FCC Compliance Statement
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there
is no guarantee that interference will not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception, which can be determined by
turning the equipment o and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit dierent from that to which the receiver
is connected.
• Consult the dealer or an experienced radio/TV technician for help.

Introduction
DS51072:
The DS51072 5-Port 10/100 Mbps Desktop Network Switch allows up to 5 computers
to communicate with each other over a Local Area Network (LAN). An Ethernet
switch can enable computers to share les, devices such as printers, and be used to
expand an existing network’s capacity with additional ports. Compatible with both
10Base-T (10 Mbps) and 100Base-TX (100Mbps) networks, this Fast Ethernet switch can
automatically detect the type of network (auto negotiation) and type of cable (auto
MDIX) and congure itself, making for a Plug-and-Play networking solution. Backed by
a StarTech.com 2-year warranty and free lifetime technical support.
DS81072:
The DS81072 8-Port 10/100 Mbps Desktop Network Switch allows up to 8 computers
to communicate with each other over a Local Area Network (LAN). An Ethernet
switch can enable computers to share les, devices such as printers, and be used to
expand an existing network’s capacity with additional ports. Compatible with both
10Base-T (10 Mbps) and 100Base-TX (100Mbps) networks, this Fast Ethernet switch can
automatically detect the type of network (auto negotiation) and type of cable (auto
MDIX) and congure itself, making for a Plug-and-Play networking solution. Backed by
a StarTech.com 2-year warranty and free lifetime technical support.

Installation
1. The Network Switch is designed to sit on a at surface (such as a desktop) or be
securely mounted to a wall or similar surface. If you wish to mount the Network
Switch, rst prepare the surface by installing mounting screws (not included)
otherwise skip to Step 5.
2. The distance between the centers of the two mounting sockets on the back of the
Network Switch are 8.75cm. Mark the distance on the wall, making sure your marks are
straight and level.
3. Depending on the mounting surface, use the appropriate tools and hardware to
install mounting screws into the surface. There should be a gap of approximately 2
mm between the head of the screw and the wall surface.
4. Place the Network Switch so that the wide openings of the mounting sockets are
over the screw heads. Slide the case downward so that the screw heads slide into the
narrow slots.
5. Connect one end of your network cable to an open port on the rear panel of the
Network Switch. Plug the other end of the cable into the RJ-45 port on your network
device (e.g. computer, router, another switch, etc.). Repeat for each additional network
devices you wish to connect to the Network Switch.
6. Plug one end of the power adapter into an open electrical outlet and plug the other
end into the DC connector on the side panel of the Network Switch. The Power LED on
the top of the Switch should now be lit.
7. Once the Switch is powered on, it will be automatically initialized, and all Link/Act
LEDs will ash momentarily, indicating that the system has been reset.

Troubleshooting
Power LED does not light up:
•
Check the connection of the power adapter into the Network Switch and electrical outlet.
• Plug the power adapter into a dierent electrical outlet.
Link/Act LED indicator does not light up when connected:
• Check the Ethernet cable connection at both ends, to make sure it is properly
plugged in.
• If running a patch cable from the Network Switch to the network device, try to
switch the ends of the cables.
• If using structured wiring which goes through a series of panels, try to connect a
device directly to the Network Switch with a single patch cable.
• Make sure the network device is powered on and the network interface is enabled
on it (check documentation for the network device).
• Connect the Ethernet cable to a dierent port on the Network Switch.
• If another port is available on the network device, try to move the cable to a
dierent port.
• Replace the Ethernet cable with a dierent cable.
Cannot share Internet connection on multiple computers after connecting
Network Switch to cable/DSL modem:
• Unlike a network/broadband router, a network switch is not designed to connect
two separate networks together (i.e. Internet (WAN) and home network (LAN)),
but rather to create/expand a network. Since many Internet Service Providers
(ISP) only provide a single connection (IP address), a network switch would allow
only one computer to access the Internet. A network router is rst required to be
able to share a single Internet connection with multiple computers on your local
home network. A network switch can then be used to expand the number of ports
available on your local network, if necessary.
