IMB Network Cabinet
The IMB network cabinet supports the IP31 protection rating, and can be wall mounted indoors,
in the corridor, and in the weak current well.
A small-sized IMB network cabinet has a compact structure and occupies only a little installation
space. In addition, it can be installed on an uneven wall with an undulation smaller than 10 mm,
so it has low requirements on site selection.
The IMB network cabinet provides a 3 U installation space for user devices. The internal 2 U
installation space is for an ATN device and the external 1 U installation space is for a power
supply device. Figure 4-20 and Figure 4-21 show the appearance and structure of an IMB
network cabinet.
