USER MANUAL GS504 NETGEAR

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.

Features

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 m . With 62.5 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

Product Illustration

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).

The table below describes the activity of the LEDs.

Label	Color Activity Description
Power	Green	OnOff	Power is supplied to the switch.Power is disconnected.
FDX/Col Green	Yellow	OnOffBlinking	The port is operating in full-duplex mode.The port is operating in half-duplex mode.Data collisions are occurring on the port. In a full-duplex environment, there is no collision. In a half-duplex environment, some collisions are normal.
Activity Green	Blinking P	Packet trans	mission or reception is occurring on the port.
Link	Green	OnOff	A valid 1000 Mbps link is established on the port.A link is not established on the 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.

Applications

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.

Prepare the Site

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	nches (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

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.

Connecting Devices to the Switch

To connect the switch:

1. Connect the devices to the network ports on the switch, using 50 m or 62.5 m multimode fiber cables with SC plugs.

Note: Ethernet specifications limit the cable length between your PC or server and the switch to 525 m for 50 ∝m and 260 m for 62.5 ∝m fiber.

1. 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.

Model GS504 4-Port Gigabit Switch Installation Guide

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.

Tx Rx 8895FA

Verify Installation

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.

Troubleshooting Information

Symptom	Cause Solution
Power LED is off.	No power is 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.
