Viewing system components
The System topic enables you to see information about each enclosure and its physical components in front, rear, and tabular
views. Components vary by enclosure model.
NOTE:
If an attached enclosure or component is unsupported, the system health shows as Degraded and the unsupported
component's health shows as Fault. Hover the cursor over the faulty component to see why it is unsupported and the
recommended action to take. For more information, review the event log.
Front view
The Front tab shows the front of all enclosures in a graphical view.
For each enclosure, the front view shows the enclosure ID and other information. For each drawer, the front view shows
the drawer ID and other information. To see more information about an enclosure, drawer, or disks, hover the cursor over an
enclosure ear, drawer, or a disk. To illuminate a locator LED for an enclosure or disk, select one or more components and click
Turn On LEDs. To turn off individual locator LEDs, select the components and click Turn Off LEDs. To turn off all locator
LEDs, ensure that no components are selected and click Turn Off LEDs.
