CAUTION
Wear ESD wrist straps or ESD gloves before installing or removing a
board.
Filler panels must be installed in vacant slots to ensure good
electromagnetic compatibility and meet dust-proof and heat dissipation
requirements.
The filler panel in a slot can be removed only before you insert an
interface board into the slot. Removing multiple filler panels and then
inserting multiple interface boards at a time is not allowed.
When sliding a board into a slot along guide rails, press the front panel
of the board with your thumbs, and push the board until it cannot move
forward. Then, fasten the ejector levers.
Hold the ejector levers on the panel with both hands, and turn them
1
outward until they make an angle of 45 degrees with the panel.
Push the board along guide rails into the slot until it cannot move
2
forward.
Lower the ejector levers and push them inward until they cannot
3
move forward. (When installing a main control board, ensure that
the latches of the ejector levers are locked into the panel.)
4 Use a Phillips screwdriver to fasten the captive screws clockwise on
both sides of the panel.
