雪平问:我的NT网,网卡和HUB都是10/100M自适应的,近距离能通,距离远了就不通了(没超过100米),但是换成10M的HUB就能通,经销商说,用100M的HUB和用10M的HUM连线是不同的,请问该怎么连线才能通? 老二哥答:这个问题可能是由于RJ45头接线错误,必须是1、2,3、6成对,其余不影响 jingyu答:应该不是连线的问题,100M和10M的连线均使用1236。我认为更有可能是兼容性或线缆质量的问题 alsun答:我也遇到过这个问题,原因有2点:(1)必须使用100兆的网线,即五类或超五类线,因为五类线是由两根绞在一起的一对线,共四对组成。(2)按标准接线,必须保证(1,2)使用的是绞在一起的一对线。同理(3,6)即1为橙白,2必须为橙。 原理:100兆是对网线的要求比10兆苛刻,不用一对线就达不到100米的距离,10兆时则无此要求。实际上如果按照EIA的标准10兆和100兆网线的接法是一样的,只是线缆不一样。
Snow Ping Q: My NT network, network adapters and HUB are 10 / 100M adaptive, close to pass, the distance is no longer pass (no more than 100 meters), but replaced by 10M HUB can pass, distribution Business, said with 100M HUB and 10M HUM connection is different, how can I connect to the second brother A: This problem may be due to RJ45 head wiring error, it must be 1,2,3,6 Pairs, the rest does not affect jingyu A: It should not be a connection problem, 100M and 10M are connected using 1236. I think it is more likely to be a problem of compatibility or cable quality alsun A: I have also encountered this problem for two reasons: (1) 100 megabytes of network cable must be used, that is, Category 5 or Category 5 cable because Category 5 line is composed of two twisted together a pair of lines, a total of four pairs. (2) By standard wiring, it must be guaranteed (1, 2) to use a pair of twisted wires. Similarly (3,6) that is 1 is orange and white, 2 must be orange. Principle: 100 trillion is the requirements of the network cable than 10 trillion harsh, without a pair of lines up to less than 100 meters away from the 10 trillion is no such requirement. In fact, according to the standard EIA 10 trillion and 100 trillion network cable connection is the same, but the cable is not the same.
