RJ ‐ 45 Cable Specifications
Table 1 below lists the recommended cable specifications for various Ethernet port
types. Depending on the intended use, attach a suitable cable. For example, to
achieve 10 Gb/s performance, use a Category 6 cable. To achieve the desired
performance, the adapter must be connected to a compliant link partner, such as an
IEEE 802.3an ‐ compliant gigabit switch.
2.5 Attaching a Cable (SFP+)
Solarflare SFP+ Server Adapters can be connected to the network using either an
SFP+ Direct Attach cable or a fiber optic cable.
Attaching an SFP+ Direct Attach Cable
To attach an SFP+ Direct Attach cable:
1 Turn the cable so that the connector retention tab and gold fingers are on the
same side as the network adapter retention clip.
2 Push the cable connector straight in to the adapter socket until it clicks into
place.
