The HP E3500 Switch Series consists of the most advanced intelligent edge switches in the HP Networking product line. The E3500 series includes 24-port and 48-port fixed-port switches. The foundation for all these switches is a purpose-built, programmable ProVision ASIC that allows the most demanding networking features, such as Quality of Service (QoS) and security, to be implemented in a scalable yet granular fashion. With a variety of Gigabit and 10/100 interfaces; integrated PoE+, PoE, and non-PoE options; and versatile 10-GbE connectivity (CX4, X2, and SFP+) on Gigabit switches, the E3500 switches offer excellent investment protection, flexibility, and scalability, as well as ease of deployment, operation, and maintenance.
