not covered previously.
5. Slide the jumper fully onto these pins.

Level 2 diagnostic LED panel and system board LED locations
The following illustration shows the location of the LEDs on the level 2 diagnostic
panel, which is attached to the same metal frame as the hot-swap drive backplane.
You can view the diagnostic panel LEDs through a special cutout area on the top
cover, to the right of the cover-release latch. However, to determine the exact source
of the error condition in the server, you might need to remove the top cover to view the
location of a specific error LED on the system board.
The meanings of these LEDs are as follows:
EXP Attached expansion I/O failure
NMI Nonmaskable interrupt
Over Temp System over temperature condition
PCI PCI failure
VRM VRM failure
