The front panel of the chassis houses five LEDs which you can view to display the
system’s operating state. The
DC750 Front Panel LEDs table describes the LEDs
on the front panel.
DC750 Front Panel LEDs
LED DESCRIPTION
System status Indicates system status:
• A green light indicates the system is operating normally.
• A blinking green light indicates the system is operating in a degraded
condition.
DC750 (Rev 1) only:
• An amber light indicates the system is in a critical or non-recoverable
condition.
• A blinking amber light indicates the system is in a non-critical condition.
IMPORTANT! The amber status light takes precedence over the green status
light. When the amber light is on or blinking, the green light is off.
For more information, see the DC750 System Status table on page 126.
Power Indicates whether the system has power or is sleeping:
• A green light indicates the system is operating normally.
• No light indicates the system is off.
• A blinking green light indicates the system is sleeping.
The sleep indication is maintained on standby by the chipset. If the system is
powered down without going through BIOS, the state in effect at the time of
power off will be restored when the system is powered on until the BIOS
clears it. If the system is not powered down normally, it is possible that the
power light will be blinking at the same time that the system status light is off
due to a failure or configuration change that prevents the BIOS from running.
Hard drive activity Indicates hard drive activity:
• A blinking green light indicates the fixed disk drive is active.
• No light indicates no drive activity, or the system is powered off or sleeping.
DC750 (Rev 1) only: An amber light indicates there is a fixed disk drive fault.
Drive activity is determined from the onboard hard disk controllers. The server
board also provides a header giving access to this light for add-in controllers.
NIC activity Indicates activity between the system and the network:
• A blinking green light indicates there is activity.
• No light indicates there is no activity.
