RADIO FREQUENCY INTERFERENCE STATEMENT

Class B Digital Device. This equipment has been tested and found to comply

with the limits for a Class B computing device pursuant to Part 15 of the FCC

Rules. These limits are designed to provide reasonable protection against

harmful interference in a residential installation. However, there is no guarantee

that interference will not occur in a particular 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. If this equipment does cause harmful interference to

radio or telephone reception, which can be determined by turning the

equipment off and on, the user is encouraged to try to correct the interference

by one 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 an experienced radio/TV technician for help.

Caution:

Changes or modifications not expressly approved by the party

responsible for compliance could void the user’s authority to

operate the equipment.

To meet FCC requirements, shielded cables and power cords are required to

connect this device to a personal computer or other Class B certified device.

This digital apparatus does not exceed the Class B limits for radio noise

emission from digital apparatus set out in the Radio Interference Regulation of

the Canadian Department of Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant

les limites applicables aux appareils numériques de la classe B prescrites dans

le Règlement sur le brouillage radioélectrique publié par le ministère des

Communications du Canada.

Front & Back Panel

LB8415A-US is a space saving pocket size 8-port TX/FX Ethernet switch designed for wall-

mount or desktop. LED indicators and TX/FX ports are located on front and back panels

respectively. Back panel is equipped with seven TX ports, one FX port, and a DC receptacle.

The front panel displays arrays of LEDs indicating power & individual port activity.

Back Panel

Power Receptacle: Connect the supplied universal power adaptor to the receptacle on back

panel and then plug the cord into standard AC outlet with a voltage range

from 100 to 240

Fiber Port

Front Panel Power PortStatus

LEDs

LED indicators on the front panel convey status information to help you monitor and

troubleshoot the switch.

Power

This LED comes on when the switch is connected to the power adapter.

Port Status

Each port has a matching LED showing the port status. When port LED is on, it

indicates the corresponding port is connected with another switch/hub or

computer. When port LED blinks, it indicates exchanging data or packets

within the network is proceeding.

The table below provides detailed information on LEDs.

LED State Indication

Steady The port has established a valid network connection.

LNK stands for LINK.

LNK/ACT Flashing The port is transmitting or receiving data.

ACT stands for ACTIVITY.

Installation

Selecting a Site for the Switch

As with any electronic device, you should place the switch where it will not be subject

to extreme temperatures, humidity, or electromagnetic interference. Specifically, the

site you select should meet the following requirements:

•The ambient temperature should be between 32 and 104 degrees Fahrenheit (0 to

40 degrees Celsius).

•The relative humidity should be less than 90 percent, non-condensing.

•Surrounding electrical devices should not exceed the electromagnetic field (RFC)

standards for IEC 801-3, Level 2 (3V/M) field strength.

•Make sure that the switch receives adequate ventilation. Do not block the

ventilation holes on the side of the switch or the fan exhaust port on the rear of the

switch.

•The power outlet should be within 1.8meter (6 feet) of the switch.

Connecting to Your Network

Connect network cables from computers or network segments to the TX ports on the

back panel.
