If the MA5800-X7 subrack is installed in a subrack with B-T airflow, you are advised to add
an air deflector to the subrack so that the hot air does not direct flow to the MA5800-X7.
When 2 U space is reserved at the air inlet and 3 U space is reserved at the air outlet, the
cabinet panels will have less impact on the heat dissipation of the MA5800-X7.

• Reserve 10 U space between the devices or add a 3 U air deflector to redirect air flows to
minimize the mutual heat dissipation impacts on the devices.
• Reserve at least 4 U space when you route fibers or install other passive devices to facilitate
subsequent air inlet or dust filter cleaning.
