service board installation area
Service boards or filler panels are inserted differently in the upper and lower
portions of a cabinet. When installing service boards or filler panels into upper-
portion slots, ensure that the ejector levers are on the left side of the front
panels. When installing service boards or filler panels into lower-portion slots,
ensure that the ejector levers are on the right side of the front panels. After
installing the boards, ensure that vacant slots are covered with filler panels for
heat dissipation.
