The HP E5400 Series consists of the most advanced intelligent switches in the HP E Series product line. The E5400 series includes 6-slot and 12-slot chassis and associated zl modules and bundles. The foundation for all of 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 10/100, Gigabit and 10-Gigabit interfaces, integrated PoE+ on 10/100 and 10/100/1000Base-T ports, and a choice of form factors, the E5400 switches offer excellent investment protection, flexibility, and scalability, as well as ease of deployment, operation, and maintenance.
