The recovery console (also referred to as Update and Recovery Firmware) can be accessed using an RS-232 serial interface terminal.

It can be used to flash (write to the Flash memory of) an appliance in order to replace the operating system, or reset/recover the configuration.

Booting into the recovery console

  1. Shut down the appliance
  2. Connect the appliance to a workstation using an RS-232 null-modem cable, usually included with the appliance. If no workstation with an RS-232 connector is available, USB-to-serial adapters can be purchased.
  3. Start a serial terminal emulator, for example PuTTY, HyperTerminal or minicom.
  4. Choose serial console, 9600 baud, 8 data bits, 1 stop bit, no parity.
  5. When using HyperTerminal, it is important to manually select VT100 as emulation.
  6. Start (connect the power to) the appliance

After a couple of silent hardware checks, the text below will be displayed. In the example, a key was pressed, and therefore the recovery console was chosen.
