Powering up
When applying power to the SMX, it undergoes a start-up self testing sequence:
1 . 3U, 4U, and 5U models — All buttons flash amber, then green, red, and
amber, and then extinguish.
2U models — All buttons flash green, red, and amber, and then extinguish.
2 . The two LED’s light green to indicate power is present to main and I/O
boards.
N The sequence also occurs when the unit restarts after firmware uploads.
