JetNet 3705-24V 5-port Industrial Fast Ethernet Power over Ethernet Switch

Introduction

The JetNet 3705-24V Industrial Switch is 5-port Fast Ethernet switch with 4 IEEE-

802.3af PoE injectors with one DC booster for transportation PoE application. The

internal DC booster can boost Dc power from 24V to 48V to compliance with IEEE

802.3af Power over Ethernet standard. It offers 60 watts power budget to satisfy 4 ports

15.4w power consumption. With the rugged Aluminum alloy housing, the JetNet 3705-

24V survived under -25°C ~ 60°C environment temperature give your Power over

Ethernet application best reliability.

Ports

RJ-45 ports

The Fast Ethernet ports (RJ-45) will auto-sense for 10Base-T or 100Base-TX

connections. Auto MDI/MDI-X means that the switch can connect to another switch or

workstation without changing straight-through or crossover cabling. Please refer to

Table-2 for RJ-45 pin assignment.

2 Tx-

3 Rx+

6 Rx-

Table-2: RJ-45 Pin Assignment

Note “+” and “-” signs represent the polarity of the wires that make up each wire

pair.

All ports on this industrial switch supports automatic MDI/MDI-X operation, users can

use straight-through cables (See figures below) for all network connections to PCs or

Servers, or to other switches/hubs. In straight-through cable, pins 1, 2, 3, and 6, at one

end of the cable, are connected straight through to pins 1, 2, 3 and 6 at the other end of

the cable. Table-3 shows the 10BASE-T/100BASE-TX MDI and MDI-X port pin-outs.

Cabling

Twisted-pair segments can be connected with unshielded twisted pair (UTP) or

shielded twisted pair (STP) cable. The cable must comply with the IEEE 802.3u

100Base TX standard (e.g. CAT.5, CAT.5e, or CAT.6). The cable between the

equipment and the link partner (switch, hub, workstation, etc.) must be less than

100 meters (328 ft.) long.
