Serial number and COA label location
Each workstation has two unique serial number labels (1) and a Certificate of Authentication (COA) label
(2) (for Windows preinstalled workstations only). In general, the serial number labels can be found on
the top panel or on the side of the workstation and at the rear of the workstation. Keep this number
available when contacting customer service for assistance.
Figure 1-5 Serial number and COA label location
Maximizing the airflow
●Keep your workstation in an area where the airflow is not obstructed.
●Keep the workstation off of surfaces where dust can gather.
●Keep the front of the workstation clear of any obstruction.
●Remove any dust on the front panel (vent area) and the rear fans with a small vacuum, compressed
air, or dust rag.
●Keep the back of the workstation at least 0.15m (6 in.) away from a wall or other obstruction.

This product is in compliance with US executive order 13221, WOL (wake on LAN) disabled.
NOTE: When you power down your workstation with the power button on the front panel, the power
consumption falls below 10W. To reach zero power consumption, remove power from the workstation.
For additional information on power-saving features, see your operating system documentation.
10 Chapter 1 Product overview ENWW

System fans
The workstation includes a rear chassis fan, one processor heatsink fan, and one power supply fan. An
optional front PCI fan is available for special considerations, such as graphics PCI cards.
Resetting the power supply
If an overload triggers the power supply overload protection, all power is immediately disconnected. To
reset the power supply unit:
1. Disconnect the power cord.
2. Determine what caused the overload and correct the problem.
3. Reconnect the power cord, apply power, and reboot the workstation.
NOTE: When you power down your workstation with the power button on the front panel, the power
consumption falls below 10W. To reach zero power consumption, remove power from the workstation.
For additional information on power-saving features, see your operating system documentation.

The ENERGY STAR Computers Program was created by the EPA to promote energy efficiency and
reduce air pollution through more energy-efficient equipment in homes, offices, and factories. One way
products achieve this is by reducing power consumption when not being used through the Microsoft
Windows ® Power Management feature.
The Power Management feature allows the computer to enter into a low-power or “sleep” mode after a
period of user inactivity. When used with an external ENERGY STAR compliant monitor, this feature
will also support similar power management features of the monitor. To take advantage of this energy
savings:
●The Power Management feature has been preset to power down the computer after 30 minutes of
user inactivity.
●The Power Management feature has been preset to power down the monitor after 15 minutes of
user inactivity.
Both the computer and monitor can be woken from “sleep” mode through user interaction with any of
the computer’s input devices (for example; mouse, keyboard, and others). When configured with Wake
On LAN (WOL) enabled, the computer can also be awoken by a network signal.
More information on the energy and financial savings potential of the Power Management Feature can
be found at the EPA’s ENERGY STAR Power Management website: http://www.energystar.gov/

More information on the ENERGY STAR program and its environmental benefits is available by visiting
the EPA ENERGY STAR Web site: http://www.energystar.gov.
CAUTION: Using the Energy Save Monitor feature with non–ENERGY STAR compliant monitors may
cause video distortion when the Energy Save timeout occurs.
NOTE: ENERGY STAR is not supported on Linux workstations.
If you must restore the operating system, reset the ENERGY STAR settings (if applicable) after the
restore.
Using the ENERGY STAR Save Monitor feature with non-ENERGY STAR-compliant monitors might
cause video distortion when the Energy Save timeout occurs.
NOTE: Not all configurations of the HP xw4550 Workstation are Energy Star compliant. For
information on configurations of this workstation that are Energy Star compliant, contact you HP sales
representative.
To verify the factory default power settings for your product, select Start>Control Panel and double-
