Serial Console Connection

About establishing a serial console connection to a BIG-IP system

In the event that network access is impaired or not yet configured, the serial console might be the only way to access your BIG-IP® system.

Important: You should perform all BIG-IP software installations and upgrades using the serial console, as these procedures require reboots, in which network connectivity is lost temporarily.

Additionally, you should connect to the console to run End-User Diagnostics (EUD) tests.

Configuring a serial connection between a BIG-IP system and a serial console server

Depending on which BIG-IP® system you have, you can use either the supplied RJ45 to DB9 console port cable, serial console cable, or the RJ45F to RJ45M rolled serial adapter to connect the system to a serial console server.
  1. Connect the system to a serial console server using one of these options:
    • Connect the RJ45 to DB9 console port or serial console cable supplied by F5® to the CONSOLE port on the system.
      Note: The default serial port settings are 19200, n, 8, 1.
    • Connect the RJ45F to RJ45M rolled serial adapter to the CONSOLE port if you are connecting the system to a serial console server with a standard CAT5 cable, and then connect the CAT5 cable to the adapter. The adapter provides the appropriate pinout connection to your equipment.
  2. Connect the console port cable from the system to a management workstation or console server.
  3. Power on the system.
  4. Log in using the default user name root and the default password default.
    Note: If you cannot see or read output on the serial console, make sure that the baud rate is set to 19200.
