The Logical Address switches are available with the Enhanced Monitor; these switches select the logical addresses for the Enhanced Monitor. The top switch sets the most-significant digit, and the bottom switch sets the least-significant digit.

The green READY indicator lights after the power-on diagnostics are complete and there are no failures. During normal operation, the light flashes if there is a pending error message. Once all error messages have been retrieved, the READY indicator stops flashing and remains on.

The amber ACCESSED indicator lights when the MODID line is accessed by the slot 0 device. Refer to Enhanced Monitor Board Jumpers on page B±4 for information on the jumper MODID jumper positions.

An auxiliary power connector (MONITOR BACKUP POWER SUPPLY) allows you to apply +5 volts to the Enhanced Monitor board to provide RS-232 communication with a host computer while the mainframe is not powered on. The jumper located just above the power connector determines whether you source the +5V standby voltage from the monitor backup power supply connector or from the 25-pin connector. (Refer to Enhanced Monitor Board Jumpers on page B±4 for information on the jumper positions.)
