1.3.4 Drive Carrier Module
The Drive Carrier module comprises a hard disk mounted in a carrier. Each drive bay will house a single
1.0 inch high, 3.5 inch disk drive in its carrier.
Each disk drive is enclosed in a die-cast aluminum carrier which provides excellent thermal conduction,
radio frequency and electro-magnetic induction protection and affords the drive maximum physical
protection.
The front cap also supports an ergonomic handle which provides the following functions:
• Camming of carrier into and out of drive bays.
• Positive 'spring loading' of the drive/backplane connector.
• An anti-tamper lock operated by a torx socket type key.
