• 24-drive configuration—Install the expander card into slot 5 of the primary riser cage. A SAS controller
must be installed in slot 6.
• 48-drive configuration—Install the expander cards into slot 5 of the primary riser cage, and into slot 15 of
the butterfly riser cage. SAS controllers must be installed in slots 6 and 16.
To ensure that cables are connected correctly, observe the labels on the cable and component connectors.
Be sure that you have the latest firmware for the controllers and the expander card. To download the latest
firmware, see the Hewlett Packard Enterprise website (http://www.hpe.com/support/hpesc).
WARNING:
To reduce the risk of personal injury, electric shock, or damage to the equipment, remove power from
the server by removing the power cord. The front panel Power On/Standby button does not shut off
system power. Portions of the power supply and some internal circuitry remain active until AC power is
removed.
CAUTION:
To prevent improper cooling and thermal damage, do not operate the server unless all PCI slots have
either an expansion slot cover or an expansion board installed.
Prerequisites
• The components included with the hardware option kit
• Cables for each drive box
• A SAS controller for each expander
Procedure
1. Power down the server on page 32.
2. Remove all power:
a. Disconnect each power cord from the power source.
b. Disconnect each power cord from the server.
3. Do one of the following:
• Extend the server from the rack (Extending the server from the rack on page 32).
• Remove the server from the rack (Removing the server from the rack on page 33).
4. Remove the access panel (Removing the access panel on page 36).
CAUTION:
Do not operate the server for long periods with the access panel open or removed. Operating the
server in this manner results in improper airflow and improper cooling that can lead to thermal
damage.
5. Remove the riser cage (Removing a PCIe riser cage on page 39).
6. Remove the expansion slot blank from slot 5 (primary riser cage) or slot 15 (butterfly riser cage).
