What is the RJ-45 to DB-9 pinout for the console and modem port on the Juniper Firewall device?

Problem or Goal:
Environment:
  • SSG devices
  • ISG devices
  • NetScreen devices -- NS25, NS50, NS204, NS208, NS5200, NS5400
Symptom:

  • make console cable

Solution:

The Console port of the SSG devices, ISG devices, and NetScreen devices (NS25, NS50, NS204, NS208, NS5200, NS5400) is a RJ-45 serial console port connector, for VT100 terminal emulator programs to perform local configuration and administration. 

The Modem port is also a RJ-45 serial console port connector, for establishing remote console sessions using dialup connections through a 9600 bps RS-232 cable. Dialing into the modem establishes the dialup console connection.

To create an RJ-45 to DB-9 adapter, use the following table for both the modem port and the console port:
