Expansion card installation guidelines
Before installing any supported expansion card into a PCI or PCI Express card slot, ensure that you observe
the following guidelines:
• Only one Host Bus Adapter can be installed.
• Up to three Ethernet cards can be installed.
• If the ThinkServer RAID 300 is available, your server does not support Host Bus Adapters or discrete
graphics cards.
• If a RAID 500 Adapter, a RAID 700 Adapter, or a RAID 710 Adapter is installed, or the ThinkServer RAID
100 is available, your server supports one Host Bus Adapter or one discrete graphics card. However, if an
I350-T4 Ethernet card is installed, your server does not support Host Bus Adapters or graphics cards.
Notes:
• If a ThinkServer Host Bus Adapter is available, refer to its user guide and the table below for detailed
information. The user guide is available for download at:

• If the server does not have a RAID card or a VGA adapter card installed, the Host Bus Adapter also
can be installed in the PCI Express x16 card slot (PCI-E slot 5) on the system board. See “System
board components” on page 48.
• If you are installing the QLE8242 Converged Network Adapter, do not install it in the PCI-E slot 4 to avoid
thermal problems. See “System board components” on page 48.
