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.
