Expansion card installation guidelines
Before installing any supported expansion card into a PCI Express card slot, ensure that you observe
the following guidelines:
• Only one Host Bus Adapter can be installed.
• If the ThinkServer RAID 300 is available, your server does not support Host Bus Adapters.
• If a RAID 500 Adapter, a RAID 700 Adapter, or a RAID 710 Adapter is installed, your server supports up
to three Ethernet cards and one Host Bus Adapter. However, if an I350-T4 Ethernet card is installed,
your server does not support Host Bus Adapters.
