Make sure you are wearing a grounding wrist strap that is attached to the
metal of the enclosure before you continue. The boards are sensitive to
electrostatic discharge. Do not handle boards unless you are properly
grounded.
11. Locate the new board you are installing.
12. Remove the board from the antistatic bag.
13. Insert the board into the slot. Make sure the slot cover aligns correctly.
14. Push the board into the slot. Make sure the board is seated completely in
the slot.

Do not run the LANserver EX3 without the board retainer bar. The board
retainer bar ensures that the boards are seated properly in their slots.
Running the LANserver EX3 without the board retainer bar can cause
intermittent problems.
16. Reinstall the board retainer bar. Make sure the drive controller boards are
vertical. They must be in the left groove on the board hold-down arm
when looking at the LANserver EX3 from the front.
17. Align the board retainer bar and replace the board retainer bar screw.
