Electrical Maintenance - LED Indicator Checks
McIAS 1610 utilizes light emitting diode (LED) indicators on the SBC, telephony
interface and the Power Supply boards to signify specific system functions. If an LED
(other than Internal Signal Battery) on the Power Supply board is not lit, a voltage
problem exists. The board must be pulled and replaced.
