Chapter 4: Troubleshooting
The RCS/3000 has several LED status indicators:
•
RCS/3000: There is a status LED, located on the lower right side of the back panel, next to
the power connector, that indicates the overall status of the unit.
•
Serial ports: There is an LED located above each of the four serial port connectors.
•
HUB and LAN: There is an LED located above each of the two ethernet ports.
The LEDs use red, yellow, and green lights and blinking combinations to indicate the status
of the components of the RCS/3000.
LED Displays
The LED display may differ depending on the state of the RCS/3000. When the RCS is
started, it runs a self-test. If no problems are encountered, it enters the operational state. The
LEDs may show different patterns in the self-test state than in the operational state. In
addition, the RCS/3000 can be in the firmware monitor. For instance, if the RCS/3000
encounters a fatal error during the self-test, it will enter the firmware monitor. Or you can
invoke the firmware monitor by pressing the reset button. The LED display may be different
in the firmware monitor.
Table 11-1 shows the normal and error LED colors and patterns displayed in the self-test,
operational state, and firmware monitor. Table 11-2 shows the meaning of the LED error
displays.
