The IBM 7314-G30 is an IBM signature Raven Black I/O drawer made up of two half-width drawers, each housing six PCI adapter slots and two power supplies. The dominant feature of the bezel is the circular openings, venting the power supplies. Backing panels replace two of the four perforated openings if only one half-drawer is installed. Diagnostic LEDs are located on the front of the bezel to display system status. A service slot and adapter are also integrated in the top of the front bezel, allowing critical system information to be readily available when needed. The bezel is easily removed by actuating the blue touch-point latches on either side to service or replace the power supplies in the rack drawer. Power supplies cam out using the levers located behind the semicircular bezel protrusions for easy hot-swap maintenance.
