CONFIGURING the SERVER
Approved Configurations
(1) Choose Up to Two SFP+ Modules for Each Network Card Ordered
■ You may choose one or two SFP+ optical modules cables for each compatible PCIe network
card ordered. You would normally order two modules for connecting to the primary and
redundant network switching equipment. With the SFP+ optical modules, you can use
common fiber optic cables, widely available.
See the Figure 5 on page 32 for typical SFP+ and twinax connections to the network cards.
Caveats
Check the table on the following page for compatibility between the PCIe network cards and
SFPs or twinax cables.
NOTE: The table shows all PCIe network cards for all C-series servers. Not all of the
cards shown in the table are supported in this server. The intent of the table is to
show compatibility between cards and twinax cables or SFPs.
