failure or power failure. The Blue LED on pin
7 works as the UID LED indicator for the front
panel UID switch located on pins 13~14 of
JF1. When Jumper J_UID_OW is set to off
(default), the Red LED takes precedence
over the Blue LED. (See Page 2-19 for

4 of JF1 and attaches to the reset switch on
the computer chassis. See the table on the
