Chapter 2. Weight considerations: Model 092
expansion enclosure
Before you install, move, or perform service on a Model 092 expansion enclosure, you must be prepared
to handle the weight of the enclosure and its parts.
Safety notices and considerations
Important: Always read and follow the safety notices and instructions before you install, move, or service
the expansion enclosure and its parts. For more information, see “Danger and caution notices” on page 4.
• Do not exceed the specified maximum load of the rack where the enclosure is to be installed.
• Do not exceed any load limit of the building and flooring where the enclosure is to be installed.
• Always use a suitably rated mechanical lift or four persons when you are performing any of the following
tasks:
– Removing the expansion enclosure from its packing material
– Lifting and installing the expansion enclosure in the rack for the first time
– Reinstalling the expansion enclosure after you complete a service task (for example, replacing the
enclosure FRU).
• 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.
