Introduction
This chapter introduces and shows you how to access the EMS (Element Management
System).
1.1 Overview
The Element Management System (EMS) retrieves management information from switches
using SNMP protocol.
An EMS is composed of Network Elements (NE) that represent resources in a Network
Management System (NMS). The network elements can represent a physical piece of
equipment on the network, the components of a device on the network, or parts of the network
itself.
The following figure shows a network example.

1.1.1 EMS Components
The EMS consists of two components: the EMS server and the EMS remote client. You must
install the EMS server, which provides all the functions to use the EMS. You can install the
EMS remote client on other computers if you want to use EMS on them as well.
You can send SNMP messages to managed devices from an EMS remote client (RC) or
through the EMS server (S). The following figure shows a network example.
