Introduction
CTS’s Managed Switch is designed to meet the emerging FTTX & Metro Ethernet requirements. Its
low profile appearance with 1U height and the standard rack-mounted size achieve the highest
density within a single rack. When massive fiber ports need to be deployed, the Managed Switch
provides the best performance and price ratio.
1.1 Overview of EPS-3128
EPS-3128, a 19-inch and rack mountable Managed PoE Ethernet Switch, has 24 10/100/1000BaseT up to 30W PoE ports + 4 combo uplink ports (10/100/1000Base-T and 100/1000Base-X SFP) in
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 solution to Metro Ethernet application. Besides, it can be
used as a stand-alone switch. With the height of 1U and the standard-size rack design in
appearance, EPS-3128 can be used in closet wiring as well.
