Device Identification

When more than one CPU blade of the same type is installed, use the ID lamp to identify the CPU
blade requiring maintenance.
The ID lamp is located on the CPU blade installed in the Blade Enclosure.
The ID lamp also blinks blue when software commands from the management PC on the network
are used. In addition, pressing the ID switch on the CPU blade illuminates the ID lamp.
