SUPPLEMENTAL MATERIAL
VIC 1340/1240 and Port Expander
Adapter slot 1 is dedicated to the VIC 1340 or VIC 1240 adapter, and no other adapter card can be installed
in this slot. There are two groups of four ports on the VIC 1340/1240:
■ Two ports of the first group and two ports of the second group are wired through the UCS
5108 Blade Server chassis to Fabric Extender A and Fabric Extender B.
■ The other two ports of each group are wired to adapter slot 2. The VIC 1340 or 1240 adapter
senses the type of adapter installed in adapter slot 2. If a Port Expander is installed in
adapter slot 2, the four 10G KR ports between the adapters are used for port expansion;
otherwise they are unused.
With the Port Expander installed, there are up to eight 10 Gb network interfaces to each Fabric Extender
(depending on the Fabric Extender installed), as represented in
Figure 12.
