2. Introduction To 8+2 Gigabit NWay Switch
2.1 General Description
The device is a powerful, high-performance 8+2 10/100/1000Mbps Fast Ethernet and
Gigabit switch, with eight 10/100Mbps ports and two 1000Mbps ports. All ports support auto
MDI-X function and auto-negotiation operation (NWay), which means the switch could
automatically negotiate with the connected partners on the network speed and duplex mode.
The Gigabit copper switching ports are ideal for micro-segmenting large networks into
smaller, connected subnets for improved performance, enabling the bandwidth demanding
multimedia and imaging applications. The Gigabit ports also provide the fat pipe to the
server or backbone connection for boosting the total system performance.
Moreover, the 10/100/1000Mbps auto-sensing ability provides an easy way to migrate
between 10Mbps, 100Mbps or 1000Mbps on networks with no pain. Compared to the
shared 10/100/1000Mbps networks, the switch delivers a dedicated 10/100/1000Mbps
connection to every attached client with no bandwidth congestion issue.
Store-and-forward switching mode promises the low latency plus eliminates all the network
errors, including runt and CRC error packets. To work under full-duplex mode, transmission
and reception of the frames can occur simultaneously without causing collisions as well as
double the network bandwidth.
The switch is plug-n-play without any software to configure and also fully compliant with all
kinds of network protocols. Moreover, the rich diagnostic LEDs on the front-panel can
provide the operating status of individual port and whole system.
For network connection:
The switch can use the following types of cabling:
10BASE-T: Category 3, 4 or 5 UTP/STP
100BASE-TX: Category 5 UTP/STP
1000BASE-T: Category 5 UTP/STP
Category 5 cable is preferred to use with this product in structured wiring
environments. This will ensure correct operation of all ports at 10Mbps, 100Mbps or
1000Mbps.

2.3 The Front Panel
The front panel of the switch is shown as below.
The auto-negotiation feature of the switch allows each port of the device running at one of
the following operation modes:
Port Speed Duplex Mode
Half-duplex 100 Mbps
Full-duplex
Half-duplex
10/100 Mbps
10 Mbps
Full-duplex
1000 Mbps Full-duplex
100 Mbps Full-duplex
1000 Mbps
10 Mbps Full-duplex
Each port supports auto MDI-X capability, that is the port could connect either the PC or hub
without any cable adjustment.
Warning: The RJ-45 ports are shielded data sockets. They cannot be used as telephone
sockets. Only RJ-45 plugs are allowed to connect these sockets

2.3.2 Port LEDs
Port LED indicators are located on the front panel for showing the operating status of
each port.
2.3.2.1 10/100Mbps port LED
Every port has a 100M LED. Steady green indicates that the port is operating
at 100Mbps. If the LED is off, the link speed is 10Mbps.
2.3.2.2 Link/Act LED
Every port has a Link/Activity LED. Steady green indicates that the port has
good linkage to its associated devices. Flashing green indicates there is
traffic transverses the port.
If the port is connected but the Link/Activity LED is dark, check the following
items:
1. The switch and the connected device’s power are on or not
2. The port’s cable is firmly seated in its connectors in the switch and in the
associated devices.
3. The connected cable is good and with correct type
4. The connecting device, including any network adapter is functioning.
2.3.2.3 Gigabit LEDs
There are four LEDs for Gigabit switching port.
2.3.3 Console Port
Through the console port, it provides rich diagnostic information includes network
statistics, link status and system setting. The operating mode of the console port is:
DCE
19200 ( Fix baud rate )
n ( No parity checking )
8 ( 8 Data bits )
1 (1 stop bit )
None ( None flow control )
You could use a normal RS-232 cable and connect to the console port on the device.
After the connection, you could run any terminal emulation program (Winterm,
Telix, … and so on) to enter the startup screen of the device. All the detail software
operation, please refer to “Console Program” session.
