The display board attaches to an interconnect board that functions as a link between the midplane
board and the display board.
The display board contains the power switch and the following status LEDs:
• Power LED
• System health LED

• External health LED
• Locator LED
For more detailed information about front panel LED behavior, see “Controls, Ports, and LEDs”
(page 28).
The display board includes a USB connector that supports USB 2.0 (480 Mbps).
The diagnostic panel provides failure identification for each component that has a detectable error
associated with it. For more information on the diagnostic panel LEDs, see “Controls, Ports, and
LEDs” (page 28).
WARNING! Ensure that the system is powered off and all power sources have been disconnected
from the server prior to performing this procedure.
Voltages are present at various locations within the server whenever an AC power source is
connected. This voltage is present even when the main power switch is in the off position.
Failure to observe this warning can result in personal injury or damage to equipment.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to follow
ESD safety precautions can result in damage to the server.
