A message is returned reporting that either the PTC was successfully turned on
successfully with no problem or an overcurrent condition was sensed. This test is
repeated again 5 seconds later.
TN2181 and TN2224 boards carry a Protected Power Feed (PPF) relays, one for
each port. Therefore this will be a Protected Power Feed restoral test. The test
procedure and its response is same as that of EPF. One of differences between
EFP and PPF is that, if the port goes into a overcurrent state, PPF does not report
this change of state because it is a transient state which will not last more than
50ms. If the over current persists the power will be shut off automatically and an
EPF_off_overcurrent message is sent uplink.
