Description
Power-on
indicator, power
button
The power-on indicator lights when the system powered on. The power button
controls the power supply output to the system.
NOTE: On APCI-compliant operating system, turning off the system using
power button causes the system to perform a graceful shutdown before power
to the system is turned off.
Health indicator Indicates the health of the system.
● If the system is powered on and in good health, the indicator lights solid blue.
No corrective action is required.
● The indicator blinks amber if the system is on or in standby, and if any error
exists (For example, a failed fan). See the System Event Log or system
messages for the specific issue. For information about the event and error
messages generated by the system firmware and agents that monitor system
components, go to qrl.dell.com > Look Up > Error Code, type the error code,
and then click Look it up.Invalid memory configurations can cause a blank
screen or no video output. See the Getting help section.
System
identification
button
The identification button on the front and back panels can be used to locate
a particular system within a rack. When one of these buttons is pressed, the
corresponding system identification button on the back flashes until one of the
buttons is pressed again.
Press the system identification button to turn the system ID on or off.
If the system stops responding during POST, press and hold the system ID button
for more than five seconds to enter BIOS progress mode.
