CONFIGURING the SERVER
STEP 7 ORDER OPTIONAL NETWORK CARD ACCESSORIES
Copper twinax cables and SFP optical modules may be ordered to support the two-port network cards that 
are available with the server. 
Choose Optional Twinax Cables
Tab le  10 lists the copper twinax cables available for the PCIe cards. You can choose cable 
lengths of 1, 3, 5, 7, or 10 meters. The two longer cables (7 and 10 meters) are active, which 
means that they contain active components within the SFP+ housing to improve signal quality.
Approved Configurations
(1) Choose Up to Two Twinax Cables for Each Network Card Ordered
■ You may choose one or two twinax cables for each network card ordered. The cables can be 
different lengths; however, you would normally order two cables of equal lengths to connect 
to the primary and redundant network switching equipment.
