Installing or replacing a Model 092 expansion enclosure in a rack
Use the following procedure to place an 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.
Important: The Model 092 expansion enclosure is heavy. Before you install the expansion enclosure in
the rack for the first 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 approximately 43 kg (95 lbs).
• Install the expansion enclosure in the lowest position in the rack. Figure 38 on page 55 shows an
example.

• Ensure that the drives are easily accessible. Avoid installing the Model 092 expansion enclosure in the
32U position above in the rack, when you relocate the rack. After the rack is installed, you can install
devices in the U32 position and above.
If you are reinstalling the expansion enclosure in the rack after you performed a service task (for example,
replacing the enclosure), you must also perform the following tasks:
• Reinstall all of the following parts:
– Cover
– Drives
– Fan modules
