Either one of the external power sources or one of the 2064’s power sup-
plies has malfunctioned. The DACS will function normally indefinitely
with one power supply. To verify the suspected problem, contact Patton
Technical Support to determine whether the DACS needs to be replaced
or not.
CPU FAIL LED is lit

soon as possible, unplug both power cables from the DACS, wait 30 sec-
onds, then plug the cables back into the DACS to see if the problem dis-
appears. If the
CPU FAIL LED remains lit after the DACS completes the
power-up cycle, contact Patton Technical Support to determine whether
the DACS needs to be replaced or not.

or not.
