When a Sun Ray Client boots, a spinning wheel icon is displayed by default. To show the details of the boot process and to help identify problems, you can use the Stop-O key sequence (or Ctrl-Pause-O on non-Sun keyboards) to display the On-Screen Display (OSD) icons. This condition persists across reboots. So, if you want to disable the OSD icons, you need to press Stop-O again.

The OSD icons are also displayed if you simultaneously press the three audio keys, if a warning or error occurs on the Sun Ray Client while it boots, or if a state change does not occur for more than ten seconds.

If you see the older version of the icons, the firmware has not been upgraded or is failing. To make sure that the Sun Ray Client is using the latest firmware, see Chapter 11, Sun Ray Client Firmware.
