Configuring and using the COM ports

After running the First Boot Wizard, it's possible to use the supplied serial cable to configure the hosting appliance using the front or back COM port in conjunction with a terminal emulator. Refer to the table below for pin-outs.

COM port 1 provides login access and can be used to view the hosting appliance boot process. COM port 2 access is enabled after the hosting appliance has been configured and only provides login access. It is recommended that you connect to COM port 1 and wait for the Login prompt before entering any data. The settings for both COM ports are as follows:
