4.7.3. Checking the Status of the DGX Station SSDs
LEDs on the DGX Station SSDs indicate the status of the SSDs. The SSDs are mounted inside
the DGX Station and are visible only when the side panel that covers the SSDs is removed.
1. Remove the side panel on the left of the DGX Station when viewed from the rear.
a). Push the button on the left side of the DGX Station back panel to release the panel.
b). Lift the panel to remove it.
CAUTION:
To prevent damage from electrostatic discharge, avoid touching any of the
components inside the DGX Station other than any components that you are replacing
or servicing.
2. Examine each SSD to determine its status from the state of the LED on the SSD.
