For easy updating of the firmware of the MPAI card, it features a round connector for
programming, labeled “P” on the front panel. This connector is not for current customer usage, it must
be used only for debug or updating or the MPAI card.
Indicators of the MPAI card
Each RJ45 includes a green and an orange LED indicator. Thus the single interfaces have two
LEDs each, and the double interfaces feature four LEDs each.
Figure 11 – MPAI card connectors and indicators
Each LED has four possible states: off, blinking slowly, blinking fast and on (lights
continuously). The combinations of these four states of LEDs have meanings that depend upon the
type and settings specific for each type of interface.
