Chassis Features and LEDs

Dell R720xd 24-Drive and 12-Drive Chassis Features and LEDs (Front)

Item Description
A Diagnostic indicators

Diagnostic indicators light up to display error status.

B Node locator (system identification) button

When the node locator (system identification) button on the front or rear panel is pushed, the LCD panel on the front and the node locator LED on the rear blink blue until one of the buttons is pushed again.

If the system stops responding during POST, press and hold the system ID button for more than five seconds to enter BIOS progress mode.

To reset iDRAC (if not disabled in F2 iDRAC setup) press and hold the button for more than 15 seconds.

The Server Management Client Enable Locator LED command also enables the LCD panel and baseboard node locator LEDs.
C Power button/Power LED:
  • Solid green = powered on
  • Off = powered off
On ACPI-compliant operating systems, turning off the system using the power button causes the system to perform a graceful shutdown before power to the system is turned off.
In standard operation, chassis power is controlled through Server Management Client functions. The power button does NOT completely remove AC power from the chassis; you also must disconnect the AC power cords from the chassis.
D NMI button

Used to troubleshoot software and device driver errors when using certain operating systems. This button can be pressed using the end of a paper clip.

Use this button only if directed to do so by qualified support personnel or by the operating system's documentation.

E Hot-swappable storage drives
The LEDs on each drive bay indicate drive status as follows:
  • Blinks green two times per second = identifying drive or preparing for removal
  • Blinks green, amber, and off = predicted drive failure
  • Blinks amber four times per second = drive failed
  • Blinks green slowly = drive rebuilding
  • Steady green = drive online
  • Blinks green three seconds, amber three seconds, and off six seconds = rebuild aborted
  • Off = drive ready for insertion or removal
    The drive status indicator remains off until all drives are initialized after system power is applied. Drives are not ready for insertion or removal during this time.
F Video connector

Allows you to connect a VGA display to the chassis.

G USB connector

Allows you to connect USB devices to the chassis. The ports are USB 2.0-compliant.
