SW3
GIGABIT/FAST ETHERNET SWITCH TYPE SW3 (DIN) 6/122
USER GUIDE - M0SW3D1905Iv04 - V04 May 2019
1 INTRODUCTION
1.1 GENERAL
The SW3 is a Gigabit/Fast Ethernet switch intended for big scale LAN deployments where:
port density,
switching performance, and
logical complexity
are the main challenges to surpass.
SW3 devices bring the necessary capabilities to implement the automation of electrical
substations according to the IEC 61850 standard.
The SW3 can be managed locally and remotely, through a local console, Telnet server and
SSH server, or through a built-in web server, HTTP or HTTPS.
The SW3 also supports the SNMPv1, SNMPv2c and SNMPv3 protocols, as well as other
protocols and services such as LLDP, GARP/GMRP, NTP/SNTP, TACACS+ and RADIUS.
1.2 MAIN CHARACTERISTICS
Some of the SW3 most important features are described below.
❖ Grouping of services and architectures.
Services may be grouped and discriminated, some not being accessible with others,
through the configuration of different VLANs.
Each VLAN is different from the others thanks to a specific identifier, called VID, which
is included in the VLAN tag and specified in the standard IEEE 802.1q. It permits
several VLANs to share resources, either switching devices such as the SW3, or links
between switching units, guaranteeing that each VLAN traffic will remain isolated from
the others.
The standard 802.1q admits three types of frames: untagged frames, tagged frames
with the VLAN (VID) identifier and the priority (tagged) or only the priority (priority
tagged, VLAN = 0).
The SW3 may adapt to different network architectures, such as: star, double star, ring,
double ring, and linked rings.
