Removal and replacement procedures
Required tools
You need the following items for some procedures:
• T-10/T-15 Torx screwdriver
• HPE Insight Diagnostics software ("HPE Insight Diagnostics" on page 69)
Preparation procedures
To access some components and perform certain service procedures, you must perform one or more of
the following procedures:
• Extend the server from the rack (on page 26).
If you are performing service procedures in a Hewlett Packard Enterprise, Compaq branded, Telco,
or third-party rack cabinet, you can use the locking feature of the rack rails to support the server and
gain access to internal components.
For more information about Telco rack solutions, refer to the RackSolutions.com website
(http://www.racksolutions.com/hpe).
• Power down the server (on page 25).
If you must remove a server from a rack or a non-hot-plug component from a server, power down the
server.
• Remove the server from the rack.
If the rack environment, cabling configuration, or the server location in the rack creates awkward
conditions, remove the server from the rack.
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 HPE iLO.
This method initiates a controlled remote shutdown of applications and the OS before the server
enters standby mode.
