Important Safety Warnings
ÅWARNING: Avoid Electrical Shocks. To avoid electrical shock, do not open the power supplies. There
are no user-serviceable parts inside.
To avoid electrical shock and harm to your eyes by laser light, do not open the DVD laser module. The
laser module should be serviced by service personnel only. Do not attempt to make any adjustment to the
laser unit. Refer to the label on the DVD for power requirements and wavelength. This product is a class I
laser product.
ÅWARNING: Removing and Replacing the Cover. For your safety, never remove the system side cover
without first disconnecting the power cord from the power outlet and removing any connection to a
telecommunications network. If a Power Protection Device is fitted to your system, you must shut down
your computer using its on/off switch, then remove the power cord before removing the system’s side
cover. Remove the Power Protection Device cables before any servicing operation. Always replace the
side cover before switching the system on again.
ÅWARNING: Battery Safety Information. There is a danger of explosion if the battery is incorrectly
installed. For your safety, never attempt to recharge, disassemble, or burn an old battery. Replace the
battery with the same or equivalent type, as recommended by the manufacturer.
The battery in this system is a lithium battery that does not contain any heavy metals. However, to protect
the environment, do not dispose of batteries in household waste. Return used batteries either to the shop
from which you bought them, to the dealer from whom you purchased your system, or to HP so that they
can either be recycled or disposed of in the correct way. Returned batteries will be accepted free of
charge.
ÅWARNING: Metallic particulates can be especially harmful around electronic equipment. This type of
contamination may enter the data center environment from a variety of sources, including, but not limited
to, raised floor tiles, worn air conditioning parts, heating ducts, rotor brushes in vacuum cleaners or
printer component wear. Because metallic particulates conduct electricity, they have an increased
potential for creating short circuits in electronic equipment. This problem is exaggerated by the
increasingly dense circuitry of any electronic equipment.
Over time, very fine whiskers of pure metal can form on electroplated zinc, cadmium, or tin surfaces. If
these whiskers are disturbed, they may break off and become airborne, possibly causing failures or
operational interruptions. For over 50 years, the electronics industry has been aware of the relatively rare,
but possible, threat posed by metallic particulate contamination. During recent years, a growing concern
has developed in computer rooms where these conductive contaminants are formed on the bottom of
some raised floor tiles.
Although this problem is relatively rare, it may be an issue within your computer room. Since metallic
contamination can cause permanent or intermittent failures on your electronic equipment,
Hewlett-Packard strongly recommends that your site be evaluated for metallic particulate contamination
before installation of electronic equipment.
ÅWARNING: Avoid Burn Injuries. Some parts inside the computer will be hot. Turn off and unplug the
system, then wait approximately three to five minutes for them to cool down before opening the system
access panels or touching internal components.

ÄCAUTION: Avoid Static Electricity. Static electricity can damage electronic components. Turn OFF all
equipment and disconnect the power cable before installing an accessory card. Don’t let your clothes
touch any accessory card. To equalize the static electricity when replacing an accessory card, rest the
accessory card bag on top of the system unit while you are removing the card from the bag. Handle the
card as little as possible and with care.
ÄCAUTION: Information on Ergonomic Issues. It is strongly recommended that you read the ergonomics
information, available in the “Working In Comfort” section of this manual, before using your system. You
can access more extensive ergonomics information at: www.hp.com/ergo
NOTE: Recycling Your System. HP has a strong commitment toward the environment. Your HP
system has been designed to respect the environment as much as possible. HP can also take back
your old system for recycling when it reaches the end of its useful life. HP has a product
take-back program in several countries. The collected equipment is sent to an HP recycling
facilities in Europe or the U.S.A. As many parts as possible are reused. The remainder is
recycled. Special care is taken for batteries and other potential toxic substances, these are
reduced into non-harmful components through special chemical processes. If you require more
details about the HP product take-back program, contact your local dealer or your nearest HP
Sales Office.

Power Consumption and Cooling
This information is based on primary power consumptions.
1. A typical configuration includes: 1 CPU, 4 GB RAM (4 x 1 GB), 700W power supply, 2 hard drives, 1
medium power AGP, and 1 optical drive.
2. A maximum configuration (fully loaded) includes: 2 CPUs, 32 GB RAM (8 x 4 GB), 700W power supply,

Environmental Specifications
Operating temperature and humidity ranges may vary depending on the installed mass storage
devices. High humidity levels can cause improper disk operation. Low humidity levels can
aggravate static electricity problems and cause excessive wear of the disk surface.

System Configuration
You will typically alter the system configuration only if you want to change the boot device or
change the console. This chapter covers:
■“Boot Console Handler (BCH)” on page 2-1
■“Firmware Upgrades” on page 2-9
Boot Console Handler (BCH)
You can configure the HP workstation c8000 system with The Boot Console Handler (BCH), the
user interface to the system firmware. The BCH:
■Lets the bootstrap code know which path (that is, which device) to boot from.
■Allows you to view and modify a set of specific system parameters.
■If you are satisfied with your system configuration, you do not need to perform any system
configuration.
Accessing the BCH
You can access the BCH through either:
■your system’s USB keyboard and graphics monitor by interrupting the normal boot process
■a serial console connection and terminal emulator.
Access via Keyboard and Graphics Monitor
When you boot your system, the boot process pauses and gives you 10 seconds to interrupt the
normal boot process. Perform the specified action to access the BCH. When you are finished,
reboot your system.
Access via Serial Console Connection
To access the BCH through a serial connection:
1. With the workstation turned off, connect the serial cable provided with your system or a
compatible cable to Serial Port A on the rear panel of the workstation, and to your remote
device.
NOTE: If your system has a plug-in serial card (installed in slot 6), connect to the card’s serial
port instead of to Serial Port A.
2. Disconnect all USB keyboards from the system.

System Configuration
3. Configure the terminal emulation software with these settings:
❏Baud rate: 9600
❏Bits: 8
❏Parity: None
❏Stop Bits: 1 (one)
❏Flow Control: XON/XOFF
4. Using the terminal emulation software, connect to the workstation with a direct connection.
5. Turn on the workstation. The system display is redirected to the serial console device.
Paths
All devices in the HP workstation c8000 are represented by paths in the BCH. To identify the
correct slot or disk drive, use the following tables.
