4.2 LED Status Indicators
The LEDs indicate the module's operating status as follows:
ProSoft
Module Color Status Indication
On Data is being transferred between the module and a remote
terminal using the Configuration/Debug port. CFG Green
Off No data is being transferred on the Configuration/Debug port.
On Data is being transferred by the module on Port 1. P1 Green
Off No data is being transferred on the port.
On Data is being transferred by the module on Port 2 P2 Green
Off No data is being transferred on the port.
On The MVI module is working normally. APP Amber
Off The MVI 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
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.
Off The card is not receiving any power and is not securely 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. Power down and remove the card from the rack and re-
insert the card, then power up the rack.
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 the factory, 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.
4.3 Clearing a Fault Condition
Typically, if the OK LED on the front of the module turns red for more than ten
seconds, a hardware problem has been detected in the module, or the program
has exited.
To clear the condition, follow these steps:
1
Turn off power to the rack
2 Remove the card from the rack
3 Verify that all jumpers are set correctly
