Be sure the PmT1 and PmE1 circuit board is seated firmly in the baseboard and that the
baseboard is fully plugged in the chassis.
Be sure the system is not overheating.
Check the cables and connectors to be certain they are secure.
If you are using the PmT1 and PmE1 monitor, run the power-up diagnostics and check
the results. “Power-up Diagnostic/Test Commands”, Section describes the power-up
diagnostics.
Check your power supply for proper DC voltages. If possible, use an oscilloscope to look
for excessive power supply ripple or noise (over 50 mV
pp
below 10 MHz).
Check that your terminal is connected to serial port A (SMC1).
The PmT1 and PmE1 monitor uses values stored in on-card NVRAM (I
2
C EEPROM) to
configure and set the baud rates for its console port. The lack of a prompt might be
caused by incorrect terminal settings, and incorrect configuration of the NVRAM, or a
malfunctioning NVRAM. Try holding down the H character during a reset to abort
autoboot using NVRAM parameters. If the prompt comes up, the NVRAM console
parameters are probably configured incorrectly. Enter the command nvopen, then the
command nvdisplay, to check the console configuration. For more information about
the way NVRAM is used to configure the console port baud rates, refer to Chapter 8.
