Overview: The HP E4800G Switch Series is a Gigabit switch family that delivers outstanding security reliability and multi-service support capabilities for robust switching at the edge or aggregation layer of large enterprise and campus networks or in the core layer of medium- and small-sized enterprise networks. The family consists of Layer 2/3/4 Gigabit Ethernet switches that can accommodate the most demanding applications providing resilient and secure connectivity and the latest traffic-prioritization technologies to optimize applications on converged networks. Designed for maximum flexibility these switches are available with 24 or 48 Gigabit ports. Power over Ethernet (PoE) and non-PoE models are offered with optional 10 Gigabit expansion capability and small form-factor pluggable (SFP) mini-GBIC Gigabit combo ports for fiber flexibility. The all-SFP model with dual power supplies for highest availability applications allows for very flexible fiber with copper Gigabit connectivity.
