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.
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,or 5 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

Functional Description
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 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 port-based
VLAN.Port-based VLAN classifies incoming packets to VLANs according to
their ingress port.
Trunk (Aggregation)
The Trunk functionality integrates several ports to enlarge the bandwidth
that helps to boost the backbone connectivity. The switch allows the
Maximum 2 group and 4 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.
