Applications
PC Workgr oup
The Model FS105 switch is used as a desktop switch to build a small
network that enables users to have 100 Mbps access to a file server.
Compared with a hub, where the network bandwidth is shared among
all users, the model FS105 switch provides dedicated 10 or 100 Mbps
(megabits per second) bandwidth to each PC.
If a full-duplex adapter card is installed in the server or PC, a 200
Mbps connection is possible on the port where the server or PC is
connected.

Auto Uplink™
The Auto Uplink technology that NETGEAR has included in this
product will automatically sense whether the straight-through cable
plugged into any port should have a ‘normal’ connection, e.g.
connecting to a PC; or an ‘uplink’ connection, e.g. connecting to a
router, switch, or hub. That port will then configure itself to the
correct configuration. This feature also eliminates the need to worry
about crossover cables, as Auto Uplink will accommodate either type
of cable to make the right connection.
Note:
Auto Uplink will compensate for setting uplink
connections, and crossover or straight-through cables.
Using Auto Uplink to create multiple paths between any
two network devices will disable your network.

Installing the Switch
Set the switch up on a flat surface; you do not need any special tools.
Be sure the switch is positioned with at least 2 inches of space on all
sides for ventilation.
Connecting Devices
To connect devices to the switch:
1. Connect the devices to the 10/100 Mbps ports on the switch,
using Category 5 UTP cable and an RJ-45 plug.
Note:
Ethernet specifications limit the cable length
between your PC or server and the switch to 328 feet
(100 meters).
2. Connect one end of the DC power adapter cable to the power
outlet on the rear panel of the switch and the other end of the
power adapter cable to the wall outlet.
Rear Panel
The rear panel of the Model FS105 switch has a power adapter
receptacle for the supplied power adapter.

Verifying Installation
When power has been applied to the switch:
• The green Pwr (power) LED on the front panel is on.
• The green Link LED on each connected port is on.
When the switch is connected and operating, refer to the table in
“LEDs” for information about the LEDs and their activity.

Make sure the attached device is
powered and there is a proper UTP

Make sure the network adapter card
installed in the PC is working. Verify that
the network adapter card is operating at
the proper speed (10 Mbps or
100 Mbps).
Make sure the proper cable is installed.
Check for miswired cable pairs or loose
connectors.
For 100 Mbps operation, only
Category 5 or better grade cable should
be used. For 10 Mbps operation,
Category 3 cable can be used.
Make sure the length of the UTP cable
from the switch to the device does not
exceed 328 feet (100 meters).
