2-2 Set up the Hardware
Install the Hardware Configure the I/O Chassis
Regardless of this switch setting, outputs are turned off when any of the following occurs:
- processor detects a runtime error
- an I/O chassis backplane fault occurs
- you select program or test mode
- you set a status file bit to reset a local rack
` If an EEPROM module is not installed and processor memory is valid, the processor's PROC LED indicator blinks,
and the processor sets S:11/9, bit 9 in the major fault status word. To clear this fault, change the processor from
program mode to run mode and back to program mode.
´ If the processor's keyswitch is set in REMote, the processor enters remote RUN after it powers up and has its
memory updated by the EEPROM module.
ˆ A processor fault (solid red PROC LED) occurs if processor memory is not valid.
˜ You cannot clear processor memory when this switch is on.
