Figure 132. Intel® Server Board D50TNP1SBCR Feature Identification
The D50TNP1SB and D50TNP1SBCR server boards include several jumper blocks to configure, protect, or
recover specific features of the server board. Refer to
A bank of eight POST code diagnostic LEDs are on the front edge of the server board (see following figure).
During the module boot process, the BIOS executes many module configuration steps, each of which is
assigned a specific hex POST code number. As each configuration step is started, the BIOS displays the given
POST code to the POST code diagnostic LEDs. The purpose of these LEDs is to assist in troubleshooting a
system hang condition during the POST process. The diagnostic LEDs can be used to identify the last POST
process to be executed. See
for a complete description of how these LEDs are read, and for a list
of all supported POST codes.
