Operating Modes
The PrintNet has a self test and internally controlled modes. These are:
Power-on Self Test
The power-on self test performs diagnostic tests on the PrintNet
processor, RAM, ROM, EEPROM, parallel ports, and network interface.
The STAT, ERR, and NET LEDs indicate which test is currently in
progress.
Run and Auto Reset Modes
Run Mode is the normal operating state of the PrintNet. Auto Reset mode
is entered when the watchdog timer is triggered and the Print Server
resets itself. In either mode, the STAT LED flashes at a varying rate,
depending on whether the unit IP address is configured. The Run Mode
and Auto Reset Mode indicator descriptions are given in Table 2.
