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

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

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

m or

62.5

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

m and 260 m for 62.5

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.
