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

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

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.

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.
