Enclosure indicators provide an overview of the enclosure status. The
enclosure indicators are on the left end cap of the enclosure.

the enclosure status. The product name, machine type-model, serial number, and type of enclosure
(control or expansion) are shown on the left end cap. When multiple enclosures are in a machine room
or rack, the serial number is used to identify the enclosure being referenced. Figure 1. Left enclosure end cap
