Tips on how to fix rj45 connector problem - 3Com NBX 3102 IP Phone

You could try two things, first update the driver to the network card. Try using slim driver from www.cnet.com located under download. If that doesn't work you can purchase a RJ45 card and just put it in from Microcenter.com

I just fixed the same 133 error, it's about the communication between motor module and upper panel. There is an 8 wires cable, uses standard RJ45 connectors. In my case, one of the RJ45 connector to motor module is poorly done by the manufacture, so the connection is not reliable, I re-do the connector, problem fixed.

You have to cut off the bad connector, strip the outer sheath about an inch down, untwist the wire pairs and put the wires in the correct slot on a new rj45 connector and use a crimping tool to crimp it. You could also buy a new cable for a couple dollars on monoprice.com.

I assume you are using this configuration to connect a phone and not data outlet.
The RJ11 connector is used for phones and the RJ45 is used for data.
The CAT6 cable has 8 wires and to wire this cable to a RJ45 connector 2 wires on the CAT6 cable are not connected.

Go to this site for a wiring diagram for RJ11 to RJ45.

you mean to say

rj45 connector slot

its on back panel of the fiery

like telephone connector (but its big RJ45 connector)

i have life 38, looking at rj45, copper facing you (flat side of Rj45),
read left to right
white, brown, space, space, brown, space, white, red.

it looks first white brown runs down one side of flat cable, and the other 3 core brown white red down the other side of flat cable.
Hope this helps you out.

If you are trying to use a USB plug as a NIC card, you need a converter, not an adapter.

per Wikipedia; "RJ45 is technically incorrect because the RJ45 standard specifies the mechanical interface but a different wiring scheme than T568A/B, which is often used for Ethernet and telephones." So it's a standard set by a wiring authority. Actually it should be called 8P8C.

If you have a BackUPS CS, you are probably either using it with the USB cable that is supplied or with the 940-0128A supplied by APC, which permits running the UPS in dumb mode. By building your own cable, you can now run the BackUPS CS models (and perhaps also the ES models) using smart signalling and have all the same information that is available as running it in USB mode.
The jack in the UPS may be easily use a 8 pin RJ45 connector. It is easy to construct the cable by cutting off one end of a standard RJ45-8 ethernet cable and wiring the other end (three wires) into a standard DB9F female serial port connector.

It will be cheaper to get a USB/PCMCIA network adapter.
