Figure 11: Port Groups for Fabric Port Channels
Caution Adding a second link to a fabric-port-channel port group is disruptive and will automatically increase the
available amount of VIF namespace from 63 to 118. Adding further links is not disruptive and the VIF
namespace stays at 118.
Caution Linking a chassis to two fabric-port-channel port groups does not affect the VIF namespace unless it is manually
acknowledged. The VIF namespace is then automatically set to the smaller size fabric port-channel port group
usage (either 63 or 118 VIFs) of the two groups.
For high availability cluster-mode applications, we strongly recommend symmetric cabling configurations.
If the cabling is asymmetric, the maximum number of VIFs available is the smaller of the two cabling
configurations.
For more information on the maximum number of VIFs for your Cisco UCS environment, see the Configuration
Limits document for your hardware and software configuration.

The fabric interconnect uses a front-end power supply. The chassis has slots for two power supplies. Two
power supplies can be used for redundancy, but the fabric interconnect is fully functional with one power
supply. Power supplies have two LEDs: one for power status and one for failure condition.
