Installing an adapter
The dx340 configurations support installation of one or two adapters. The following
sections describe installing adapters for each type of configuration.
The following notes describe the types of adapters that the server supports and
other information that you must consider when you install an adapter:
v Locate the documentation that comes with the adapter and follow those
instructions in addition to the instructions in this section. If you have to change
switch settings or jumper settings on the adapter, follow the instructions that
come with the adapter.
v
Read the documentation that comes with your operating system.
v The server comes with a one-slot or two-slot PCI Express (PCIe) riser card. The
riser card connectors support the following types of adapters:
– One-slot riser card: PCIe x16 (x8) adapters
– Two-slot riser card: PCIe x16 (x8) adapters.
Important: The (x8) designation identifies an x16 connector that supports x8
adapters and x16 adapters that can downshift to operate at the x8 bandwidth.
For example, if you install an x16 adapter that can downshift to the x8
bandwidth in the connector, the adapter will run at the x8 bandwidth. See the
documentation that comes with the adapter for compatibility information.
v In configurations that have a two-slot riser card, the server scans the PCI
Express adapters to assign system resources, following the boot sequence that
is set in the BIOS configuration utility program.
Important: The maximum power consumption from all supply voltages for a
single PCIe slot is the same as specified in PCI Local Bus Specification Revision
2.3 for conventional slots (25 W).
