3.5 Connecting Racks
To use additional expansion racks, connect additional racks to the existing rack (base rack or
expansion rack ).
■ Confirming components
Confirm that all components of the connection kit that need to be supplied with an expansion rack
have been delivered (see the table below).
Also, prepare the necessary tools:
・ Phillips screwdrivers (No. 2 and No. 3 bits)
・ Hexagon wrench (M12 retaining screws for the top cover: Socket size 8)
・ Spanner or box wrench (M12 screws for upper connection: Socket size 19)
Also, prepare a stepladder because some of the work will need to be performed at height.
・ Before connecting racks, turn off the power to the server and peripherals and
disconnect the power cables from the outlet.
Otherwise, there may be electric shock or failure of the equipment.
・ To prevent injury, ensure that at least two persons perform the rack connection
work.
Otherwise, injury may result.
・ You may get on a stepladder when working on the upper part of the rack.
Be careful not to fall from the stepladder.
・ Do not put your foot on the racks when connecting racks.
