Troubleshooting
The Power light is not lit
The switch has no power.
• Make sure the power cord is properly connected to the switch.
• Make sure the power adapter is properly connected to a functioning power outlet. If it’s
in a power strip, make sure the power strip is turned on. If the socket is controlled by a
light switch, make sure the switch is in the on position.
• Make sure you are using the NETGEAR power adapter supplied with your switch.
The Port number light is not lit for a connected device or
stays on continuously
There’s a hardware connection problem.
• Make sure the cable connectors are securely plugged in at the switch and the device.
• Make sure the connected device is turned on.
• If the Ethernet cable is connected to a NIC or other Ethernet adapter, make sure the card
or adapter is installed correctly and is working.
• Make sure the cable is less than 328 feet (100 meters).

Introduction
The NETGEAR®ProSafe 5-Port Ggabit Ethernet Switch Model GS105A provides you with a
low-cost,reliable, high-performance switch to connect up to five different Ethernet-enabled
devices (such as computers, file servers and routers) at blazing Gigabit Ethenet speeds.
The GS105A Gigabit Ethernet Switch enables you to build a small network that gives you 10,
100, or 1000 Mbps access to other devices on the network. It provides a full, dedicated 1000
(or 100, or 10 Mbps) connection between two devices. If a device has full-duplex capability,
the GS105A switch provides a 2000 Mbps (or 200, or 20Mbps) connection. If your network is
configured to support Jumbo Frames, the GS105A will forward them, as well as honoring priority
tags at both the layer 2 and layer 3 level. This means the GS105A can instantly move even very
large files across your network. As an added benefit, this switch works with both Windows and
Macintosh computers.
Ethernet cables come as either straight-through or crossover cables—depending on whether
you’re connecting to a device (computer, server, or printer) or networking equipment (hub,
switch, or router). With the Auto Uplink™ feature, you don’t have to worry about which one
you use. Each port on the GS105A switch automatically configures itself correctly when you
plug in a device’s cable.
If you have a problem with your switch, NETGEAR offers support 24 hours a day and 7 days
phone (see the provided support information card for phone numbers).

1Prepare to Install the Switch
Decide where you want to place the switch. Find a flat horizontal surface — such as a table,
desk or shelf. The switch comes with wall-mounting screws. You’re welcome to use the screws if
you want to hang the switch in an open space on a wall.
Make sure the selected location is:
• Not in direct sunlight or near a heater or heating vent.
• Not cluttered or crowded.There should be at least 2 inches (5 cm) of clear space on all
sides of the switch.
• Well ventilated (especially if it is in a closet).
Also, you’ll need one Category 5 (Cat 5) Ethernet cable with RJ-45 connectors for each device
you want to connect to the switch. Each Ethernet cable must be less than 328 feet (100 meters).

2Install the Switch and Connect the
Other Devices
1. Place the switch on a flat surface or hook onto the screws.
2. For each device, insert one end of an Ethernet cable into the port in the device and insert
the other end into one of the Ethernet ports on the switch.
3. Connect the power adapter’s cord into the back of the switch and then plug the adapter
into a power source (such as a wall socket or power strip).
The Power light
should light up.
The corresponding Link LED for
each connected and powered device
should light when connected and flash
when activity occurs.If the connection is
10 Mbps or 100 Mbps, one of the LEDs
in the RJ-45 jack will light up. If the connection is 1000 Mbps, then both of the LED's
in the RJ-45 jack will light up.
Note: If any light doesn’t operate as indicated, go to the Troubleshooting section.
