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.\u003c\/p\u003e\u003c\/div\u003e","brand":"HP","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46261974204650,"sku":null,"price":435.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-050.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/hewlett-packard-enterprise-jl357a-network-switch","provider":"GTG Hardware","version":"1.0","type":"link"}
