M204 LED’s

PWR Power supply.

STAT System status.

ERR System error.

NET Data to network.

The seven-stage power-on self test performs diagnostics on the

processor, RAM, ROM, EEPROM, serial ports, parallel ports,

and network interface. The STAT, ERR, and NET LEDs indicate

which test is currently in progress.

Run Mode is the normal operating state of the M204. Auto-Reset

mode is entered when the watchdog timer is triggered and the

Print Server has reset itself. In either mode, the STAT LED

ﬂashes differently depending on whether the unit’s IP address is

conﬁgured and COM1 monitor is active.
