J_UID_OW (-Overwriting)
When the jumper J_UID_OW is set to Off (de-
fault), 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. In
this case, 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.
