The operational states of the option LEDs after the power-up diagnostic LED sequence is completed are described in
Table 4 . The states with a number in parenthesis are the number of pulses of 250 ms on, 250 ms off cycles, followed by
500 ms off, then repeating the cycle. Wait at least 2 seconds for the power-up diagnostic process to complete before
verifying LED states.


Power-Up Diagnostics
An LED test is performed each time the drive is powered up. The initial boot sequence may take several seconds. After
the LEDs have completed the diagnostic LED sequence, the option is successfully initialized. The LEDs then assume
operational conditions as shown in
Table 4 .
