2 5-/8-Port 10-/100-/Gigabit Switch with 1 PoE PD port Federal Communications Commission and Industry Canada Radio Frequency Interference Statements This equipment generates, uses, and can radiate radio-frequency energy, and if not installed and used properly, that is, in strict accordance with the manufacturer s instructions, may cause inter-ference to radio communication. It has been tested and found to comply with the limits for a Class A computing device in accordance with the specifications in Subpart B of Part 15 of FCC rules, which are designed to provide reasonable protection against such interference when the equipment is operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case the user at his own expense will be required to take whatever measures may be necessary to correct the interference. Changes or modifications not expressly approved by the party responsible for compliance could void the user s authority to operate the equipment. This digital apparatus does not exceed the Class A limits for radio noise emis-sion from digital apparatus set out in the Radio Interference Regulation of Industry Canada. Le présent appareil numérique n émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de la classe A prescrites dans le Règlement sur le brouillage radioélectrique publié par Industrie Canada. CE Warning This is a Class A product. In a domestic environment, this product may cause radio interference in which case the user may be required to take adequate measures to correct the interference.

El aparato eléctrico debe ser montado a la pared o al techo sólo como sea recomendado por el fabricante. 8. Servicio El usuario no debe intentar dar servicio al equipo eléctrico más allá a lo descrito en las instrucciones de operación. Todo otro servicio deberá ser referido a personal de servicio calificado. 9. El aparato eléctrico debe ser situado de tal manera que su posición no interfiera su uso. La colocación del aparato eléctrico sobre una cama, sofá, alfombra o superficie similar puede bloquea la ventilación, no se debe colocar en libreros o gabinetes que impidan el flujo de aire por los orificios de ventilación. 10. El equipo eléctrico deber ser situado fuera del alcance de fuentes de calor como radiadores, registros de calor, estufas u otros aparatos (incluyendo amplificadores) que producen calor. 11. El aparato eléctrico deberá ser connectado a una fuente de poder sólo del tipo descrito en el instructivo de operación, o como se indique en el aparato. 12. Precaución debe ser tomada de tal manera que la tierra fisica y la polarización del equipo no sea eliminada. 13. Los cables de la fuente de poder deben ser guiados de tal manera que no sean pisados ni pellizcados por objetos colocados sobre o contra ellos, poniendo particular atención a los contactos y receptáculos donde salen del aparato. 14. El equipo eléctrico debe ser limpiado únicamente de acuerdo a las recomendaciones del fabricante. 15. En caso de existir, una antena externa deberá ser localizada lejos de las lineas de energia. 16. El cable de corriente deberá ser desconectado del cuando el equipo no sea usado por un largo periodo de tiempo. 17. Cuidado debe ser tomado de tal manera que objectos liquidos no sean derramados sobre la cubierta u orificios de ventilación. 18. Servicio por personal calificado deberá ser provisto cuando: A: El cable de poder o el contacto ha sido dañado; u B: Objectos han caído o líquido ha sido derramado dentro del aparato; o C: El aparato ha sido expuesto a la lluvia; o D: El aparato parece no operar normalmente o muestra un cambio en su desempeño; o E: El aparato ha sido tirado o su cubierta ha sido dañada.

Any other trademarks mentioned in this manual are acknowledged to be the property of the trademark owners. 1. Introduction These switches provide (5) or (8) 10-/100-/1000-Mbps ports. They were designed for easy installation and high performance in environments where traffic on the network and the number of users increases continuously. Both switches have a built in Power Device (PD) feature on port 1. Using this port, you can power the switch from a PSE port over ordinary CAT5 cables. The small compact unit was specifically designed for small to medium workgroups. Install it where space is limited for smooth network migration and an easy upgrade to network capacity. 2. Key Features 5-/8-Port 10/100/1000 Mbps (Auto-negotiation) Switch Ports 5/8 have a built in IEEE 802.3af Power Device (PD) feature that allows the switch to get power from a PSE device over ordinary CAT5 cables. Unit is palm-sized with metal case Auto-detects full-/half-duplex modes for any port Offers dedicated full-duplex 2000-Mbps bandwidth Supports Store-and-Forward switching methods Includes IEEE 802.3x flow control for full-duplex and back-pressure flow control for half-duplex Provides non-blocking and non-head-of-line blocking full wire speed forwarding Supports Auto-MDI/MDI-X function for any port 3. Package Contents Your package should include the following items. If anything is missing or damaged, please contact Black Box Technical Support at or (1) Gigabit Ethernet Switch (1) Power Adapter: 120 VAC, 60 Hz U.S. plug for LPDG705A and LPDG708A; VAC, Hz, 0.4 A universal power supply with (2) power clips: (1) EU, (1) UK for LPDG705AE and LPDG708AE (1) User s Manual l Page 3

NOTE: The front panel of the LPDG705A is similar to the LPDG708A, except that is has six LEDs (1 power, 5 Link/Act) instead of eight LEDs. LED 5 on LPDG705A and LED 8 on the LPDG708A indicate the Link/Act status of the PoE port. LED Indicators on the switch LED Status Description Power LINK/ACT On Off On Off Flashing Power is on. Power is off. Port is for connection. No connection. Data is transmitting or receiving Rear Panel (Connections) Port 5 on the LPDG705A also functions as a PoE port. Port 8 on the LPDG708A also functions as a PoE port. Figure 4-2. Back panels of the LPDG705A and LPDG708A. Page l

5 Chapter 5: Connection 5. Connection TP Port and Cable Installation: 1. The switch s TP ports support MDI-/MDI-X auto-crossover, so you can use either straight through or cross over cables. 2. Use CAT5 or higher grade RJ-45 TP cable for 10/100 applications and CAT5e grade RJ-45 TP cable or above for gigabit Ethernet applications, to connect a TP port of the switch to an Ethernet device such as a workstation or a server. 3. Repeat the above steps, as needed, for each RJ-45 port to be connected to a 10-/100-/1000-Mbps TP device. For successful installation and good performance, follow the cabling requirements. Using cables with a lower specification than recommended will negatively impact network performance. For Fast Ethernet TP network connection, you must use CAT5 or higher cables that are up to 328 feet (100 meters) long. For Gigabit TP network connections, you must use CAT5e or higher cables that are up to 328 feet (100 meters) long. Power On: Power this switch from PoE PSE (Power Source Equipment) or from external DC power adapter. When connecting a PoE PSE, make sure that your PSE complies with 802.3af or 48 VDC 15.4 W. After the power is on, all LED indicators will light immediately. Then all LEDs will turn off, except for the power LED, which stays on l Page 5
