US Patent 7307836 Data storage device carrier and chassis

In one aspect, a data storage device carrier (10) has a bay in which a data storage device can be received. A light pipe (11) is provided for conveying light from one end of the carrier (10) to the other. A diffuser (16) is located near to but spaced from said other end of the light pipe (11) so as to spread and thereby magnify light emerging from said other end of the light pipe (11). In another aspect, a data storage device chassis (1) has a plurality of walls (3,4,20). At least some of the walls (3,4,20) have at least one runner (21) along at least part of the length of the wall (3,4,20) to define a plurality of bays in which data storage devices can be housed. At least one runner (21) has a transparent portion so as to be able to convey light from a light source (9) to the front of the chassis (1). In another aspect, a data storage device carrier (10 or chassis (1) has a strip of electroluminescent material (31) for displaying information.
