MFAT Electronic Power Feed (#56)
The software requests that the EPF be turned on for a given port. The hardware then attempts
to turn on that port’s station power unit. If no current is drawn, the station is probably not
connected. If an overcurrent condition is sensed (too much current is drawn), a short may exist
in the loop, or the voice terminal may be defective. The test results in a message indicating that
either the EPF was turned on successfully with no problems, or an overcurrent condition exists.
This test is repeated after a 5 second delay. If either test is not successful, the test aborts.
Although this test will never actually return a fail result (except for the internal system error), an
error type 257 entry will be made in the error log when the test has completed if the overcurrent
case is detected by the hardware.
FAIL Battery Feed test failed. This port is out-of-service.
1. Other ports on this circuit pack are not affected. Place user on a
different port, if available, until a replacement circuit pack can be
obtained.
2. Replace circuit pack when available.
PASS Battery Feed test passed. Current flow is properly detected for this port.
1. If users are reporting problems, examine connections to the port.

BOARD
The test could not relate the internal ID to the port (no board). This could
be due to incorrect translations, no board is inserted, an incorrect board
is inserted, or an insane board is inserted.
1. Check to ensure that the board translations are correct. Use list
config, and resolve any problems that are found.
2. If the board was found to be inserted correctly, enter busyout
board location.
3. Enter the reset board location command.
4. Enter the release board location command.
5. Enter test board location long. This should re-establish the
linkage between the internal ID and the port. If this is not the case,
check to ensure that there is a valid board inserted.
