Status LEDs<br />
The diagnostic LEDs listed in Table 1-7 show the status of applied<br />
voltages to the board. The position of the diagnostic LEDs on the board<br />
is indicated by a white rectangle in Figure 1-29.<br />

No. Name Color Description Normal<br />
Operating Condition<br />
LD1 2.5 V Green 2.55 V Input voltage present On<br />
LD2 3.3 V Green 3.3 V Input voltage present On<br />
LD3 5 V Green 5 V Input voltage present On<br />
LD4 -15 V Green -15 V Input voltage present On<br />

Additionally, the board has four green LEDs that are directly connected<br />
to the micro controller. They indicate the state of the micro controller<br />
and possible error bits and can be used for software debugging. See<br />
Table 1-8 on page 1-39. The position of the status LEDs on the board is<br />
indicated by a white oval in Figure 1-29 on page 1-38.<br />
