When the HSD05 array controller boots, red indicator DS1 blinks for 15 seconds
before it shuts off. If this indicator blinks for more than 15 seconds, it indicates
that the onboard diagnostics have found a fault.
The fault code is read out as a two-digit error code on the indicators; each digit
of the code is indicated by the number of times the indicator blinks. The first
digit of the code is separated from the second digit by a one-second pause. A
two-second pause separates the error code from its next repetition. This code is
repeated until reset by a power-off of the HSD05 array controller.
Table 3–1 lists the serviceable error codes and the associated problem. For
all other error codes, recheck the integrity of all bus terminator and cable
connections and verify that all shelf SBBs are seated properly. If these actions do
not resolve the problem, replace the HSD05 array controller.
