POWER/SLEEP Lamp
The green POWER/SLEEP lamp lights to indicate normal operation while the server is powered on. When the server is
powered off, the POWER/SLEEP lamp stays unlit.
If the OS supports a power-saving mode, the green lamp flashes while the server is in this power-saving mode. Pressing
the POWER switch places the server back in the normal mode.
A power-saving mode is available in Windows Server 2003. Some OS's allow you to set the server to automatically
switch to 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 the hard disk drives is being accessed.
When the DISK ACCESS lamp lights 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 green and amber alternately or amber only, it indicates that the hard disk drives
connected to the Internal RAID Controller are in auto-rebuilding mode (reconfiguration).
Access Lamps
The access lamps for the optical disk drive lights when the media in the drive is being accessed.
