The Hardware page provides status and settings for shelf components, including the power supplies, fans, and batteries.
The available components depend on the type of shelf:
-
Drive shelf — Contains a set of drives, power/fan canisters, input/output modules (IOMs), and other supporting components in a single shelf.
-
Controller shelf — Contains a set of drives, one or two controller canisters, power/fan canisters, and other supporting components in a single shelf.
-
Select Hardware.

Select the drop-down list for the Controller Shelf or Drive Shelf, and then select View Settings.
The Shelf Components Settings dialog box opens, with tabs that show the status and settings related to the shelf components. Depending on the type of shelf selected, some tabs described in the table might not appear.
Tab Description Shelf
The Shelf tab shows the following properties:
