Chapter 1
Introduction
The Switch provides 810/100/1000Mbps NWAY RJ-45 ports.
It was designed for easy installation and high performance
in an environment where traffic on the network and the
number of user increase continuously. With newest Gigabit
chip set, eTen 9” Gigabit Ethernet switch can fully support
highest speed without hanging on problem even when
Full-duplex full loaded.
The switch also provides automatic crossover detection
functionality on each port. It is simple and friendly to
up-link to another switch without crossover cable.
Comet Labs Quiet & Cool technology : No fan needed, no
noise. A specific design for better cooling flow.
The compact rigid desktop size was specifically designed
for ROBO (Remote Office & Branch Office) and medium to
large workgroups. The Switch can be installed where space
is limited; moreover it provides smooth network migration
and easy upgrade to network capacity. The 9” size can be
rack-mount on 10” or 19” cabinet.

Front Panel Layout
I. 8RJ-45 Gigabit Switch Ports
There are 8RJ-45 connectors on the front panel for
connecting to servers, workstation or other devices. The
Switch provides 810/100/1000Mbps switching ports that
could sense the 10/100/1000M speed and negotiate
Full/Half duplex mode automatically. These switching
ports allow users to connect the Switch to 10Base-T,
100Base-TX and 1000Base-Tdevices.

I. To connect the Switch to PCs, servers, and other
network devices
Use straight-through twisted-pair cable (Cat. 5) to connect the
Switch to PCs, servers and other network devices. Networks can
be built as figure shown.
II. To connect the Switch to a Switch or a Hub
Use straight-through twisted pair cable to connect the
Switch to another Switch or Hub on uplink port. If you
connect the Switches on port 1 to port 8, the cable should
be changed to crossover cable.
