1.Indicators

Indicators are located on the front panel of the product. The functions of

each indicator are shown below.

Link/Act (Green)

On: Link established

Blinking: Data transfer

Blinking (1-second interval): Loop detected

Oﬀ: Link not established

1000/100/10M (Green or Orange)

On (Green): 1000 Mbps link

On (Orange): 100 Mbps link

Blinking (Green or Orange): Loop detected

Oﬀ: 10 Mbps link or no link

Loop (Red)

Blinking: Loop detected

Oﬀ: Normal

Power (Green)

On: Power on

Oﬀ: Power oﬀ

2. Loop detection switch

Switch loop detection on and oﬀ.

3. LAN ports

These are ports for connecting 1000BASET/100BASE-TX/10BASE-T devices.

4.Power connector

Connect the included power cable to this connector.

Loop Detection

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

network.

What Is a Loop?

If both ends of an Ethernet cable are connected to the same hub, or when

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

･Oﬀ: Loops are not detected.

･On: If a network loop is detected, the link/act, 1000/100/10M, and loop

LED on the front of this unit blink once per second.

Turning Loop Detection On and Off

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

oﬀ.

2. Disconnect the power cable, then reconnect it.

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

reconnected.

Caution :

・ While loop detection is enabled, the BS-GU2008 will send a loop

detection packet through the network every two seconds. If these

packets disrupt your network in any way, disable loop detection.

・ Loop detection cannot detect or block all types of loops.

When a Loop is Detected

Reconnect the wiring, making sure that no wires are connected in a

loop.

Precautions for Installation

• Do not install the device in an unstable location such as on an unsteady

table or an inclined surface.

• Do not place another hub or object that generates heat on top of this

unit.

• Please route all cables properly to prevent people from tripping over

them.

• Ensure the air vents on the product are not blocked by other equipment

or walls.

• Only use the power cable included with the product. Using other power

cables may result in damage or ﬁre.

Floor or Shelf Mounting

Attach the supplied rubber feet to the bottom corners of the unit before

use.

Mounting to a Metal Surface

To mount to a metal surface, such as the side of a steel desk, use the

"BS-MGK-A Magnet Kit" (sold separately). Attach the supplied rubber feet to

the bottom corners of the unit before using the magnet kit.

Caution:

・ Do not put ﬂoppy discs, magnetic cards, or other magnetic storage

media near magnets. Doing so may delete or corrupt data.

・ If the switch is secured by the magnet alone, it should be no more than

75 cm (29.5 in) from the oor.

Mounting to a Wall

To mount the unit to a wall, use 2 screws (not included) with the dimensions

shown below. Install the screws 78 mm (3.1 in) apart and slide the mounting

holes in the base of the BS-GU2008 over them.

Installation

Use screws where this section is

2 mm (0.08 in) or less.

φ6 mm (0.24 in)

2 mm (0.08 in)

3mm (0.12 in)

Federal Communication Commission Interference Statement

This equipment has been tested and found to comply with the limits for a

Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are

designed to provide reasonable protection against harmful interference

in a residential installation.

This equipment generates, uses and can radiate radio frequency energy

and, if not installed and used in accordance with the instructions, may

cause harmful interference to radio communications. However, there is no

guarantee that interference will not occur in a particular installation.

If this equipment does cause harmful interference to radio or television

reception, which can be determined by turning the equipment oﬀ and

on, the user is encouraged to try to correct the interference by one or

more of the following measures:

- Reorient or relocate the receiving antenna.

- Increase the separation between the equipment and receiver.

- Connect the equipment into an outlet on a circuit diﬀerent from that

to which the receiver is connected.

- Consult the dealer or an experienced radio/TV technician for help.

This device complies with Part 15 of the FCC Rules. Operation is subject to

the following two conditions: (1) This device may not cause harmful

interference, and (2) this device must accept any interference received,

including interference that may cause undesired operation.

Power saving (***)

* This unit automatically detects and adjust for straight or crossover

Ethernet cables, so either type of cable may be used.

** Site-terminated Ethernet cables are not recommended. Always use

preassembled cables.

*** This function automatically recognizes the port link status and the

length of Ethernet cables, then adjusts the operating power accordingly.

This also adjusts the power when the data is not transmitted (the device

connected to this switch should be compatible with IEEE802.3az EEE).
