Status indicators (LEDs). The POWER indicator is lit when power is applied to the unit. BUSY is lit when the
system is powering up and when the unit is processing data and is unable to respond to new requests. ATTEN is
lit when there is a problem or condition requiring user intervention, such as a hardware problem, particularly
those involving the power supplies, fans, or disk drives.
