Symptom Action
Try connecting a console terminal to the COM1 serial
communication port (Section 6.7). Check the baud rate
setting for the console terminal and the system. The
system baud rate setting is 9600. When using the
COM1 port, you must set the console environment
variable to serial.
If none of the above considerations solve the problem,
check that the J1 jumper on the CPU daughter board is
not missing. Refer to Appendix A for the standard boot
setting.
If the system has a customized NVRAM file, try
powering up or resetting the system with the Halt
button set to the “In” position. The NVRAM script will
not be executed when powering up or resetting the
system with the Halt button depressed.
For certain situations, power up using the fail-safe
loader (Section 2.8) to load new console firmware from
a diskette.
