Introduction
Hamlet HN08GTX is a powerful, high-performance Gigabit
Ethernet switch with 8 ports capable of 10/100/1000 Mbps
auto-negotiation operation (NWay), which means the
switch could automatically negotiate with the connected
partners on the network speed and duplex mode.
It is ideal for micro-segmenting large networks into smaller,
connected subnets for improved performance, enabling the
bandwidth demanding multimedia and imaging
applications. Moreover, the 10/100/1000Mbps
auto-sensing ability provides an easy way to migrate
10/100Mbps to 1000Mbps network. Compared to the
shared 10Mbps or 100Mbps networks, the switch delivers
a dedicated 10/100/1000Mbps connection to every
attached client without bandwidth congestion issue.
This switch also supports auto MDI/ MDI-X function. Each
port could be used to connect to another switch or hub
without crossover RJ-45 cable.
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. Moreover, Green Ethernet and
IEEE 802.3az Energy Efficient Ethernet technologies are
supported to save power consumption.
The switch is plug and play without any software to
configure and also fully compliant with all kinds of network
protocols.

LEDs Definition
The Hamlet HN08GTX switch contains one power LED for
the device and 8 LED indicators (Link/Act) that show the
activity and connection status of each port.

Station Connection
Connect each station to the switch by twisted-pair cable.
Plug one RJ-45 connector into a RJ-45 port of the switch,
and plug the other RJ-45 connector into the station’s
network adapter. Power on the switch and then system is
ready.
Switches Connection
In making a switch interconnection, you could use any port
to connect another switch with straight or crossover cable.
As all the ports support auto MDI/MDI-X function, using a
straight cable to make a switch-to-switch connection is
allowed.
For cable selection, refer to the following table.
