Status
Power LED Off
When the unit is plugged into the wall socket and the Power LED is off, the unit is powered off. However,
the network can trigger a Wake On LAN event in order to perform management functions.
Power LED On
Displays during boot sequence and while the unit is on. During boot sequence, hardware initialization is
processed and startup tests are performed on the following:
●
Processor initialization
●
Memory detection and initialization
●
Video detection and initialization
NOTE:
If one of the tests fails, the unit will simply stop, but the LED will stay on. If the video test fails, the
unit beeps. There are no messages sent to video for any of these failed tests.
NOTE:
After the video subsystem is initialized, anything that fails will have an error message.
NOTE:
RJ-45 LEDs are located inside the RJ-45 connector on the top, rear panel of the thin client. The LEDs are visible when the
connector is installed. Blinking green indicates network activity, and amber indicates a 100MB speed connection.
IDE LED is Off
When the unit is powered on and the flash activity light is off, then there is no access to the system flash.
IDE LED blinks white
Indicates the system is accessing the internal IDE flash.
