Precautions for Installation in Different Ventilation Modes

6.1

Ventilation Mode A: Air Inlet from Front - Air Outlet from Top/Front

NOTE
• The default ventilation mode of the U32 enhanced subrack installed in the A63B cabinet is
ventilation mode A (air inlet from front - air outlet from top/front). The type-A multi-purpose fiber
management cabinet does not need to be installed.
• For details about how to install an A63B cabinet with U32 enhanced subracks, see the A63B
Cabinet Quick Installation Guide. 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, re-install the noise reduction module.
For details, see section "Installing Cabinets" in this document.
