• At least three persons are required to move the enclosure while it is in the rack (if you are moving the
enclosure off the rails). Even after the drives, power supply units, secondary expander modules,
canisters, fans, and top cover are removed, the enclosure weighs approximately 43 kg (95 lbs).
• To maximize rack stability, always install the expansion enclosure in the lowest possible position in the
rack.
