Table 3-6 describes the status LEDs on the system board. Open the top cover to view these LEDs. One LED
(DS1) is located under the processor extender board and cannot be observed during operation.

DS4
Lit (green) when BMC HEARTBEAT signal is present. If the heartbeat signal is
missing (or out of tolerance), it will be reported by firmware and an error message
will announce the problem.
Figure 3-6,
item 2
DS3
Lit (green) when the 3VP3 power rail in the system board is within specifications.
The 3V source is monitored by firmware. If a power problem exists, it will be
reported by firmware and server power will shut down. If this LED is out (while
others are lit), the most likely problems (in order of likelihood) are: malfunctioning
LED, malfunctioning LED circuit on system board, or malfunctioning CPU
module.

item 3
DS2
Lit (green) when the -12V power rail in the system board is within specifications.
The -12V source is monitored by firmware. If a power problem exists, it will be
reported by firmware and server power will shut down. If this LED is out (while
others are lit), the most likely problems (in order of likelihood) are: malfunctioning
LED, malfunctioning LED circuit on system board, or malfunctioning CPU
module.
