System board illustration
The following illustration shows the system-board components, including connectors for user-
installable options, for the blade server.

Using system board switches
This section describes the system board switches on your Intel® Server Compute Blade SBX82.

NOTE
The illustrations in this document might differ slightly from your hardware.
Figure 4 on page 14 and Figure 5 on page 15 show the LEDs on the system board for the Intel®
Server Compute Blade SBX82. Refer to Table 1 and Table 2 on page 15 for more information about
the Light Path Diagnostics LED locations and settings. Refer to these illustrations and tables when
solving problems with the blade server.
✏
NOTE
Power is available to relight the Light Path Diagnostics LEDs for a small period of time after
the blade server is removed from the SBCE unit. During that period of time, you can relight
the Light Path Diagnostics LEDs for a maximum of 25 seconds (or less, depending on the
number of LEDs that are lit and the length of time the blade server is removed from the
SBCE unit) by pressing the Light Path Diagnostics button. The Light Path Diagnostics
power present LED (CR111) lights when the Light Path Diagnostics button is pressed if
power is available to relight the blade-error LEDs. If the Light Path Diagnostics power
present LED does not light when the Light Path Diagnostics button is pressed, no power is
available to light the blade-error LEDs, and they will be unable to provide any diagnostic
information.
