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 ports
10/100/1000Base-T RJ-45 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 capability 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 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
Managed Switch RJ-45 port directly via RS-232 cable 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.
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.

9
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.

CAUTION
To prevent any damage or failure of the Managed Switch, please DO
NOT block the ventilation FAN holes.
Use the following guidelines when choosing a place to install the Switch:
Firm and steady flat surface.
Proper power outlet location, not too far from the device.
Visually inspect the power cord and see that it is secured to the AC
power connector.
Make sure that there is proper heat dissipation from and adequate
ventilation around the switch. Do not place heavy objects on the
Managed Switch.
Desktop Installation
The switch can be placed in any flat and steady surface with proper air
ventilation. Four rubber feet with adhesive backing are provided for installation.
Procedure
1. Attach rubber feet on the bottom at each corner of the device.
2. Select a flat and steady surface and place the switch.
3. Allow adequate space for ventilation between the device and the
objects around it.
Rack Installation
WARNING!
Please mount the Switch firmly in rack otherwise it may be fall and
cause the system damage and possible injury to personnel.

12
The Managed Switch can be mounted in an EIA standard-sized, 19-inch rack,
which can be placed in a wiring closet with other equipment. Rack mounting
brackets are provided to mount the Switch.
Procedure
1. Plan the rack position.
2. Attach the mounting bracket on the switch’s side panels (one on each
side) and secure them with the screws provided.
3. Align the Switch with mounting bracket into the selected mounting rail
position.
4. Then, use the screws provided with the equipment rack to mount the
switch into the selected mounting rails position carefully and firmly.
5. Please ensure that the ventilation holes are not blocked.
2.4 Power ON
The Managed Switch can be used with AC power supply 100-240 VAC, 50 –60
Hz or DC power supply 48V. The power switch is located at the rear of the unit
adjacent to the power connector.
After the Managed Switch is turned on, the Power LED indicators should light in
green and the FAN should spin.

13
Power Failure
In the event of power failure, unplug the power that is plugged into the switch at
the back of the device. When power is resumed, plug the power back to the
switch.

14

Connect to Network
The Managed Switch has 24 RJ-45 and 4 combo ports in front panel. These 24
RJ-45 ports can be plugged with 10/100/1000Base-T UTP connector. 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.
