Installing Boards and Components
Before installing a board, put on an ESD wrist strap 
or ESD gloves and ensure that the slot is correct. If 
it is difficult to insert a board, stop the operation.

Installing Boards
Filler panels must be installed in vacant slots to ensure good electromagnetic compatibility and meet dustproof 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 the same time is not allowed.
• Loosen the screws on a filler panel, and 
remove the filler panel. 
• Hold the ejector levers on the front panel 
of a board and raise them to form an angle 
of approximately 45 degrees with the front 
panel. Then, push the board gently along 
the guide rail until the board cannot go any 
further.
• Press the two ejector levers inwards until 
they cannot move further (Ensure that the 
self-locking latch of the ejector lever is 
locked into the panel when installing the 
system control board).
• Tighten the screws on the panel then 
install the other board.
