If all other LEDs are off, then no power is present to the compute module. (For example, facility power is not present,
power cord is not attached, no power supplies are installed, power supply failure has occurred, or the compute module is
not properly seated.) If the health LED is flashing green while the system power LED is off, the Power On/Standby button
service is initializing or that an iLO reboot is in progress.

NVMe SSD LED definitions
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 LED is flashing.
The Do not remove LED flashes to indicate that the device is still in use. Removing the NVMe SSD
before the device has completed and ceased signal/traffic flow can cause loss of data.

When the system maintenance switch position 6 is set to the On position, the system is prepared 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 is enabled, some
configurations cannot be restored. For more information, see Secure Boot configuration.
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 compute
module is in Legacy BIOS Boot Mode.

DIMM slot locations
DIMM slots are numbered sequentially (1 through 12) for each processor. The supported AMP modes use the
alpha assignments for population order, and the slot numbers designate the DIMM slot ID for spare
replacement.
The colored slots indicate the slot order within each channel:
•White — First slot of a channel
•Black — Second slot of a channel
•Blue — Third slot of a channel
The arrow points to the front of the compute module.

Operations
Powering up the compute module
To power up the compute module, press the Power On/Standby button after the power button LED has turned
amber.
Powering down the compute module
Before powering down the compute module for any upgrade or maintenance procedures, perform a backup of
the system and all data. Then, shut down, as appropriate, applications and operating systems. A successful
shutdown is indicated by the system power LED displaying amber.
IMPORTANT: Always attempt a graceful shutdown before forcing a nongraceful shutdown. Application
data can be lost when performing a nongraceful shutdown of applications and the OS.
Before proceeding, verify the following:
•The compute module is in standby mode by observing that the system power LED is amber.
•The UID LED is not flashing blue.
NOTE:
◦When the compute module is in standby mode, auxiliary power is still being provided to the system.
◦If the UID LED is flashing blue, a remote session is in progress.
To power down the compute module, use one of the following methods:
•To perform a graceful shutdown of applications and the OS when powering down the compute module to
standby mode, do one of the following:
◦Press and release the Power On/Standby button.
◦Select the Momentary press power off selection in HPE OneView.
◦Select the Momentary press virtual power button selection in HPE iLO.
•If a graceful shutdown fails to power down the compute module to standby mode when an application or
OS stops responding, force a nongraceful shutdown of applications and the OS. Do one of the following:
◦Press and hold the Power On/Standby button for more than four seconds.
◦Select the Press and hold power off selection in HPE OneView.
◦Select the Press and hold virtual power button selection in HPE iLO.
Removing the compute module
Operations17
Procedure
1. Identify the proper compute module.
2. Power down the compute module.
3. Remove the compute module.
4. Place the compute module on a flat, level work surface.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the internal
system components to cool before touching them.
CAUTION: To prevent damage to electrical components, properly ground the compute module
before beginning any installation procedure. Improper grounding can cause ESD.
Removing and replacing an access panel
Procedure
1. Power down the compute module.
2. Remove the compute module.
3. Press the access panel release button.
4. Slide the access panel towards the rear of the compute module, and then lift to remove the panel.
