Introduction
General Description
Easily boosting your networking throughput, LevelOne GSW-1641 provides you 16
10/100/1000Mbps gigabit ports that lead you to a real gigabit connection. Users are
now able to transfer high bandwidth-demanded files faster and get a real efficiency
improvement with the user-friendly web-based management interface. This product
also equips one mini GBIC slot for your flexible fiber connection. Use of the
mini-GBIC port disables the connection of 16th copper port automatically.
The management functionalities provide efficient network usage. VLAN reduces the
collisions from widely broadcasting. Port aggregation enlarges the bandwidth of
backbone connection. QoS is supported to secure the bandwidth for some
bandwidth-demanded applications including VoIP or videoconference. The 802.3x
and backpressure flow control mechanisms are also supported to ensure the
correctness of data transmitting.

The Rear Panel
The rear panel of the switch:
Port Operation
The auto-negotiation feature allows those ports running at one of the following
operation modes:
Media Speed Duplex Mode
Full Duplex
10Mbps Half Duplex
Full Duplex
100Mbps Half Duplex
10/100/1000Mbps(copper)
1000Mbps Full Duplex
1000Mbps(Fiber)

Note: For the last port, when both the fiber and cooper interfaces are connected, the
system adapts the fiber interface and disables the relevant cooper port automatically.
Reset Button
You can use this button to reset the switch or restore factory default settings. To reset
the switch, press the button once.
To restore factory default settings, press and hold the button for three seconds.
Power Receptacle
To be compatible with the electric service standards around the world, the switch is
designed to afford the power supply in the range from100 to 240VAC, 50/60Hz.
Please make sure that your outlet standard to be within this range.
To power on the switch, please plug the female end of the power cord firmly into the
receptacle of the switch and the other end into an electric service outlet. After the
power cord installation, please check if the power LED is lit for a normal power status.

Installation
This switch can be placed on your desktop directly, or mounted in a rack. Please refer
to the instructions for installation.
Before installing the switch, we recommend:
1. The switch is placed with appropriate ventilation environment. A minimum 25mm
space around the unit is recommended.
2. The switch and the relevant components are away from sources of electrical
noise such as radios, transmitters and broadband amplifiers.
3. The switch is away from environments beyond recommend moisture.
Desktop Installation
1. Install the switch on a level surface that can support the weight of the unit and
the relevant components.
2. Plug the switch with the female end of the provided power cord and plug the
male end to the power outlet.
Rack-mount Installation
The switch may be standalone, or mounted in a rack. Rack mounting facilitate to an
orderly installation when you are going to install series of networking devices.
Procedures to rack-mount the switch:
1. Disconnect all the cables from the switch before continuing.
2. Place the unit the right way up on a hard, flat surface with the front facing you.
3. Locate a mounting bracket over the mounting holes on one side of the unit.
4. Insert the screws and fully tighten with a suitable screwdriver.
5. Repeat the two previous steps for the other side of the unit.
6. Insert the unit into the rack and secure with suitable screws (optional).
7. Reconnect all the cables.

Installing Network Cables
1. Crossover or straight-through cable: All the ports on the switch support
auto-MDI/MDI-X functionality. Both straight-through or crossover cables can be
used as the media to connect the switch with PCs as well as other devices like
switches, hubs or router.
2. Category 3,4,5 or 5eUTP/STP cable: To make a valid connection and obtain the
optimal performance. An appropriate cable that corresponds to different
transmitting/receiving speed is required. To choose a suitable cable, please refer
to the following table.
Media Speed Wiring
10Mbps Category 3,4,5 UTP/STP
100Mbps Category 5 UTP/STP
10/100/1000Mbps
copper 1000Mbps Category 5,5e UTP/STP
1000Mbps Fiber
(Mini GBIC required) 1000Mbps
The cable type differs from the
mini-GBIC you choose. Please refer to
the instruction came with your
mini-GBIC.
Network Application

10
Functional Description
Jumbo Frame
With Jumbo Frame supported, it is allowed for the switch to transport identical data in
fewer frames. Hence helps to ensure fewer overheads, shorten processing time, and
reduce interrupts.
Note: To enable Jumbo Frame, Flow Control should be enabled in advance.
Flow Control and Back Pressure
Flow control and Back Pressure both contributes for lower and higher speed devices
to communicate to each other hence ensures the correctness of data transmitting.
The 802.3x Flow Control and Back Pressure mechanisms work respectively for full
and half duplex modes. Flow control can be enabled or disabled on a per-port basis.
Mirror
The Mirror function provides network administrator to monitor the traffic. By
forwarding a copy of the packets that received or transferred by the monitored port,
the sniffer port received all the packets and hence is able to monitor the traffic of the
specified port.
VLAN
With VLAN supported, the network can be segmented in groups to reduce the
collisions from widely broadcasting. The device supports both port-based VLAN and
802.1Q tag-based VLAN. Port-based VLAN classifies incoming packets to VLANs
according to their ingress port. The 802.1Q based VLAN add a tag to the header of
the packet to classify their VLANs.
Trunk (Aggregation)
The Trunk functionality integrates several ports to enlarge the bandwidth that helps to
boost the backbone connectivity. The switch allows the Maximum 8 group and 8
members for each group.
Quality of Service (QoS)
The QoS service classifies packets into different precedence. The packets are
transmitted and received by their classified priorities. This mechanism helps high
bandwidth demanded applications such as VoIP to get an unobstructed connection.
SNMP
This device is SNMP(Simple Network Management Protocol)-management
supported. This allows this product to be monitored or inspected by a SNMP
management station.
