24 CHAPTER : NETWORKING APPLICATIONS
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.
