This section provides specific information about the system jumpers. It also provides some basic information on jumpers and switches and describes the connectors on the various boards in the system.
System Board Jumpers
Figure 6-1 shows the location of the configuration jumpers on the system board. Table 6-1 lists the jumper settings.
NOTE: To access the jumpers, remove the system board cooling shroud by lifting the release latch and sliding the shroud towards the front of the system. See Figure 3-13.
NOTE: Lift up the memory module airflow shroud for easy access to the jumpers.

PWRD_EN
(default)
The password feature is enabled.
The password feature is disabled.
2
NVRAM_CLR
(default)
The configuration settings are retained at system boot.
The configuration settings are cleared at the next system boot. (If the configuration settings become corrupted to the point where the system will not boot, install the jumper and boot the system. Remove the jumper before restoring the configuration information.)
NOTE: For the full name of an abbreviation or acronym used in this table, see the Glossary.
Disabling a Forgotten Password
The system's software security features include a system password and a setup password, which are discussed in detail in Using the System Setup Program. The password jumper enables these password features or disables them and clears any password(s) currently in use.
NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions in your Product Information Guide.
Turn off the system, including any attached peripherals, and disconnect the system from the electrical
outlet.
See Figure 6-1 to locate the password jumper on the system board.
Close the system.
Reconnect your system and peripherals to their electrical outlets, and turn on the system.
The existing passwords are not disabled (erased) until the system boots with the password jumper plug removed. However, before you assign a new system and/or setup password, you must install the jumper plug.
NOTE: If you assign a new system and/or setup password with the jumper plug still removed, the system disables the new password(s) the next time it boots.
Turn off the system, including any attached peripherals, and disconnect the system from the electrical
outlet.

Expansion-Card Riser-Board Components and PCI Buses
There are two expansion card configurations for this systems. Each riser (center riser and left riser) contains one slot for either a PCI-X configuration or a PCIe configuration. This system supports only one configuration (PCI-X or PCIe) for both risers. Figure 6-6 and Figure 6-7 show the components on the optional PCI-X expansion-card riser boards, including the expansion-card slots and buses. PCIe Riser Board Expansion Slots and PCI-X Riser Board Expansion Slots list the PCI bus and operating speed for each expansion-card slot.
NOTE: Because the orientation and physical connectors are similar, the PCIe expansion card configuration is not shown.
