Disk Tray 1-8

Eight disk trays for installing hard drives.

Tray Open Button

Each disk tray has a Tray Open Button, which serves the following purposes:

• Indicates whether the disk tray is locked. When the button's groove is horizontal, the disk tray is locked. When it is vertical, the disk tray is open.
• Enables you to lock/unlock the disk tray, by using one of the disk tray keys to turn the button until its groove is horizontal/vertical.
• Enables you to open the disk tray. Upon pressing the button, the outer panel of the disk tray (visible in the preceding diagram) becomes a lever that can be used to pull the disk tray out of the appliance.
