On The MVI56-DFCMR is working normally. APP Amber
Off The MVI56-DFCMR module program has recognized a
communication error on one of its ports.
On The LED is on when the module is performing a write
operation on the backplane. BP ACT Amber

operation on the backplane. Under normal operation, the LED
should blink rapidly on and off.

plugged into the rack.
Green The module is operating normally.
OK Red /
Green
Red The program has detected an error or is being configured. If
the LED remains red for over 10 seconds, the program has
probably halted. Remove the card from the rack and re-insert
the card 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 will be red and the APP and BP ACT LEDs
are on.
If the APP, BP ACT and OK LEDs blink at a rate of every one-second, this
indicates a serious problem with the module. Call ProSoft Technology support to
arrange for repairs.
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 shown in the following table.
