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.

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.)
