Power/Sleep Lamp; Status Lamp - NEC N8100-1668F User Manual

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, pressing the POWER/SLEEP switch blinks the
POWER/SLEEP lamp in green and places the server in the power-saving mode. Press the
POWER/SLEEP 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.

Status Lamp

The STATUS lamp is on (green) while the server is operating normally. (The rear panel also has the
STATUS lamp on it.) If the STATUS lamp is off or turns amber and flashes, it indicates that the
server is in abnormal state.
The table below explains the STATUS lamp indication, the meanings, and the procedures.
