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.
