The GET_HOST_PWR_MICRO_VER command toggles the power button of server. For this command to parse correctly, the GET_HOST_PWR_MICRO_VER command must appear within a SERVER_INFO command block, and SERVER_INFO must be set to read.
Example:
<RIBCL VERSION="2.0">
<LOGIN USER_LOGIN="admin" PASSWORD="admin123">
<SERVER_INFO MODE="read">
<GET_HOST_PWR_MICRO_VER/>
</SERVER_INFO>
</LOGIN>
</RIBCL>
