Removal and replacement procedures
This chapter provides detailed instructions on how to remove and replace component spare parts.
Required tools
You need T-15 and T-30 Torx screwdrivers for performing procedures listed in this document.
Preparation procedures
To access some components and perform certain service procedures, you must perform one or more of
the following procedures:
• Power down the server on page 21.
If you must remove the chassis from a rack or a non-hot-plug component from the chassis or server,
then you must power down the servers.
• Remove the server from the chassis on page 22.
If the rack environment, cabling configuration, or the chassis location in the rack creates unstable
conditions, then remove the server from the chassis.
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.
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.
