Introduction
CTS’s Managed Switch is designed to meet the emerging FTTX & Metro Ethernet requirements.
Besides the low profile appearance with 1U height and the standard 8.5-inch rack-mounted size, the
product also achieves hassle-free monitoring and comprehensive management for any network
operator who desires to build up a reliable telecommunication network infrastructure. When it comes
to FTTX deployment, the Managed Switch provides the best performance and price ratio.
1.1 Overview of ESW-5112-2MG
The product is a 8.5-inch and rack mountable Managed Switch, equipped with 8 Gigabit Ethernet
ports (10/100/1000Base-T), 2 Multi-G Ethernet ports (100M/1G/2.5G/5G/10GBase-T), and 2 SFP+
ports (1/10GBase-R) on the front panel. This Managed Switch provides high performance, store and
forward switching capability plus other advanced features such as QoS, VLAN, Spanning Tree,
LACP and so on.
LED indicators located on the front panel ease the users’ effort to monitor and manage the network
status. The built-in management module also allows users to configure, control and monitor the
system locally via console or remotely via SNMP-based management system.
This Managed Switch is a typical SFP/SFP+ solution to FTTX service implementation. Besides, it
can be used as a stand-alone switch. With the height of 1U and the 8.5-inch standard-size rack
design in appearance, the network switch can be used in closet wiring as well.
