To indicate the presence of the PEM, a PEM presence signal is grounded by the PEM body. A Blue Hot-Swap
LED and a Hot-Swap Push Button provide Hot-Swap functionality.
A red (power failure) and a green (OK) LED provide status indication. Each of the four redundant
power-feeds supply power to a separate part of the ATCA Backplane.
