Back-to-back
Two GC102 Gigabit Converters can be used to extend the reach of an all copper gigabit network, enabling
a work group or department to move to a different floor or nearby building. In this example, a network
based on two GS524T Gigabit Ethernet Switches remains connected via the long fiber run made possible
by the GC102.

PREPARE THE SITE
Before you begin installing your Converter, prepare the installaiton site. Make sure your operating
environment meets the operating environment requirements of the equipment.
Warning: Class 1 laser device.
Warning: Do not stare into the laser beam.
INSTALL THE CONVERTER
To install your converter on a flat surface, you do not need any special tools. Be sure the converter is positioned with
at least 2 inches of space on all sides for ventilation.
To install the converter on a wall, measure the distance between the mounting holes on the back of the converter and
mark the wall to match the location of the mounting holes on the converter. At the marks, screw into the wall the
two screws in the mounting kit included in your package contents. 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 converter for ventila-
tion.
CONNECT DEVICES TO THE CONVERTER
Before connecting the converter, be sure to review "Applications" on page 2 to determine the appropriate configura-
tion for your networking needs.
To connect the converter :
1.Connect the devices to the RJ-45 port on the converter, using Category 5 UTP cable and
an RJ-45 plug.
Note:Ethernet specifications limit the cable length between your converter and your switch, server or PC to
328 feet (100 meters).
2. Connect the device to the SC port on the converter, using mulitmode fiber cable and an SC connector.
Note:Ethernet specifications limit the cable length between your converter and your switch, server, or PC to
1,804 feet (550 meters).
3.Connect one end of the power adapter to the power outlet on the rear panel of the switch and the other end of
the power adapter cable to the wall outlet.
VERIFY INSTALLATION
When power has been applied to the Converter :
The green PWR (Power) LED on the front panel is on.
The green LNK LED on each connected port is on.
Refer to the table in the "LEDs" section for information about the LEDs and their activity.
Characteristic Requirement
Temperature Ambient temperature between 00and 400C (320and 1040F).
No nearby heat sources such as direct sunlight, warm air exhausts, or heaters.
Operating humidity Maximum relative humidity of 90%, noncondensing.
Ventilation 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 mace welder)
Power Adequate power source within 6 feet (1.83 m).
TROUBLESHOOTING INFORMATION
Symptom Cause Solution
Green Link LED is Port connection Make sure the attached device is powered and
off on an active port is not functioning there is a proper connection at that end.
Make sure the network adapter card installed in
the PC is working. Verify that the network adapter
card is 1000 Mbps capable and that the 1000 Mbps
LED and Link LEDs are on at the network adapter
card in the PC.
Make sure the proper cable is installed, and check
for miswired cable pairs or loose connectors.
Green Link LED Port connection Make sure the port termination at the Netgear GC102
intermittent is not functioning. Converter end and the device end are correct. Check
the an active port. crimp on the RJ-45 connectors.
It is also important that Category 5 cable or better is
used and that it is certified for 1000 Mbps operation.
Make sure the length of the UTP cable from the
converter to the device does not exceed 328 feet (100
meters) for copper connections or 1,804 feet (550
meters) for fiber connections.
REPLACEMENT POWER ADAPTER
If, for any reason, the power adapter for any of the hubs fails, please contact NETGEAR immediately to order a replace-
ment adapter. Use the following table when ordering a specific power adapter.
