1. INTRODUCTION
The Managed Switch is designed to meet the emerging FTTX & Metro Ethernet
requirement. Its low profile appearance with 1U height and standard rack-
mount size achieves 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 The Managed Switch
This Managed Switch is compact 19-inch, rack mountable, has 24 PoE+
10/100/1000BASE-T RJ-45 ports with 4 combo ports (10/100/1000Base-T,
100/1000Base-X SFP) in front panel. This Managed Switch provides high
performance store and forward switching plus other advanced features such as
QoS, VLAN, etc.
Clear, at-a-glance per-port LED indicators make users easier to control and
manage network status. 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 suit for the SFP to Metro Ethernet application.
Its low profile appearance with 1U height achieves the highest density and can
be used in closet wiring or used as a desktop switch.

1.5 Network Management
This Managed Switch is Plug & Play compliant. Real-time operational status
can be monitored through a set of LED indicators located in the front panel.
Built-in management module also allows users to configure, control and monitor
the system remotely.
Following is a list of management options available in this Managed Switch:
Local Console Management
Telnet Management
SNMP Management
Web Management
Local Console Management
Users may connect a Terminal or PC with Terminal Emulation program, to the
Manage---to configure,
control and monitor the system. This is often referred as Out-Of-Band
management.
Console management is useful when there is no network connection to the
Switch, for instance configuring the Managed Switch for the first time.

10
Telnet Management
Telnet is done through the network. Once there is a network connection to the
Managed Switch, users can use Telnet to configure, control and monitor the
system. Using network connection to manage is often referred to In-Band-
Management.
SNMP Management
SNMP is also In-Band-Management and requires a network connection to the
Managed Switch. The Managed Switch private Management Information Bases
(MIB) is provided for SNMP-based network management program to configure,
control and monitor the system.
Web Management
Web Management is done over the network. Once the Managed Switch is
available on the network, you can login and monitor the status of it through a
web browser remotely or locally. Local console-type Web management,
especially for the first time use of the Managed Switch to set up the needed IP,
can also be done through one of the 10/100/1000Base-T 8-pin RJ-45 ports
located on the front panel of the Managed Switch. Direct RJ-45 LAN cable
connection between a PC and the Managed Switch is required for this
management.
Please refer to the Network Management Users Manual for the detailed
management functions and required installation and operation procedures.

be plugged with 155Mbps. Uplink combo ports 25-28 can be plugged with
155Mbps, 1.25Gbps SFP Fiber transceiver or 10/100/1000BASE-T UTP
connector. The connection of the fiber port must be matched, i.e. Transmitter to
Receiver and vice versa.
