PPLICATIONS
The Switch 4800G are designed as convergence layer switches or access layer
switches for enterprise networks and MANs. The Switch 4800G provide 24 or 48
autosensing Gigabit Ethernet ports and four SFP Combo Gigabit optical interfaces.
In addition, the Switch 4800G provide two extension slots. You can configure
XFP/CX4 extension module and up to four 10GE ports are supported. Networking
is very flexible. The Switch 4800G can apply to Gigabit Ethernet to the desktop
(GTTD) access of enterprise networks, user access of campus networks, and
connection of data center server clusters. Several typical networking applications
are described as follows.
Serving as a
Convergence Layer
Device
In medium- and large-sized enterprises or campus networks, the the Switch
4800G can serve as convergence layer switches that provide high-performance
and large-capacity switching service and support 10GE uplink interfaces, which
provide larger bandwidth for the devices.

networks/campus networks
Serving as a Access
Layer Device
The Switch 4800G can serve as access layer switches that provide large access
bandwidth and high port density. The Switch 4800G also provide PoE. Through
Ethernet cables, the Switch 4800G can provide power to IP phone, WLAN AP, and
other PD devices that support IEEE 802.3af to facilitate network maintenance and
management.
