【Power supply input】

The switch support dual redundant power supplies: Power Supply

1 (P1) and Power Supply 2 (P2). The switch rear panel provides

power sockets for AC100~240V power entered. Socket diagram is

as follows:

The redundant power can be used independently. P1 and P2 can

supply power at the same time, once either of these two powers

fails, another power can acts as backup automatically to ensure

reliability of the network.

Important notice:

1. Power ON operation: Please connect to the device at first and

then connect to the power supply with power cable.

2. Power switch "—" means power ON, "O" means power OFF.

3. Power OFF operation: First, the powers switch to the "O" side

and then disconnect the power supply. Finally disconnect the

connection between the device and the power cord.

【Relay connection】

Relay access terminals in the rear panel of the device, next to the

power input parts, R+ and R- are in the middle of the relay alarm

output section. It is used to detect both power failure and port

failure. The open circuit state in normal non alarm state, when

there is any alarm information to the closed state. This series of

switch device have 2 relay alarm output, external alarm lights or

alarm buzzer or external switch signal acquisition device in order

to timely notify operators when an alarm occurs.

【Console port】

This switch provided 1pcs procedure test port based in serial port.

It adopts RJ45 interface, located in top panel, can configure the

CLI command through RJ45 to DB9 female cable.

【Communication connector】

10/100/1000BaseT(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. That can

connect the PC, Server, Converter and HUB. Pin 1, 2, 3, 4, 5, 6, 7,

8 Corresponding connections in MDI. 1→3, 2→6, 3→1, 4→7,

5→8, 6→2, 7→4, 8→5, are used as cross wiring in the MDI-X

port of Converter and HUB. In MDI/MDI-X, 100/1000Base-TX

PIN defines is as follows:
