## Introduction

|
The Cute-WR-DP is the enhanced version of

The CUTE-WR-DP is the enhanced version of
|
|
|
|
[CUTE-WR](https://www.ohwr.org/project/cute-wr/wiki) with dual WR ports.
|
|
|
|
|
|
|
|
|
|
|
|
There are three function mode for CUTE-WR-DP.
|
|
|
|
*Normal WR node**
|
|
|
|
|
|
|
|
The two ports can act in different modes:
|
|
|
|
In this mode, CUTE-WR-DP acts as a normal WR node with one SFP
|
|
|
|
port(SFP0).
|
|
|
|
|
|
|
|
*Parallel mode (Cute-WR-DP-PM)**
|
|
|
|
*Chain mode(CUTE-WR-DP-CM)**
|
|
|
|
|
|
|
|
In PM mode both port acts as down-link port connect to different WRS,
|
|
|
|
provide redundancy to improve the relibility for safety related
|
|
|
|
applications. Two WRPC work simultaneously on each port, the switch over
|
|
|
|
efforts developed on WRS can be adapted.
|
|
|
|
|
|
|
|
*Chain mode(Cute-WR-DP-CM)**
|
|
|
|
In CM mode, two ports act as one down-link(SFP1) and one up-link(SFP0)
|
|
|
|
to support cascade topology. Two ports also support simple switch
|
|
|
|
function for normal Ethernet packets.
|
|
|
|
|
|
|
|
In CM mode, two ports act as one down-link and one up-link to support
|
|
|
|
cascade topology.
|
|
|
|
*Parallel mode (CUTE-WR-DP-PM)**
|
|
|
|
|
|
|
|
The CUTEWR-DP board can also be used as normal WR node when only one
|
|
|
|
port is used.
|
|
|
|
In PM mode both port act as down-link port connect to different WRS,
|
|
|
|
provide redundancy to improve the relibility for safety related
|
|
|
|
applications. Current firmware doesn't support this
|
|
|
|
function.
