5. Move the jumper from the standard position (pin 1 and pin 2) to the maintenance position (pin 2 and
pin 3).
6. Reconnect any cables that were disconnected and reinstall the PCI card if removed.
7. Reinstall the computer cover and reconnect the power cords for the computer and monitor to electrical
outlets. See “Completing the parts replacement” on page 104.
8. Turn on the computer and then insert the POST and BIOS update (ash update) disc into the optical
drive. Wait a few minutes. Then, the recovery session begins. The recovery session will take two to
three minutes. During this time, a warning message will be displayed and no action is needed from you.
9. After the recovery session is completed, there will be no video, and your computer will automatically
turn off.
10. Repeat step 1 through step 4.
11. Move the Clear CMOS /Recovery jumper back to the standard position (pin 1 and pin 2).
12. Reconnect any cables that were disconnected and reinstall the PCI card if removed.
13. Reinstall the computer cover and reconnect any cables that were disconnected.
14. Turn on the computer to restart the operating system.
Power management
Power management reduces the power consumption of certain components of the computer such as the
system power supply, processor, hard disk drives, and some monitors.
Automatic conguration and power interface (ACPI) BIOS
Being an ACPI BIOS system, the operating system is allowed to control the power management features
of the computer and the setting for Advanced Power Management (APM) BIOS mode is ignored. Not
all operating systems support ACPI BIOS mode.
Automatic Power-On features
The Automatic Power-On features within the Power Management menu allow you to enable and disable
features that turn on the computer automatically.
• Serial Port A Ring Detect: With this feature set to Enabled and an external modem connected to serial
port (COM1), the computer will turn on automatically when a ring is detected on the modem.
• PCI Modem Ring Detect: With this feature set to Enabled, the computer will turn on automatically
when a ring is detected on the internal modem.
• PCI Wake Up: This feature allows PCI cards that support this capability to wake the system.
• Wake Up on Alarm: You can specify a date and time at which the computer will be turned on
automatically. This can be either a single event or a daily event.
• Wake on LAN: If the computer has a properly congured token-ring or Ethernet LAN adapter card that is
Wake on LAN-enabled and there is remote network management software, you can use the Wake on LAN
feature. When you set Wake on LAN to Enabled, the computer will turn on when it receives a specic
signal from another computer on the local area network (LAN).
System memory speed
The Intel Xeon microprocessor families compatible with this ThinkStation computer feature an integrated
memory controller, which provides the microprocessor with direct access to the system memory. Because
of this design, the system memory speed will be determined by a number of factors, including the
microprocessor model and the type, speed, size (capacity), and number of DIMMs installed. Refer to the
following table for the information on the supported system memory speed for your own computer model.
