Model GS504 4-Port Gigabit Switch Installation Guide
The NETGEAR
™
Model GS504 4-Port Gigabit Switch provides you with a low-
cost, high-performance network solution and is designed to anchor and
interconnect 10/100 megabits per second (Mbps) workgroups using gigabit fiber
links.
The Model GS504 switch has the following key features:
• Four full-duplex gigabit fiber ports with standard SC connectors
The ports support multimode optical fiber (SX) up to 525 meters (m) with
50 µ m. With 62.5 µ m fiber cable, the maximum distance is 260 m.
• Automatic address learning function to build the packet-
forwarding information table
The table contains up to 8,000 MAC addresses (that is, the switch can
support networks with as many as 8,000 devices).
• Full-duplex mode to double throughput of point-to-point connections by
letting individual ports transmit and receive concurrently when the other end
also supports full-duplex mode
The default is full-duplex mode if the connected device does not support N-
way negotiation. Most gigabit fiber links run in full-duplex mode.
• Wire-speed filtering and forwarding of the traffic with no delay
• Store-and-forward intelligent processing to minimize erroneous packets on
the network
• Easy plug-and-play installation with no software to configure, which saves
time and minimizes the potential for configuration errors

Front Panel
The front panel of the Model GS504 switch contains the following LEDs that
correspond to each network port: Activity (Rx/Tx) and FDX (full-duplex)/
Collision. Each fiber network port has its own Link LED (located to the right of
each 1000 Mbps port).

Rear Panel
The rear panel of the Model GS504 switch has fans for cooling and a standard
AC power receptacle for the supplied power cord.
Desktop Switching
The Model GS504 switch is used as a desktop switch to build a powerful
network that enables users to have 1000 Mbps access to a file server. If a full-
duplex adapter card is installed in the server or PC, a 2000 Mbps connection will
be provided to each server and PC.

Segment Switching and Bridging from 10/100 Mbps to
1000 Mbps
The Model GS504, as illustrated below, connects multiple power workgroups
and servers using high-speed gigabit fiber links. Each power workgroup is
anchored by a NETGEAR FS509 switch. Because each fiber link can be up to
525 m long, these workgroups can be located on separate floors or in different
buildings.
Before you begin installing your switch, 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 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 arc welder).
Power Adequate power source within 6 feet (1.83 m).

Installation on a Flat Surface
To install the switch on a flat surface, be sure to attach the rubber footpads to the
bottom of the switch.
Installation in a Rack
Refer to the following illustration when installing the switch in a rack.
To connect the switch:
1. Connect the devices to the network ports on the switch, using 50 µ m or
62.5 µ m multimode fiber cables with SC plugs.
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.
Refer to the following illustration when connecting the switch.
Note:
Ethernet specifications limit the cable length between your PC
or server and the switch to 525 m for 50 µ m and 260 m for 62.5 µ m
fiber.

Using the SC Connector
The duplex SC connector connects stations, hubs, and switches that support the
1000BASE-SX fiber interface. Each fiber link needs a clearly defined, external
crossover. In other words, the transmit port of one interface must be wired to the
receive port of the opposite interface and vice versa. Fiber cables must be
connected in this manner to transmit and receive data.
When power has been applied to the switch, verify that:
•The green Pwr 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.

Symptom Cause Solution
Power LED is off. No poweris received
at the hub. Check the power cord connections for the switch and the connected device.
Make sure all cables used are correct and
comply with Ethernet specifications.
Link LED is off or
intermittent. Port connection is not functioning. Check the crimp on the fiber connectors and make sure that the plug is properly inserted
and locked into the port at both the switch
and the connecting device.
Make sure all cables used are correct and
comply with Ethernet specifications.
Check for a defective adapter card, cable, or
port by testing them in an alternate
environment where all products are
functioning.
File transfer is
slow or
performance
degradation is a
problem.
Half- or full-duplex
setting on the
NETGEAR switch
and the connected
device are not the
same.
Make sure the remote link partner is set to
autonegotiate or forced to full-duplex
operation.
A segment or
device is not
recognized as
part of the
network.
One or more devices
are not properly
connected, or
cabling does not
meet Ethernet
guidelines.
Verify that the cabling is correct. Be sure all
cable connectors are securely positioned in
the required ports. Equipment may have
been accidentally disconnected.
FDX/Col LED is
blinking yellow
excessively.
Collisions are
occurring on the
connected segment.
Some collisions are normal when the
connection is operating in half-duplex mode.
Duplex modes are
mismatched. Recheck the link partner settings.
