Question
What is the pinout for RJ45 to DB9 console adapter for the legacy Enterasys devices
Environment
  • 800-Series
  • N-Series
  • S-Series
  • K-Series
  • D-Series
  • G-Series
  • I-Series
  • All firmware versions
Answer
  • To construct a 'PC adapter' for serial management of most 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         Yellow
  • The hookup between the PCs DB9 COM port and a device's RJ45 Console port would be:
              COM port => PC adapter => RJ45 straight-through cable => Console port.
