ETHERNET PRINT SERVER
If a terminal is not attached to the serial port, you can still detect a boot error (typically network-related) via the LEDs. If the OK and network LEDs are blinking rapidly (2-3 times per second) in unison, a boot failure occurred. Once the EPS boots and is running normally, the OK LED will blink once every 2 seconds.
3.If all the tests pass successfully, but the code in the Flash-ROMs is corrupt, the EPS will attempt to download new code from a network host. Both the OK and Parallel LEDs will blink at the same time in this case. The screen shown in Fig. 3-3 will print to the serial port.
