16 Ports Nway Fast Ethernet Switch
Introduction
The Switch provides 16 10/100Mbps ports. It was designed for easy
installation and high performance in an environment where traffic on
the network and the number of user increasing continuously.
The 19-inch standard rack-mount 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.

Front Panel Layout
A. 16 RJ-45 10/100Mbps Switch Ports
There are 1~16 RJ-45 connectors on the front panel for connecting to
servers, workstation or other network devices. The Switch provides 16
10/100Mbps switching ports that could sense the 10/100M speed and
negotiate Full/Half-duplex mode automatically. These switching
ports allow users connect the Switch to 10Base-T and 100Base-TX
devices.

Rack Mounting
Optional Rack-mounting brackets are available to mount Switch in
standard EIA 19-inch rack. 16 port 10/100Mbps Switch is supplied
with two mounting brackets and eight screws. And please assemble
according to the following steps.
First, put the Switch on the flat surface. Locate the mounting brackets
on the sides of the Switch with the mounting holes on each.
Next, insert the screw through the bracket and into the bracket
mounting holes in the Switch. Then, place the Switch in to 19-inch
rack.

Installation
Note: The Switch supports the AUTO-MDIX function. Just make sure
the twisted-pair cables meet the ANSI/EIA/TIA
568A(straight-through) or 568B(crossover) specification.
A. How to connect the Switch to PCs, servers, and other network
devices
Connect straight-through twisted-pair cable (Cat. 5) to the Switch
and PCs, servers and other network devices. Then the network
environment can be built easily as the following figure showed.

B. How to UP-Link the Switch to a Switch or a Hub
Use CAT5 twisted pair cable to connect the Switch to another Switch
or Hub on any port. Don’t worry about to use straight-through cable or
crossover cable. The switch support AUTO-MDIX on all port.
