Operations
This chapter describes the hardware operations carried out prior to and after installing or removing a
hardware option, or performing a server maintenance or troubleshooting procedure.
Before performing these hardware operations, review and observe the server warnings and cautions.
Power up the server
The SL/XL chassis firmware initiates an automatic power-up sequence when the servers are installed. If
the default setting is changed, use one of the following methods to power up each server:
• Use a virtual power button selection through iLO 5.
• Press and release the Power On/Standby button.
When the server goes from standby mode to full power mode, the server power LED changes from amber
to green.
Power down the server
Before powering down the server for any upgrade or maintenance procedures, perform a backup of
critical server data and programs.
IMPORTANT:
When the server is in standby mode, auxiliary power is still being provided to the
system.
To power down the server, use one of the following methods:
• Press and release the Power On/Standby button.
This method initiates a controlled shutdown of applications and the OS before the server enters
standby mode.
• Press and hold the Power On/Standby button for more than 4 seconds to force the server to enter
standby mode.
This method forces the server to enter standby mode without properly exiting applications and the OS.
If an application stops responding, you can use this method to force a shutdown.
• Use a virtual power button selection through iLO 5.
This method initiates a controlled remote shutdown of applications and the OS before the server
enters standby mode.
Before proceeding, verify that the server is in standby mode by observing that the system power LED is
amber.
Installing drive blanks and thermal bezel blanks for
components with thermal limitations
Depending on the chassis model and the system fan mode, some components might be subject to
thermal limitations. For some cases, it is recommended to remove some installed drives and replace them
with thermal bezel blanks or drive blanks.
