Table 11-2: LED Indicators for Error Conditions
LED Color/pattern During Error
Status red, blinking self-test Fatal error detected. LED blinks a HEX
code that designates the error category.
See Table 11-3 below.
green/yellow,
blinking operation An error was detected when reading the
current configuration database; the
default configuration database was
loaded instead.
red, blinking operation Internal AUI HUB port failure
When the condition is cleared, the LED
will return to green.
red/yellow,
blinking operation Both the condition indicated by the
blinking red (above) and the condition
indicated by the blinking green/yellow
(above) exist.
HUB red, solid self-test error detected on the HUB port
red, solid operation One or more:
Bit rate error detected
reversed receive polarity
serial port red, solid self-test error detected on the serial port
red, one blink,
returns to green operation One or more overrun, parity, or framing
errors.
Error Codes
The status LED blinks HEX error codes for fatal errors encountered during the self-test.
Errors are considered to be fatal if they prevent the RCS/3000 operating system from
starting. A RAM failure, for example, is a fatal error because it would prevent the operating
system from being loaded into RAM. When a fatal error is detected, the LED blinks a
sequence to indicate the category of the error. The LED continues to blink this error category
until the watchdog timer causes the board to reset (at least 1 ½ minutes). Following the reset,
self-test will run again and, unless the error is a transient error, will continue to fail and the
LED will continue to blink the error code.
The LED does not blink codes for nonfatal errors. Errors which do not prevent the operating
system from running, but may degrade the RCS/3000 capabilities, are non-fatal errors. Non-
fatal errors are not blinked, but are recorded in flash memory for troubleshooting by
customer service representatives.
