Mini-GBIC (SFP) Combo slot. Before you start, please verify that your package
contains the following items:

4. User Manual CD
Introduction
General Description
This Switch will instantly boost your networking throughput because it provides
you with 8 Gigabit ports that enable true Gigabit connectivity. Users are now
able to transfer large and bandwidth-hungry files faster and hence get a real
efficiency improvement. This efficiency is further enhanced by the user-friendly
Web-based management interface. In addition to the 8 copper ports, the
Switch offers 1 fiber port that can be used in the place of the nr. 8 copper
port (these are interchangeable or ‘combo’ ports). This mini-GBIC slot
offers the option of a long-distance, fiber-based connection. Use of the
mini-GBIC port automatically disables its corresponding copper port.

The management functions enable efficient network usage. VLAN reduces the
collisions caused by broadcasting. Port Aggregation enlarges the bandwidth of
the backbone connection. QoS secures the bandwidth for some
bandwidth-hungry applications like VoIP and video conferencing. The Switch
also supports 802.3x and backpressure flow control mechanisms to ensure
the correctness of data transmission.

The Rear Panel
The rear panel features all 8 the ports, the 1 SFP slot, the power receptacle and the restore
button:
Port Operation
The auto-negotiation feature allows ports to run in one of the following operation
modes:
Media Speed Duplex Mode
Full Duplex10Mbps Half Duplex
Full Duplex100Mbps Half Duplex
10/100/1000Mbps(copper)
1000Mbps Full Duplex
1000Mbps(Fiber)
(mini GBIC required) 1000Mbps Full Duplex
Note: For the interchangeable (combo) ports (the last RJ-45 ports and the fiber slot),
if both the fiber and copper interfaces of the interchangeable pair (combo) are
connected (incorrect set-up), the system automatically accepts the fiber interface and
disables the copper port.
Restore Default Button
You can use this button to reset the switch or restore it to its 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 electricity standards around the world, the Switch is designed

Attention：The mini-GBIC (SFP) slot shares its LED indicators with its
interchangeable Gigabit RJ-45 (copper) combo port (the last copper
port). Use of the mini-GBIC slot automatically disables this
corresponding copper port.
to work with voltages between 100 and 240V AC and 50/60Hz. Please make sure that
your region’s electricity supply is 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 (male) end into an electricity outlet (usually a
wall plug). After plugging in the power cord, check if the power LED is lit to indicate
normal power status.
Installation
This Switch can be placed on your desktop or mounted in a rack. Installation is very
easy. Users can use all the features of the Switch by simply attaching the cables and
turning the power on.
Before installing the Switch, we strongly recommend that …
1. … the Switch must be placed in an environment that is well ventilated – a
minimum space around the unit of 25mm is recommended.
2. … the Switch and relevant components are far from sources of electrical noise,
such as radios, transmitters and broadband amplifiers
3. … the Switch’s environment is protected from high levels of humidity.
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’s power cord into the power outlet.
Rack Installation
Rack mounting enables orderly installation in cases where many networking devices
have to be installed in the same area. The Switch is supplied with brackets and screws
for rack-mounting purposes.
1. Disconnect all cables from the Switch before mounting it.
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 tighten them with a suitable screwdriver.
5. Repeat this for the other side of the unit.
6. Slide the unit into the rack and secure it with suitable screws.
7. Reconnect all the cables.
Installing Network Cables
8
1. Crossover or straight-through cable: All the ports on the Switch support
Auto-MDI/MDI-X functionality. Both straight-through and crossover cables can
be used to connect the Switch with PCs and other devices like switches, hubs
or router.
2. Category 3,4,5 or 5eUTP/STP cable: To make a valid connection and obtain
optimal performance, it is vital to use the appropriate cables that correspond to
the different transmitting/receiving speeds. 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 according to the
mini-GBIC you choose. Please refer to the
instructions that came with your mini-GBIC

Description of Switch Functions
Jumbo Frame
The Switch supports Jumbo Frames, which means that it can transmit the same data
in fewer frames. This helps to ensure fewer overheads, shorter processing time, and
fewer interruptions.
NOTE: To enable Jumbo Frame, Flow Control should be enabled in advance.
Flow Control and Backpressure
Flow Control and Backpressure both help devices with different processing speeds to
communicate with each other. This ensures the correctness of data transmissions.
The 802.3x Flow Control and Backpressure 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 enables network administrators to monitor all traffic. By forwarding
a copy of the packets that are transferred by the monitored port, the sniffer port
receives all the packets and hence is able to monitor the traffic through the specified
port.
VLAN
This Switch supports Virtual LAN, which means the network can be segmented into
groups to reduce collisions caused by wide broadcasting. The Switch supports both
port-based VLAN and 802.1q tag-based VLAN. Port-based VLAN directs incoming
packets to VLANs according to their ingress ports. 802.1q-based VLAN adds a tag to
the header of the packet to direct the packet to the right VLAN.
Trunk (Aggregation)
The Trunk function groups several ports into one combined transmission channel.
This increases the bandwidth, which helps to boost backbone connectivity. The
Switch allows a maximum of 4 groups and 8 members for each group.
Quality of Service (QoS)
QoS classifies packets into different precedence classes. The packets are transmitted
and received according to their classified priorities. This mechanism helps
high-bandwidth demanding applications such as VoIP to get an unobstructed
connection.
SNMP
10
The Switch supports SNMP (Simple Network Management Protocol). It allows the
product to be monitored by an SNMP management station.
