Laser Safety Statement (For U.S.A. Only)

(For computers with a CD ROM disk drive installed.)

The CD ROM mass storage system is certi ed as a Class 1 laser product under the U.S. Department of Health and Human services (DHHS) Radiation Performance Standard according to the Radiation Control for Health and Safety Act of 1968.

This means that the mass storage system do es not produce hazardous laser radiation. Since laser light emitted inside the mass storage system is

completely con ned within protective housings and external covers, the laser beam cannot escape from the machine during any phase of user operation.

Warning		Use of controls, adjustments, or performing procedures
		different from those specified in this manual may result in
		hazardous invisible laser radiation exposure. None of the
		mechanisms within the mass storage system contain customer
		or field-replaceable parts.
		The CD ROM drive becomes a Class 3B laser mechanism
		when disassembled. If the CD ROM drive is disassembled,
		exposure to the invisible laser beam and hazardous invisible
		laser radiation could result in blindness. Do NOT disassemble
		the CD ROM drive for any reason.

The system unit is intended for deskside placement.

Figure 1-1. The System Unit

1-2 Your HP Apollo 9000 Model 750 Computer

The Power On/Standby Switch

The switch that you use to turn on your HP Apollo 9000 Model 750 is located on the in the front of the system unit's right \shoulder." (See Figure 1-2.) This switch is actually a power on/standby switch. It is not the same as a power switch.

When you attach the power cable to the connector on the power supply and plug that cable into a power source, electric power is available from the power supply. When you turn on the power on/standby switch, that electrical power is distributed to the rest of the system unit.

Warning	Do not assume that all power to the computer is off just
	because the power on/standby switch has been turned off.
	To completely remove power from you computer, unplug the
	power cable from the power outlet and disconnect that cable
	from the power supply.

Understanding the LEDs

In the front of the system unit's center section is a hinged cover. When the cover is closed, ve LEDs can be viewed through small \windo ws". Beside each window is a symbol indicating the meaning associated with the activity of each LED. Table 1-1 describes the activit y of the lights when the HP-UX operating system is running on your computer.

Table 1-1. LED Symbols and Their Meanings

Symbol	LED Activity	Meaning
	On/O	Power on/standby

	Flashing	Transmitting to LAN

	Flashing	Receiving from LAN

	Flashing	Disk activit y

		Slow ash	System \heartbeat"

Note	If you have been working on your system successfully , and the
	\heartbeat" LED remains o or on for a long period of time,
	it may mean that your system is \h ung" (incapable of further
	processing). See Chapter 6 for suggestions on ho w to deal with
	this condition.

1-4 Your HP Apollo 9000 Model 750 Computer

	Figure 1-3. LED Windows
Note	It takes a substantial amount of time (2|5 minutes) for your
	computer to start the HP-UX operating system. During this
	time, the behavior of these LED indicators (and the others
	hidden behind the cover) is not controlled by HP-UX. Do not
	interpret the behavior of the LEDS as illustrated by Table 1-1
	until after HP-UX has nished booting.
