J_UID_OW (-Overwriting)
When the jumper J_UID_OW is set to Off
(default), the Red LED (Overheat/Fan Fail/
PWR Fail/UID LED) located on Pin 8 of the
Front Control Panel (JF1) will take precedence
over the Blue UID_LED located on Pin 7 of
JF1. When the Red LED is on, the Blue LED
will be turned off. When the RED LED is off,
the Blue UID_LED can be on or off. In other
words, the Red LED signal overwrites the Blue
UID_LED signal if J_UID-OW is set to off.
When the jumper J_UID_OW is On, the Red
LED (OH/Fan Fail/PWR Fail/UID LED) and the
Blue_UID_LED work independently. The Red
LED will have no effects on the Blue LED. See
the table on the right for jumper settings.
