2 Installing Fan powered box
Determine the mounting direction of the
Fan powered box and push it into the slot.
Press the button on each side of the Fan powered box and push
the assembly until it is fully seated in the slot. After releasing the
buttons, check whether they are restored to their original positions.
If they are not, withdraw the Fan powered box, restore the buttons
to their original positions, and then install the Fan powered box
again.
NOTE
A yellow-green button is located on the
left and right sides of a Fan powered
box. You must press these two buttons
to completely plug the Fan powered box
into the subrack or to remove it from the
slot.

The air flows in the upper and lower portions of a cabinet are in opposite directions, so the Fan powered box assemblies at
the top and bottom of the cabinet are installed differently. Four labels are located on the Fan powered box: two on the top
surface and two on the bottom. One of the labels, a mounting direction label, indicates the mounting direction of the Fan
powered box. Another mounting direction label is present on the air blocking panel that covers a vacant Fan powered box
slot or inside the Fan powered box slot. When installing a Fan powered box in the upper portion of a cabinet, ensure that the
mounting direction label on the right of the Fan powered box surface faces upward. When installing a Fan powered box in
the lower portion of a cabinet, ensure that the mounting direction label on the left of the Fan powered box surface faces
upward.
The Fan powered box is designed for
easy installation. If you feel a blockage
when inserting a Fan powered box into a
slot, remove it and check whether it was
inserted correctly. Do not use force to
insert the Fan powered box.
