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 is initialized, anything that fails will have an error message. NOTE: RJ-45 LEDs - 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.
