The air flows in the upper and lower portions of a cabinet are in opposite directions, so the fan tray assemblies
at the top and bottom of the cabinet are installed differently. Four labels are located on the fan tray assembly:
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 tray assembly. Another mounting direction label is present on the air blocking
panel that covers a vacant fan tray assembly slot or inside the fan tray assembly slot. W hen installing a fan
tray assembly in the upper portion of a cabinet, ensure that the mounting direction label on the right of the fan
tray assembly surface faces upward. W hen installing a fan tray assembly in the lower portion of a cabinet,
ensure that the mounting direction label on the left of the fan tray assembly surface faces upward.
NOTE
•
The fan tray assembly is designed for easy installation. If you feel a blockage when inserting a fan tray
assembly into a slot, remove it and check whether it was inserted correctly. Do not use force to insert the
fan tray assembly.
•
The fan tray assembly is heavy. W hen removing the fan tray assembly, hold it with both hands to prevent it
from falling off.
