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:
Switch 4800G 24-Port. 24 10/100/1000 Mbps ports
with two dual-port 10-Gigabit slots; includes four SFP
Gigabit combo ports
Switch 4800G 48-Port. 48 10/100/1000 Mbps ports
with two dual-port 10-Gigabit slots; includes four SFP
Gigabit combo ports
Switch 4800G PWR 24-Port. 24 10/100/1000 Mbps
PoE ports with two dual-port 10-Gigabit slots;
includes four SFP Gigabit combo ports
Switch 4800G PWR 48-Port. 48 10/100/1000 Mbps
PoE ports with two dual-port 10-Gigabit slots;
includes four SFP Gigabit combo ports
Switch 4800G 24-Port SFP. 24 SFP Gigabit ports with
two dual-port 10-Gigabit slots and dual removable
power supplies, with up to two power-cord inputs;
includes eight 10/100/1000 Mbps combo ports
