Huawei OSN1800 I and OSN1800 II support both AC and DC pluggable power modules. However, slots for AC and DC power modules are different. DC modules typically use dedicated PIU power slots, while AC modules occupy service slots normally. Therefore, when purchase or install OSN1800 chassis, the following aspects of power module need to be noted.

PIU and APIU boards cannot be installed on the same chassis. Install the PIU board only on a DC power-supply chassis and install the APIU board only on an AC power-supply chassis.

2, OSN1800 I/II AC power APIU, actually consists of two pluggable AC power modules and one power tray. When customers purchase AC power supply modules separately, they need to make sure to include the power tray, as the power supply modules cannot be plugged directly into the Chassis.

The APIU board occupies two slots. The pins on the board are located on the upper part of the board; therefore, the board is inserted into the upper slot between the two slots.
