Chapter 3. IBM System x3850 X5 and x3950 X5 105
Figure 3-26 Top view of slot 6 and 7 showing that slot 7 is slightly longer than slot 6
The Emulex 10Gb Ethernet Adapter in the x3850 X5 has been customized with a special type
of connector called an
extended edge connector. The card itself is colored blue instead of
green to indicate that it is nonstandard and cannot be installed in a standard x8 PCIe slot.
At the time of writing, only the x3850 X5 and the x3690 X5 have slots that are compatible with
the custom-built Emulex 10Gb Ethernet Adapter that is shown in Figure 3-27.
Figure 3-27 The Emulex 10Gb Ethernet Adapter has a blue circuit board and a longer connector
The Emulex 10Gb Ethernet Adapter is a customer-replaceable unit (CRU). To replace the
adapter (for example, under warranty), order the CRU number, as shown in Table 3-32 on
page 106. The table also shows the regular Emulex 10Gb Virtual Fabric Adapter (VFA) for
IBM System x option, which differs only in the connector type (standard x8) and color of the
circuit board (green).
Tip: The Emulex 10Gb Ethernet Adapter that is standard with most models is a custom
version of the Emulex 10Gb Virtual Fabric Adapter for IBM System x, part number
49Y4250. However, the features and functions of the two adapters are identical.
At 106
pins, slot 7
is slightly
longer than
a standard
x8 PCIe
slot
