3.2 COM Express and Memory
The COM Express and the memory module are preinstalled and should not be removed or exchanged by the
user.
3.3 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 frontplate to the enclosure to firmly attach the board to its enclosure.
4 Use ejector handles to disconnect and extract the board from its enclosure.
3.3.1 Installing the Board in the Chassis
To install a board in a chassis:
1 Remove the filler panel of the slot or see "Removing the Board" below.
2 Ensure the board is configured properly.
3 Carefully align the PCB edges in the bottom and top card guide.
4 Insert the board in the system until it makes contact with the backplane connectors.
5 Using both ejector handles, engage the board in the backplane connectors until both ejectors are locked.
6 Fasten screws at the top and bottom of the faceplate.
WARNING
Removing memory and/or Com Express modules may leave the board inoperable or
my even damage the board.
WARNING
Always use a grounding wrist wrap before installing or removing the board from a
chassis.
