24 Port Nway Fast Ethernet Switch
Introduction
The Switch provides 24 10/100Mbps ports. The Switch was
designed for easy installation and high performance in an
environment where traffic on the network and the number of user
increase 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.

I. 24 RJ-45 10/100Mbps Switch Ports
There are 1~24 RJ-45 connectors on the front panel for connecting
to servers, workstation or other devices. The Switch provides 24
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.All ports support Auto MDIX crossover capability.

Rack Mounting
Optional Rack-mounting brackets are available to mount Switch in
standard EIA 19-inch rack. 24 port 10/100Mbps Switch is supplied
with two mounting brackets, eight screws.
First, put the Switch on the flat surface. Locate the mounting bracket
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
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 build
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 24, the cable should be changed to crossover cable.
