Frequently Asked Questions - GCS1104 IOGEAR

How do I set up the IOGEAR GCS1104 network switch?

Connect the power adapter to the switch and plug it into an outlet. Use Ethernet cables to connect your devices (computers, printers, etc.) to any of the four ports. Connect one port to your router or modem to provide internet access. The switch will automatically negotiate speeds and duplex modes.

What is the maximum speed of the GCS1104?

Each port supports speeds up to 1000 Mbps (Gigabit Ethernet) with auto-negotiation for 10/100 Mbps devices.

Does the GCS1104 support PoE (Power over Ethernet)?

No, the GCS1104 does not support PoE. Each connected device requires its own power source.

Can I mount the GCS1104 on a wall?

Yes, the switch has mounting holes on the bottom for wall mounting. Use appropriate screws (not included) to secure it.

How do I know if the switch is working?

The Power LED should be solid green. For each connected port, the Link/Activity LED will be solid when linked and blink during data activity.

What should I do if a device does not get a network connection?

Check the Ethernet cable connection and ensure the cable is not damaged. Verify that the device's network adapter is enabled. Try a different port on the switch. If the issue persists, restart the switch by unplugging it and plugging it back in.

Is the GCS1104 managed or unmanaged?

The GCS1104 is an unmanaged switch, meaning it works out of the box with no configuration needed. It automatically learns and forwards traffic.

What is the power consumption of the GCS1104?

The switch consumes up to 2.5 watts, making it energy-efficient. It also supports IEEE 802.3az Energy Efficient Ethernet when connected to compatible devices.

Can I use the GCS1104 with a mix of Gigabit and Fast Ethernet devices?

Yes, each port auto-negotiates speed (10/100/1000 Mbps) and duplex, so you can connect devices of different speeds seamlessly.

How do I clean and maintain the switch?

Unplug the switch before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquids or sprays. Ensure ventilation holes are not blocked to prevent overheating.
