Description: This is different from the MIB II sysLocation variable as it contains only the location area and does not describe the precise location. This contains a display string that defines the area in which the unit is installed. Location is defined by a set of three objects: 'Area', 'Rack', and 'Shelf'. These location objects cannot be determined by the unit itself, but can only be determined by the network manager. It is available to the unit for display on a front panel. Display of the location on the front panel is useful in validating the configuration established by the network manager. The unit should only allow this object to be set when it is in the 'configuration' mode. Once the Location Area has been set, it should be kept in non-volatile memory.
