POWER/SLEEP Lamp ( )
The green POWER/SLEEP lamp lights to indicate normal operation while the server is powered.
When the server is off-powered, the POWER/SLEEP lamp stays unlit.
The POWER/SLEEP lamp indicates that the server is running in the power-saving mode (sleep
mode). If the OS supports the power-saving mode such as Windows 2000, pressing the SLEEP
switch blinks the POWER/SLEEP lamp in green and places the server in the power-saving mode.
Press the POWER switch to turn out the POWER/SLEEP lamp and place the server back in the
normal mode.
The power-saving mode is only available when the OS supports the power-saving feature. Some
OS's allow you to set the server to automatically turn in the power-saving mode when no access is
made to the server for a certain period of time or to select the power-saving mode with a command.
DISK ACCESS Lamp ( )
The DISK ACCESS lamp indicates the state of hard disks in the 3.5-inch hard disk drive bay.
This lamp lights in green every time any of such hard disks is accessed.
When the DISK ACCESS lamp is lit in amber, it indicates that a hard disk error occurred. To
identify a failed hard disk, see the lamps provided for each hard disk.
When the DISK ACCESS lamp lashes in green and amber by turns or in amber only, it indicates that
hard disks connected to the internal disk array controller are in auto-rebuilding (reconfiguration).
Access Lamps
The access lamps for the floppy disk drive and the CD-ROM drive light when access is made to a
media in the drive.
