3.5 Board Hot Swap and Installation
Because of the high-density pinout of the hard-metric connector, some precautions must be taken when
connecting or disconnecting a board to/from a backplane:
1 Rail guides must be installed on the enclosure to slide the board to the backplane.
2 Do not force the board if there is mechanical resistance while inserting the board.
3 Screw the front plate to the enclosure to firmly attach the board to its enclosure.
4 Use ejector handles to disconnect and extract the board from its enclosure.
