Specifications
This section provides site specifications for the storage expansion enclosure. Before
installing a storage expansion enclosure, you must either verify that your planned
installation site meets these requirements, or prepare the site so that it does meet
these requirements. Preparations might involve meeting area requirements,
environmental requirements, and electrical requirements for storage expansion
enclosure installation, service, and operation.
Area requirements
The floor space at the installation site must provide enough strength to support the
weight of the storage subsystem and associated equipment; sufficient space to
install, operate, and service the storage subsystem; and sufficient ventilation to
provide a free flow of air to the unit.
Dimensions
Figure 6 shows the dimensions of the EXP395, which conforms to the 19-inch rack
standard.
Weight
The total weight of the storage expansion enclosure depends on the number of
components installed. Table 5 lists the maximum, empty, and shipping weights for
the storage subsystem in different configurations. Table 6 lists the weight of each
component.
