DN-60021-1

Description
DN-60021-1 is 24-port 10/100Mbps unmanaged Ethernet Switch. Adopt professional
IP1725 switch chips, the switch provides 24 x 10/100Mbps Auto-Negotiation RJ45
ports. All RJ45 ports support the Auto-MDI/MDIX function. Every port can works as
uplink port or common port. The Switch delivers superior performance with improving
workgroup, network bandwidth, increasing network node, providing greater flexibility,
installation convenience. It is the best choice for increasing your speed.

Chapter 1 Introduction
Congratulations on your purchase of this 10/100Mbps switch. Instructions for
installing and configuring this product can be found in this manual. Before you install
and use this product, please read this manual carefully for full exploiting the functions
of this product.
The 10/100Mbps switch is the perfect way of integrating 10Mbps Ethernet and
100Mbps Fast Ethernet devices. All 24-ports are auto speed negotiating, and have
automatic MDI/MDI-X crossover detection, so you don't have to worry about the cable
type. Each port independently negotiates for best speed and half- or full-duplex mode,
for up to 200Mbps of bandwidth per port. Fast store-and-forward switching prevents
damaged packets from being passed on into the network.

Chapter 2 Installation
2.1 Front Panel LEDs
Power LED
This red indicator illuminates when the Switch is receiving power.
Link/Act
This green indicator illuminates steadily when a port is connected to a station
successfully, If this green indicator is blinking, it indicates that a port is transmitting or
receiving data on the network.
2.2 Back Panel Features
The power connector is located on the back panel of the switch.
AC Power Connector
This is the three pronged connector that support the power cord. Plug in the female
connector of the provided power cord into this connector, and the male into a power
outlet. Supported input voltages range from 100~240V AC at 50~60Hz.
2.3 Connecting Network Devices
To connect network devices to the Switch, follow these instructions.
1. Make sure all the devices you will connect to the Switch are powered off.
2. Connect a Category 5 Ethernet network cable to one of the numbered ports on
the Switch.
3. Connect the other end to a PC or other network devices.
4. Repeat steps 2 and 3 to connect additional devices.
5. Plug in the female connector of the provided power cord into the power connector
on the Switch’s back panel.
6. Plug in the male into a power outlet.
7. Power on the devices connected to the Switch. Each active port’s corresponding
LED will light up on the Switch.
