communication error on one of its ports or a backplane error. APP Amber
Off The MVI46-DFCM is working normally.
On The LED is on when the module is performing a write
operation on the backplane. BP ACT Amber
Off The LED is off when the module is performing a read
operation on the backplane. Under normal operation, the LED
should blink rapidly on and off.

the LED remains red for over 10 seconds, the program has
probably halted. Turn off the power to the rack, remove the
card from the rack and visually inspect the module. Re-insert
the card and turn on the power to the rack to restart the
module's program.
Off The battery voltage is OK and functioning. BAT Red
On The battery voltage is low or battery is not present. Allow
battery to charge by keeping module plugged into rack for 24
hours. If BAT LED still does not go off, contact ProSoft
Technology, as this is not a user serviceable item.
During module configuration, the OK LED will be red and the APP and BP ACT
LEDs will be on. If the LEDs are latched in this mode for a long period of time,
look at the configuration error words in the configuration request block. The
structure of the block is as shown below:
