Enclosure Chassis; Power Cooling Module (Pcm) Detail - Seagate RealStor 5005 Series Hardware Installation

IMPORTANT: RBOD/EBOD configurations:
• When the expansion module shown above
storage, its middle HD mini-SAS expansion port ("B") is disabled by the firmware. See also
• The Ethernet port on the expansion module is not used in RBOD/EBOD configurations, and is disabled.
Power cooling module
Figure 13 shows the power cooling module (PCM) used in controller enclosures and optional expansion enclosures. The PCM
includes integrated cooling fans. The example shows a PCM oriented for use in the left PCM slot of the enclosure rear panel.

Enclosure chassis

The 2U chassis consists of a sheet metal enclosure with an integrated midplane PCB and module runner system. Each
enclosure is comprised of sheet steel that is bonded together using rivets, welding, and other forced contact methods.
The metal surfaces are free from non-conductive coatings and paint.
NOTE: Supported 2U chassis form factors used for configuring RBODs and EBODs:
• 2U12 chassis configured with 12 LFF disks: see
• 2U24 chassis configured with 24 SFF disks: see
• 2U12 empty chassis with midplane: see
• 2U24 empty chassis with midplane: see
• The chassis has a 19-inch rack mounting that enables it to be installed onto standard 19-inch racks and uses two EIA
units of rack space (3.5") for a 2U enclosure.
• The midplane PCB can support either 12 or 24 disk drive connections.
• There are either 12 or 24 drive slots at the front of the enclosure, in horizontal (12) or vertical (24) orientation, as
defined by the enclosure variant. See also
carrier module that can hold these drive types, dependent upon the enclosure type:
2U12 enclosure: 12 low profile (1" high) 3.5" LFF disk drives, held horizontally.

2U24 enclosure: 24 low profile (5/8" high) 2.5" LFF disk drives, held vertically.
