*You can access the redundant ROM bysetting S1, S5, and S6 to On.
**When the system maintenance switch position 6 is setto the On position, the system isprepared to restore all
configuration settings to their manufacturing defaults.
When the system maintenance switch position 6 is set to the On position and Secure Boot isenabled, some
configurations cannot be restored. For more information, see Secure Boot configuration (on page 127).
IMPORTANT:
Before using the S7 switch to change to Legacy BIOS Boot Mode, be sure the
HPE Dynamic Smart Array B140i Controller is disabled. Do not use the B140i controller when
the server is in Legacy BIOS Boot Mode.
NMI jumper
The NMI jumper allows administrators to perform a memory dump before performing a hard reset. Crash
dump analysis is an essential part of eliminating reliability problems, such as hangs or crashes in OSs,
device drivers, and applications. Many crashes can freeze a system, requiring you to do a hard reset.
Resetting the system erases any information that would support root cause analysis.
Systems running Microsoft® Windows® experience a blue-screen trap when the OS crashes. When this
happens, Microsoft® recommends that system administrators perform an NMI event by temporarily
shorting the NMI header with a jumper. The NMI event enables a hung system to become responsive
again.

Component identification 16
DIMM slots
DIMM slots are numbered sequentially (1 through 12) for each processor. Thesupported AMP modes use
the letter assignments for population guidelines.
NVDIMM LEDs
When the server boots up, all LEDs flash three times. Any LED activity not described in this section
indicates a possible error.

Notes:
•"Primary" denotes the riser cage is installed in the primary riser connector.
•"Secondary" denotes the riser cage is installed in the secondary riser connector.
•Installing the riser cages listed in the table above in either the primary or secondary riser connectors

NVMe SSD components
The NVMe SSD is a PCIe bus device. A device attached to a PCIe bus cannot be removed without
allowing the device and bus to complete and cease the signal/traffic flow.
CAUTION: Do not remove an NVMe SSD from the drive bay while the Do Not Remove
button LED is flashing. The
Do Not Remove button LED flashes to indicate the device is still in
use. Removal of the NVMe SSD before the device has completed and ceased signal/traffic
flow can cause loss of data.

CAUTION:
To avoid damage to server components, fan blanks must be installed in fan bays
1 and 2 in a single-processor configuration.

For a single-processor configuration, five fans and two blanks are required in specific fan bays for
redundancy.
For a dual-processor configuration, seven fans are required for redundancy. A fan failure or missing fan
causes a loss of redundancy. A second fan failure or missing fan causes an orderly shutdown of the
server.
The high performance fan option might be necessary for the following installations:
•LR DIMM configuration
•ASHRAE compliant configurations
For more information, see the Hewlett Packard Enterprise website
(http://www.hpe.com/servers/ASHRAE).
The server supports variable fan speeds. The fans operate at minimum speed until a temperature change
requires a fan speed increase to cool the server. The server shuts down during the following
temperature-related scenarios:
•At POST and in the OS, iLO 4 performs an orderly shutdown if a cautionary temperature level is
detected. If the server hardware detects a critical temperature level before an orderly shutdown
occurs, the server performs an immediate shutdown.
•When the Thermal Shutdown feature is disabled in RBSU, iLO 4 does not perform an orderly
shutdown when a cautionary temperature level is detected. Disabling this feature does not disable
the server hardware from performing an immediate shutdown when a critical temperature level is
detected.
CAUTION: A thermal event can damage server components when the Thermal Shutdown
feature is disabled in RBSU.
