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.
