V CAUTION!
● Because the PRIMERGY BX400 S1 system unit is large and
heavy, at least two people are needed to safely mount it in the
rack or remove it from the rack.
● Please observe the safety information and notes on rack installation
in the chapter "Important notes" on page 34.
● Before lifting the system unit, remove all server blades, storage
blades, connection blades, management blades, all power supply
units, fan units and dummy modules to reduce the weight.
● Only lift or carry the system unit by the handles on the long sides.
● Never lift or carry the system unit by the handles on the front or back.
Ê Make a note of the positions of the individual server blades and storage
blades, the connection blades, power supply units and fan modules in the
system unit for reinstallation.
