Utilizing invertible alphanumeric slot identifiers on devices

A device, comprising:

• data storage circuitry:
• a housing that holds the data storage circuitry;
• and
• an alphanumeric marking on the housing, the device being constructed and arranged to insert into a first slot defined by a data storage chassis and electrically connect with an interconnect supported by the chassis during a first operating time and insert into a second slot defined by the data storage chassis and electrically connect with the interconnect during a second operating time, the alphanumeric marking displaying the first alphanumeric slot identifier when the device is inserted into the first slot and displaying the second alphanumeric slot identifier when the device is inserted into the second slot;
• wherein the alphanumeric marking of the device displays the first alphanumeric slot identifier when right side up and displays the second alphanumeric slot identifier when upside down.

Data storage equipment, comprising:

• a chassis that defines a first slot which is identified by a first alphanumeric slot identifier and a second slot which is identified by a second alphanumeric slot identifier;
• an interconnect supported by the chassis;
• a device constructed and arranged to perform data storage operations when inserted into the first slot and electrically connected with the interconnect during a first operating time and when inserted into the second slot and electrically connected with the interconnect during a second operating time, the device showing an alphanumeric marking that displays the first alphanumeric slot identifier when the device is inserted into the first slot and displays the second alphanumeric slot identifier when the device is inserted into the second slot;
• a first chassis marker disposed adjacent the first slot and displaying the first alphanumeric slot identifier;
• and
• a second chassis marker disposed adjacent the second slot and displaying the second alphanumeric slot identifier;
• and
• wherein the alphanumeric marking shown by the device matches the first chassis marker when device is right side up and matches the second chassis marker when the device is upside down.
