Chassis Features and LEDs

Dell R720 Chassis Features and LEDs (Front)

Item Description
A Power button/Power LED:
  • Solid green = powered on
  • Off = powered 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.
B 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.

C 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.
D Video connector

Allows you to connect a VGA display to the chassis.

E LCD menu buttons

Allows you to navigate the control panel LCD menu.

F Information tag

A slide-out label panel that allows you to record system information such as Service Tag, NIC, MAC address and so on.

G LCD panel (also serves as the node locator LED)
Provides system ID, status information, and error messages. In addition to textual information, the panel displays the following colors:
  • Blue = chassis is operating normally
  • Amber = chassis needs attention; the LCD panel also displays an error code followed by descriptive text
  • Blinking blue = LED enabled to allow target chassis to be identified and located when working with multiple chassis in a cabinet

The node locator function on the LCD panel (front of chassis) and baseboard (rear of chassis) is enabled using the system identification (node locator) button or the Server Management Client Enable Locator LED command.

If the chassis is connected to AC power and an error has been detected, the LCD lights amber regardless of whether the chassis has been powered on.
H Hot-swappable hard drives
The LEDs at the top of 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 hard drives are initialized after system power is applied. Drives are not ready for insertion or removal during this time.
I SATA DVD-ROM drive or DVD+/-RW drive
DVD devices are data only.
J USB connectors

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

K vFlash media card slot
