Electronic device having keying mechanisms for a drive carrier and a drive cage

A drive cage of an electronic device, comprising:

• a drive bay;
• a plurality of first guide members and a plurality of second guide members disposed alternating to each other along a width of the drive cage, wherein each first guide member of the plurality of first guide members has a first length and each second guide member of the plurality of second guide members has a second length smaller than the first length;
• and
• a keying flange inside the drive bay, wherein the keying flange is positioned between each first and second guide members and disposed behind the first and second guide members,
• wherein, when a drive carrier of the electronic device is arranged in the drive bay in a first orientation, the keying flange is aligned with a keying protrusion of the drive carrier to prevent a media drive carried by the drive carrier, to be coupled to a backplane circuit board of the electronic device, and
• wherein, when the drive carrier is arranged in the drive bay in a second orientation that is opposite to the first orientation, the keying flange is aligned away from the keying protrusion to allow the media drive to be coupled to the backplane circuit board.

A method for assembling an electronic device, comprising:

• positioning a drive carrier of the electronic device, in one of a first orientation or a second orientation that is opposite to the first orientation;
• and
• inserting the drive carrier in a drive bay of a plurality of drive bays of a drive cage of the electronic device to arrange the drive carrier in the drive cage, such that:
• when the drive carrier is positioned in the first orientation, a keying protrusion of the drive carrier is aligned with a keying flange of the drive cage to prevent a media drive to be coupled to a backplane circuit board of the electronic device;
• when the drive carrier is positioned in the second orientation, the keying protrusion is aligned away from the keying flange to allow the media drive to be coupled to the backplane circuit board;
• when the drive carrier is inserted along a first drive bay of the plurality of drive bays, a first guide member and a second guide member of the drive cage defining the first drive bay and the second guide member and an adjacent first guide member defining a second drive bay among the plurality of drive bays allow a first side structure and a second side structure of the drive carrier to move along the first and second drive bays and install the drive carrier to the drive cage;
• and
• when the drive carrier is inserted along the second drive bay, the adjacent first guide member of the second drive bay and a third drive bay of the plurality of drive bays engages with the first and second side structures of the drive carrier to restrict the drive carrier from moving further along the second and third drive bays and prevent installation of the drive carrier to the drive cage.
