The system’s Power button is beside the keyswitch and is controlled by the keyswitch settings. For more information about the keyswitch positions, see “Keyswitch Settings” on page 9.

The system’s standard front panel and controls are illustrated in the figure below. An optional tape drive is available in place of the DVD-ROM. For more information about using the DVD-ROM drive, or the optional tape drive (if installed), see Chapter 5.

Opening the system’s front doors provides access to the system’s hot-pluggable internal disk drives.

Systems may be configured with one or two power supplies, and one or two disk drives either of which is accessible when the system front doors are open. Each power supply has an LED that displays the AC power, DC power, and fault status of the supply. Only qualified service providers should access the power supplies. See “Power Supply Failure” on page 195 for operational details of the LEDs.

Each disk drive has an LED indicating when lit steadily that the drive is present, and if the LED is blinking that there is activity on the disk. For additional information see “About Power Supplies” on page 95.
