Ventilation Mode B: Air Inlet from Front - Air Outlet from Top

NOTE
• To install a U32 enhanced subrack of ventilation mode B (air inlet from front - air outlet
from top) in an A63B cabinet, type-A multi-purpose fiber management cabinets need to
be installed.
• For details about how to install the A63B cabinet of the U32 enhanced subrack, 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 a cabinet. After the cabinet is installed, install the
noise reduction module in the original area. For details, see section "Installing the
Cabinet" in this document.
• For details about how to install a type-A multi-purpose fiber management cabinet, see
