Overheat (OH)/Fan Fail/PWR Fail/UID LED
Connect an LED cable to pins 7 and 8 of JF1 to
use the Overheat/Fan Fail/Power Fail and UID

the UID LED indicator for the front panel UID

Jumper J_UID_OW is set to off (default), the
Red LED takes precedence over the Blue
LED. (See Page 2-31 for details.) Refer to the
table on the right for pin defi nitions.
