Compute module preparation
To service any internal compute module component:
Procedure
1. Power down the compute module.
2. Remove the compute module
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. Also, before
proceeding, verify that both the:
•
Compute module is in standby mode by observing that the system power LED is amber.
•
UID LED is not flashing blue.
IMPORTANT:
•
When the compute module is in standby mode, auxiliary power is still being provided to the system.
•
Always attempt a graceful shutdown before forcing the shutdown of applications and the OS with a
nongraceful shutdown.
•
Before proceeding, note that 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, either:
◦
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, force a nongraceful shutdown of applications and the OS by either:
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.
