The illustration below shows the system features that are accessible from the front panel with the disk access door open.
For more information about front panel controls and indicators, see "About the Status and Control Panel".
Access to the system's internal disk drives is through a large hinged door at the front of the system. The disk access door features a key lock for added security.
When the key is in the vertical position, the door is unlocked. Make sure that the key is in this position before you close the door. To lock the door, simply turn the key 90 degrees counterclockwise and remove the key. This same key also controls the front panel keyswitch.
