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.
If the OS supports the power-saving mode, the green lamp flashes while the server is in the
power-saving mode. Pressing the POWER/SLEEP switch places the server back in the normal
mode.
The power-saving mode is available in Windows Server 2003. 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 disk drives in the hard disk drive bay.
This lamp lights in green every time any of such hard disk drives is accessed.
When the DISK ACCESS lamp is lit in amber, it indicates that a hard disk drive error occurred. To
identify a failed hard disk drive, see the lamps provided for each hard disk drive.
When the DISK ACCESS lamp flashes in green and amber alternately or in amber only, it indicates
that hard disk drives connected to the optional RAID Controller are in auto-rebuilding
(reconfiguration).
