Frequently Asked Questions - BS-GU2008 BUFFALO

What is loop detection and how does it work on the BS-GU2008?

Loop detection identifies network loops where data packets circle endlessly, causing network congestion. The BS-GU2008 sends detection packets every two seconds and blinks the Loop LED when a loop is found. To enable/disable, use the front switch and then reconnect power.

How do I mount the BS-GU2008 to a metal surface?

Use the included magnet kit. Attach the magnets to the bottom corners of the switch, then place it on a metal surface like a steel desk. Keep magnets away from media to avoid data corruption.

What do the LED indicators mean?

Power: solid green when on. Link/Act (per port): solid when link established, blinking during data transfer. 1000/100/10M: green for 1000M, orange for 100/10M. Loop: blinking red when loop detected.

Can I wall-mount the switch?

Yes. The BS-GU2008 has mounting holes on the base for wall screws. Use appropriate screws to secure it. Avoid mounting on unstable surfaces.

What should I do if the switch is not powering on?

Check the power cable connection to the switch and outlet. Ensure the outlet is working. If the Power LED remains off, try a different outlet or contact support.

Is the BS-GU2008 suitable for home use?

Yes, it's a compact 8-port Gigabit switch ideal for home or small office networks, providing fast wired connections for devices like PCs, printers, and game consoles.

How do I reset the loop detection setting?

Toggle the loop detection switch on the front panel, then disconnect and reconnect the power cable. The new setting takes effect after power cycling.

Can I use the switch without loop detection?

Yes. Keep the loop detection switch off to disable it. Note that without detection, loops may cause network issues. It's recommended to leave it on unless interference occurs.

What type of Ethernet cable should I use?

Use Cat5e or Cat6 cables for Gigabit speeds. For best performance, ensure cables are properly terminated and not damaged.

Does the switch support VLANs or managed features?

No, the BS-GU2008 is an unmanaged switch. It works plug-and-play without configuration. For VLANs, consider a managed switch.

Loop Detection

This unit can detect network loops that can cause interference in the network.

What Is a Loop?

multiple connections exist between two hubs, data may be sent in a loop around the network, wasting network capacity and never getting to its destination. This continuously circulating data may interfere with other network communication.

Loop Detection

Turning Loop Detection On and Off

Use the switch on the front of the BS-GU2008 to turn loop detection on and off.

1. Disconnect the power cable, then reconnect it.

Note: The setting isn't changed until power cable is disconnected and reconnected.

Caution :
