Missing Rear Display Module failure

Description

The rear display module stores the chassis identity and is required to boot a product image. If Service OS detects that the rear display module is not inserted at boot time, a message will be printed and Service OS will force boot to the Service OS console.

Example

ServiceOS GT.01.01.0001 switch ttyS0

To reboot without logging in, enter 'reboot' as the login user name.

  Warning: no rear display module detected. A rear display module must be
  inserted to boot a product image. Check that a module is inserted and
  fully seated, then reboot the management module.
