Aruba 253 48 Rack Mountable 48 Ports Managed Switch

The Aruba J9781A#ABA is a 48 port Ethernet switch that delivers full Layer 2 management without weighing down your budget or your rack. With forty-eight 10/100 ports, it can link a dense mix of desktop computers, printers, access points, or IoT devices, which makes it an easy fit for a busy small office, a classroom lab, or the edge of a larger campus network.

Four dedicated uplink connections keep traffic flowing smoothly toward the core. Two Gigabit RJ-45 ports handle high speed copper links, while two SFP cages accept fiber transceivers for longer runs to another closet or building. An 800 MHz ARM processor works with 256 MB of RAM and 128 MB of flash memory to drive a feature set that includes VLANs for segmentation, ACLs for access control, QoS for voice and video prioritization, and sFlow for detailed traffic visibility. The switch forwards up to 13 million packets per second across a 17.6 Gbps switching fabric, which is more than enough capacity for typical edge traffic.

Energy Efficient Ethernet helps trim power consumption during quiet periods, and models in the same series can provide PoE+ if you later need to power phones or cameras. Installation is flexible: mount it in a standard 19 inch rack, attach it to a wall, or place it on a shelf or desktop. Once in place, the ArubaOS interface and familiar command-line options make everyday management straightforward for any administrator who has worked with managed switches before.
