Installing or replacing an expansion enclosure in a rack: 2145-92F
Use the following procedure to place the 2145-92F expansion enclosure in a rack during the installation
process. To complete some service tasks, you might also need to slide the enclosure back in to the rack.
About this task
Important: The 2145-92F expansion enclosure is heavy. Before you install the expansion enclosure in
the rack for the rst time or replace it in the rack to complete a service task, review and implement the
following tasks:
• Always use a suitably rated mechanical lift or four persons to raise the enclosure to install it in the rack.
Even after the drives, power supply units, secondary expander modules, canisters, fans, and top cover
are removed, the enclosure weighs 43 kg (95 lbs).
• Install the expansion enclosure in the lowest position in the rack. Figure 60 on page 61 shows an
example.

• Ensure that the drives are easily accessible. Avoid installing the 2145-92F expansion enclosure above
position 22U in the rack.
Procedure
1. Fully extend the left and right drawer sections from the rack to lock the rails in the extended position
( 1 in Figure 61 on page 62).
