These symbols, on power supplies or systems,
indicate that the equipment is supplied by multiple
sources of power.
WARNING:
To reduce the risk of injury from electric shock,
remove all power cords to disconnect power
from the system completely.
Compute module preparation
To service any internal compute module component:
Procedure
1. Power down the compute module .
2. Remove the compute module from the frame.
Powering down the compute module
Before powering down the compute module for any upgrade or maintenance procedures, perform a backup of
critical data and programs.
IMPORTANT:
When the compute module is in standby mode, auxiliary power is still being provided to the system.
IMPORTANT:
Always attempt a graceful shutdown before forcing the shutdown of applications and the OS with a non-
graceful shutdown.
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, use one of the following methods:
◦ 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.
Always attempt a graceful shutdown first before forcing the compute module to power off.
• If a graceful shutdown fails to power down the compute module to standby mode when an application or
OS stops responding, use one of the following methods to force a non-graceful shutdown of applications
and the OS:
◦ 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.
Application data can be lost when performing a non-graceful shutdown of applications and the OS.
Before proceeding, verify that the compute module is in standby mode by observing that the system power
LED is amber.
