CRU/component 2U12 (kg/lb) 2U24 (kg/lb) 5U84 (kg/lb)
EBOD enclosure (fully populated with
modules: maximum weight)
28/62 25/55 130/287
NOTE:
● Weights shown are nominal, and subject to variances.
● Weights may vary due to different controller modules, IOMs, and power supplies; and differing calibrations between
scales.
● Weights may also vary due to the number and type of disk drives (SAS or SSD) installed.
