Page 6: Overview
JetNet 3705 Industrial Power Over Ethernet (PoE) Switches have four ports 10/100 TX ports with PoE injector plus one 10/100TX up-link port( JetNet 3705 ) or four ports 10/100 TX ports with PoE injector plus one 100FX up-link port (multi-mode “-m” or single-mode “-s” models, JetNet 3705f ). - Page 7 The JetNet 3705 and JetNet 3705f Industrial Ethernet Switch can break a network into 5 distinct data links or segments (also called collision domains). Since all Ethernet nodes are able to recognize the occurrence of a collision, and since the detection of a collision is principal to the way Ethernet arbitrates media access, large domains containing many nodes can become quite cumbersome.

Hardware Installation 3. OPTIONAL – DC IN: JetNet 3705 and JetNet 3705f Series Industrial Ethernet Switch has an additional power jack for the connection of AC-DC power converters (wall-transformer type) designed for office use. Be sure that the output voltage is at 48V DC to power the unit. Refer to switch PWR LED to verify the power via the DC-IN jack. -
Page 16: Wiring The Ethernet Ports
Wiring the Ethernet Ports JetNet 3705 and JetNet3705f Series Industrial PoE Switch support 4 RJ-45 ports (JetNet 3705) with automatic MDI/MDI-X crossover, PoE Injector, and automatic 10/100Mbps data rate sensing for 10Base-T or 100Base-TX connections. Automatic MDI/MDI-X crossover allows you to connect to other switches, hubs, or workstations, without regard to using straight-through or crossover cabling. -
Page 17: Connecting To Pd
Be sure the twisted pair cable is bound with the standard RJ-45 pin, especially the pin 4, 5, 7 and If the RJ-45 is bound with the wrong pin number, Jetnet3705 will not recognize the PD and won’t forward DC 48V power to PD, since the JetNet 3705 series switch following the Alternative B mode. -

Page 20: Power Connections
Power Connections JetNet 3705 and JetNet 3605f is powered by 48V DC. You should verify that the output of your DC supply voltage, or AC-DC power adapter, is at 48V DC while under load. IMPORTANT: The power input range for the JetNet3705 series is from 44v to 57v, but to avoid damage and keep the switch with good performance, we strongly suggest you choice DC 48V as the power input. -
