This table contains status information about each shelf
in the GSX9000 Switch node. Shelves within the node can
can be configured before they are physically attached to
the node. Shelves that are attached may not be powered
or correctly configured as a slave. Therefore, it is possible
that a slave shelf can not be detected, and is absent.
The value of sonusNodeShelfAdmnStatus indicates the availability
of this shelf. If the sonusNodeShelfAdmnStatus value for the
index shelf does not indicate a status value of 'accepted',
then this status table is not available.
