The IBBS200D/IBBS200T can be stacked only with the IBBS200D/IBBS200T or
TMC11H. When the IBBS200D/IBBS200T is stacked with the TMC11H, the TMC11H is
stacked on the IBBS200D/IBBS200T.
If auxiliary cabinets such as the IBBS200D/IBBS200T or TMC11H are required during an
initial site construction, the auxiliary cabinets are positioned on the left, and the primary
cabinet is positioned on the right. If both the battery cabinet and the TMC are required, the
battery cabinet is positioned on the left of the main cabinet, and the TMC is stacked on the
battery cabinet or positioned on the left of the battery cabinet.
Space must be reserved during an initial site construction for future capacity expansion. In
the capacity expansion scenario, the original cabinets are not relocated while new cabinets
are added only from left to right. In a special scenario, new cabinets can be added from
right to left.
A single APM30H+RFC cabinet group supports only one BBU. A triple-mode base station
is configured with two BBUs. The second BBU must be configured in the second APM30H
+RFC cabinet group. These principles are applied to a new or expansion scenario.
