Power Cooling Module (PCM)
Power Supply Unit (PSU)
Fan Cooling Module (FCM)
SBB controller module (maximum weight)
SBB expansion module
RBOD enclosure (fully populated with

NOTE:
• Weights shown are nominal, and subject to variances.
• 2U rail kits add between 2.8 kg (6.2 lb) and 3.4 kg (7.4 lb) to the aggregate enclosure weight. 5U84 rail kits add
significantly more weight.
• Weights may vary due to different controller modules, IOMs, and power supplies; and differing calibrations between
scales.
Weights may also vary due to the actual number and type of disk drives (SAS or SSD) and air management modules
installed.
