Installing the Cabinet
NOTE
•
For details about how to install the A63B assembly cabinet of the U32 enhanced subrack, see the A63B Cabinet
Quick Installation Guide.
•
For details about how to install the A66B assembly cabinet of the U32 enhanced subrack, see the A66B Cabinet
Quick Installation Guide.
•
In the scenario where the U32 enhanced subrack needs to adapt to ventilation mode A (air inlet from front - air outlet
from top/front) and ventilation mode C (air inlet from bottom - air outlet from top/front), to prevent the noise reduction
module of the subrack from blocking the bolt installation, remove the noise reduction module at the bottom of the
subrack before installing the cabinet. After the cabinet is installed, install the noise reduction module in the original
area. For details about the installation and removal of the noise reduction module, see sections "Removing the Noise
Reduction Module at the Bottom of an A63B Cabinet" and "Installing the Noise Reduction Module at the Bottom of an
A63B Cabinet."
•
If the U32 enhanced subrack needs to adapt to ventilation mode B (air inlet from front - air outlet from top), you only
need to re-install some of the noise reduction modules after the cabinet is installed. For details, see section
"Ventilation Mode B - air inlet from Front - air outlet from Top" in chapter "Installing Type-A Multi-Purpose Fiber
Management Cabinets" in this document.
•
If the U32 enhanced subrack needs to adapt to ventilation mode D (air inlet from front - air outlet from rear), to
prevent the air deflector of the subrack from blocking the bolt installation, remove the air deflector at the bottom of the
subrack before installing the cabinet. After the cabinet is installed, install the air deflector in the original area. For
details about the installation and removal of the air deflector, see sections "Removing the Air Deflector at the Bottom
of an A66B Cabinet" and "Installing the Air Deflector at the Bottom of an A66B Cabinet."
