, price, and power efficiency for modern enterprise networks.
