on the backplane.

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.
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.
