Normal/Uplink Push Button
The Normal/Uplink push button on the rear panel of the Model DS309 hub allows you to select
uplink (MDI) or normal (MDI-X) wiring for port 9 on the hub. The port is configured for normal
wiring to connect to a PC when the push button is in the out position. When the push button is
pressed in, the port is configured for uplink wiring to connect to another hub or to a switch, using
a straight-through twisted pair cable.
The rear panel of the Model DS309 hub has nine automatic speed-sensing 10/100 Mbps network
ports and a power adapter receptacle for the supplied power cord.

Applications
Applications
The Model DS309 hub is designed to provide flexibility in configuring your network connections.
Each hub can be used as a standalone device or can be used with 10 Mbps or 100 Mbps hubs or
other interconnection devices in various configurations. The configuration examples in this section
illustrate the integration of the Model DS309 hub in various network environments using other
NETGEAR products.
10 Mbps or 100 Mbps Transmission with the Hub
Refer to the following illustration when connecting your Model DS309 hub. The illustration
shows a Model DS309 hub connecting users to a printer, servers, and a router.

Daisy Chaining Using Port 9
Port 9 is a switched half-duplex port that enables the Model DS309 hub to cascade to other 100
Mbps hubs, bypassing 100BASE-TX limitations. The following illustration shows how three
Model DS309 hubs can be cascaded to expand the network. Without the Switched port, a separate
switch unit, such as the Model FS308 switch, is needed to cascade the units together.

1. Prepare the Site
Prepare the Site
Before you begin installing your Model DS309 hub, prepare the installation site. Make sure your
operating environment meets the operating environment requirements of the equipment.
Characteristic
Requirement
Temperature
Ambient temperature between 0° and 40° C (32° and 104° F).
No nearby heat sources such as direct sunlight, warm air exhausts, or
heaters.
Operating humidity
Ventilation
Maximum relative humidity of 90%, noncondensing.
Minimum 2 inches (5.08 cm) on all sides for cooling.
Adequate airflow in room or wiring closet.
Operating conditions
At least 6 feet (1.83 m) to nearest source of electromagnetic noise (such
as photocopy machine or arc welder).
Power
Adequate power source within 6 feet (1.83 m).
2. Install the Hub
Install the Hub
To install your hub on a flat surface, you do not need any special tools. Be sure the hub is
positioned with at least 2 inches of space on all sides for ventilation.
To install the hub on a wall, measure the distance between the mounting holes on the back of the
hub and mark the wall to match the location of the mounting holes on the device. At the marked
location, screw into the wall the two screws that you received with the mounting kit included in
your package contents. Be sure to choose a location that is near the devices to be connected, is
close to an electrical outlet, and provides at least 2 inches of space all around the hub for
ventilation.
3. Connect Devices to the Hub
Connect Devices to the Hub
Before connecting the hub, be sure you review “Applications” for information about determining
the appropriate configuration for your networking needs.
To connect the hub:
1. Connect the devices to the 10/100 Mbps ports on the hub, using Category 5 UTP cable
with an RJ-45 plug.
Note: Ethernet specifications limit the cable length between your PC or server and
the hub to 328 feet (100 meters) in length.
2. Set the Normal/Uplink push button.
3. Connect one end of the DC power adapter cable to the power outlet on the rear panel of
the hub and the other end of the power adapter cable to the wall outlet.

Twisted Pair Cables
For two devices to communicate, the transmitter of each device must be connected to the receiver
of the other device. The crossover function is usually implemented internally as part of the
circuitry in the device. Most ports on hubs and repeaters have media-dependent interfaces with
crossover ports. These ports are referred to as MDI-X or normal ports. Computer and workstation
adapter cards are usually media-dependent interface ports referred to as MDI or uplink ports.
These two figures illustrate the use of straight-through and crossover twisted pair cables.

Verify Installation
When power has been applied to the hub:
•
•
The green Pwr (Power) LED on the front panel is on.
The green Link LED on each connected port is on.
When the hub is connected and operating, refer to the tables in “Front Panel LEDs” and “Vista RJ-
45 Network Ports with Built-in LEDs” for information about the LEDs and their activity.

Verify that the network adapter card is installed correctly

Make sure that the proper cable is installed, and check for
miswired cable pairs or loose connectors.
Make sure the port termination at both the hub and the
device end is correct. Check the crimp on the RJ-45
connectors. In a Fast Ethernet operation, the quality of the
crimp on the connector is important. It is also important that
only Category 5 cable is used and that it is certified for 100
Mbps operation.
Make sure the length of the UTP cable from the hub to the
device does not exceed 328 feet (100 meters).
Using cable test equipment, make sure that the cable meets
the crosstalk, attenuation, and impedance specifications as
required by the 100BASE-TX standard.

The port and hub might be functioning correctly. Data
collisions are normal on Ethernet networks and occur when
two or more computers transmit data on the network
simultaneously. Computers that caused the collision retry
transmission at different intervals until the transmission
succeeds. Excessive collisions can result when multiple
hubs are connected and when many computers are
connected on the network. Check and make sure that
cabling and duplex settings are correct.
