Aruba 2540 24G PoE+ 4SFP+ Switch

The Aruba JL356A is a network access switch that combines gigabit connectivity, generous PoE power, and straightforward management in a 1U enclosure. With twenty-four PoE+ Ethernet ports, it supplies both data and up to 370 W of power to devices such as IP cameras, VoIP phones, or wireless access points, letting you place equipment exactly where it is needed without separate power injectors.

Four SFP+ slots accept 1 GbE or 10 GbE transceivers, so you can link the switch to a core network or server stack at high speed and expand bandwidth as your traffic grows. A switching capacity of 128 Gbps and a forwarding rate of 95.2 million packets per second are driven by a dual-core ARM Cortex A9 processor running at 1016 MHz, supported by 1 GB of DDR3 SDRAM and 4 GB of eMMC flash. This hardware mix keeps voice, video, and data streams moving smoothly even during peak hours.

The enclosure can sit on a shelf, slide into a standard 19-inch rack, or mount on a wall, giving installers flexibility in small offices, branch locations, classrooms, or retail settings. Management is available through a browser, command line, or secure protocols such as SSL, SSH2, RADIUS, and TACACS+. A MAC address table that holds 16,384 entries helps administrators keep track of connected devices as the network expands.
