The first two groups, sunHwMonProductGroup and sunHwMonProductChassisGroup, define scalar MIB objects that provide information regarding the Sun Server details such as Part number, Manufacturer, and so on. These groups are:
sunHwMonProductGroup is a scalar group that provides general product details about the Sun server or server module, such as the part number, type, name, and serial number.
sunHwMonProductChassisGroup is a scalar group that provides details about the Sun server's chassis or the chassis into which the Sun server has been inserted.
Note - sunHwMonProductChassisGroup is populated only on server modules, where it is relevant.
