Db9 rj45 pinout - 3Com Computers & Internet

Hi there,

You should have a DB9 to RJ45 converter in the box. This converter is used to change from DB9 serial to RJ45, which is the port on the DSR that is used to connect to the serial console.

Should you do not have such connector, call Avocent Tech Support, they will help you to get that converter.


The NullModem Cable might also be requiered

Google"RJ45 pinouts".There is some sight I found(free)that has connector pinouts for all kinds of stuff.There are several different ways to configure an RJ45(8 pin)jack,depending on the application.

Verify that the correct settings and cable/connectors (rollover cable, correct COM port specified) are being used when establishing the console connection.

From the manual-

3.9.2 Connecting to an IBM or Compatible Device

To connect an IBM PC or compatible device, running the VT terminal emulation, to an
Enterasys Networks module Console port (Figure 3-20), proceed as follows:
1. Connect the RJ45 connector at one end of the cable (not supplied) to the Console port on the
Enterasys Networks module.
Connecting to Console Port for Local Management
Hardware Installation 3-31
2. Plug the RJ45 connector at the other end of the cable into the RJ45-to-DB9 adapter (supplied
with the device).
3. Connect the RJ45-to-DB9 adapter to the communications port on the PC.
4. Turn on the PC and configure your VT emulation package with the following parameters:

Parameter Setting
Mode: 7 Bit Control
Transmit: Transmit=9600
Bits Parity: 8 Bits, No Parity
Stop Bit: 1 Stop Bit

If I am understanding correctly, you are using a serial to ethernet cable. The serial cable plugs into your laptop and the ethernet end plugs into the CONSOLE port on the Cisco.

From here you use a terminal emulation program like "Hyperterminal" to connect via the serial port. As long as your serial port is installed, no other drivers are necessary.

If not work, invert the RJ45 connector

This is for a newbridge or alcatel 3624 mainstreet channelbank - do not use the modem side, only use the terminal side - all is needed is Rx, Tx, and ground - if looking from the "window" side of rj45 connector, or pins-side up on rj45 socket.

this doesnt solve the guys problem. the cord he has is cat 5 cable with only four wires in it, the adaptor is made only by the company he got the msr206 from. best thing to do is to contact www.tyner.com and ask for a replacement adaptor.

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.

Hello

The pinout is determined by the serial port you are plugged into. Are you using serial port 1 or 2. This is pinout from a standard DB9 PC serial port should get you into SP1.
