CHAPTER 1
Getting to Know Your Switch
This chapter introduces the main features and applications of the switch.
1.1  Introduction 
The ES-4124 is a stand-alone layer 3 Ethernet switch with 24 10/100Mbps ports, two RJ-45 
Gigabit ports for stacking and 2 GbE dual personality interfaces for uplink as well as a console 
port and a management port for local management. A dual personality interface includes one 
Gigabit port and one slot for a mini-GBIC transceiver (SFP module) with one port active at a 
time. 
With its built-in web configurator, managing and configuring the switch is easy. In addition, 
the switch can also be managed via Telnet, any terminal emulator program on the console port, 
or third-party SNMP management.
See Appendix A on page 281 for a full list of software features available on the switch.
1.1.1  Backbone Application 
The switch is an ideal solution for small networks where rapid growth can be expected in the 
near future. The switch can be used standalone for a group of heavy traffic users. You can 
connect computers and servers directly to the switch’s port or connect other switches to the 
switch. 
In this example, all computers can share high-speed applications on the server. To expand the 
network, simply add more networking devices such as switches, routers, computers, print 
servers etc.
