PRODUCT OVERVIEW
Introduction 3Com Switch 4800G Family (hereinafter referred to as the Switch 4800G) are
Gigabit Ethernet switching products developed by Hangzhou 3Com Technologies
Co., Ltd. (hereinafter referred to as 3Com). The Switch 4800G support diversified
service features, IPv6 forwarding, and routing function, and provide 10GE
extended module slots. Through the 3Com proprietary cluster management, you
can streamline network management. The Switch 4800G are designed to operate
at the convergence or access layer of enterprise networks and metropolitan area
networks (MANs). The Switch 4800G support the IPv4/IPv6 dual stack and can also
be used for connecting server groups in data centers.
Table 2 lists the models of the Switch 4800G.
Together with an auto-sensing 10/100/1000BASE-T Ethernet port, each
1000Base-X SFP port forms a Combo port. For each Combo port, either the SFP
port or the auto-sensing 10/100/1000BASE-T Ethernet port can be used at a time.
For the mapping between the two ports forming a Combo port, refer to Table 3.

Power System The Switch 4800G 48-Port can adopt two hot-swappable AC or DC power
modules to provide backup.
AC power input
Rated voltage range: 100 VAC to 240 VAC, 50 Hz or 60 Hz
Input voltage range: 90 VAC to 264 VAC, 47 Hz to 63 Hz
DC power input
Rated voltage range: -48 VDC to -60 VDC
Input voltage range: -36 VDC to -72 VDC
Cooling System The Switch 4800G 48-Port is equipped with six fans (four for the system, and one
for each power module) for heat dissipation.
