OVERVIEW
The 3Com® Switch 4800G Gigabit Family 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
is comprised 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
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.

Multiple Switch 4800G units can be stacked together, up to nine units high, using patented 3Com
eXpandable Resilient Networking (XRN®) technology. With XRN, it is easy to build fully redundant
networks, with aggregated ports spread across multiple units, with all units presenting
themselves with a single simplified management interface.

Each of the five 3Com Switch 4800G models comes in a convenient, stackable 1U-high enclosure:
