【Dimension】

The series of products are the same size, and the number of the

Ethernet interface is different. Unit (mm)

【Power supply input】

The switch have redundant power input, provides one terminal

block (4 bits) for PWR1 and PWR2 input. The redundant power

can be used single and used two self-governed power to supply to

the system, PWR1 and PWR2 input at the same time, when

neither of

these two power fails, the other power acts as a

backup, and automatically supplies power needs, ensure running

Ethernet reassuring. Voltage input range is 12～48VDC (terminal

block defined as: V1-、V1+、V2-、V2+).

【DIP Switch】

Provide 10 bits switch for function setting. 1～8 alarm enable

switch setting, ON show enable. 9 show PWR2 alarm setting, 10

show PWR 1 alarm setting, ON show alarm state.

【Relay connection】

The relay consists of the two middle contacts of the terminal

block on the switch's top panel. The two terminal block connector

are used to detect both power faults and port faults. The two wires

attached to the Fault contacts form an open circuit when:

(1) The switch have lost power from one of the DC power inputs.

(2) One of the ports for which the corresponding Port alarm DIP

Switch is set to ON is not properly connected.

If neither of these two conditions occurs, the alarm circuit will be

closed.

【Communication connector】

10/100BaseT(X) Ethernet port

The pinout define of RJ45 port display as below, connect by UTP

or STP. The connect distance is no more than 100m. 100Mbps is

used 120Ωof UTP 5, 10Mbps is used 120Ωof UTP 3 ,4, 5.

RJ 45 port support automatic MDI/MDI-X operation. can

connect the PC, Server, Converter and HUB .Pin 1,2,3,6

Corresponding connection in MDI. 1→3, 2→6, 3→1, 6→2 are

used as cross wiring in the MDI-X port of Converter and HUB.

10Base-T/100Base-TX are used in MDI/MDI-X, the define of Pin

in the table as below.

10/100Base-T(X) MDI (straight-through cable)

10/100Base-T(X) MDI-X (Cross over cable)

MDI/MDI-X auto connection makes switch easy to use for

customers without considering the type of network cable.

100Base-FX Fiber port

100Base-FX full-duplex SM or MM port, SC/ST/FC type .The

fiber port must be used in pair, TX (transmit) port connect remote

switch's RX(receive) port; RX(receive) port connect remote

switch's TX(transmit) port.

The optical fiber connection supports the line to instruct

enhance the reliability of network effectively.

Suppose: If you make your own cable, we suggest labeling

the two sides of the same line with the same letter (A-to-A and

B-to-B, shown as below, or A1-to-A2 and B1-to-B2).
