Installing and Removing FRUs

The Sun StorEdge 3900 and 6900 series storage systems are preconfigured with all
the FRUs installed in the configuration that the customer specified. This chapter
describes the general instructions about how to install and remove a FRU, the
default configuration settings for the Sun StorEdge 3900 and 6900 Series storage
systems, and the placement of the FRUs in the storage system.
The procedures to configure or modify the configuration of the FRUs that have a
software component are described in the chapter associated with the specific FRU.
Caution – FRUs in the storage system must be loaded from the bottom to the top to
keep the storage system center of gravity as low as possible. When servicing the
storage system, remove only one FRU from the storage system at a time. If possible,
remove FRUs from top to bottom to prevent raising the center of gravity of the
storage system.
