communication error between the module and the processor.
BP ACT Amber On The LED is on when the module is performing a write
operation on the backplane.
Off The LED is off when the module is performing a read

OK Red/
Green
Off The card is not receiving any power and is not securely
plugged into the rack.
Green The module is operating normally.
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.
BAT Red Off The battery voltage is OK and functioning.
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 BP ACT LED will be
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.
