Serial management via console port
Solution
* RJ45 console port *
To construct a '
PC adapter' for serial management of most Cabletron/Enterasys devices having an RJ45 console port, the desired pinout is:
RJ45 DB9 Conductor
1 Tx 2 Rx Blue
4 Rx 3 Tx Red
5 GND 5 GND Green
2 DSR 7 RTS Orange
6 DTR 8 CTS YellowThe hookup between the PC's DB9 COM port and a device's RJ45 Console port would be:
COM port =>
PC adapter => RJ45 straight-through cable => Console port.
The adapter p/n 6380041, bundled into DB9 console kit 9372038 and RJ45 console kit 9372065, is gray and T-shaped, with a white sticker labeled "PC".
These parts are referenced in
3377.
If the sticker is missing, it probably has a different pinout, unless its a "home grown" adapter that was never labeled.
See
5130, for the procedure utilizing this part.
