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.
Checking 2 sections from flash: invalid checksum
found.
