Cisco Cisco UCS B200 M2 Blade Server Datenbogen

C-Series servers connect to external FEXs and FIs as summarized in this section. Two interconnection 
methods are possible:

■

Single-Wire Management

■

Dual-Wire Management

Cisco UCS Manager 3.1 supports an additional option to integrate the C-Series Rack-Mount Server with Cisco 
UCS Manager using the NC-SI. This option enables Cisco UCS Manager to manage the C-Series Rack-Mount 
Servers using a single-wire for both management traffic and data traffic. When you use the single-wire 
management mode, one host facing port on the FEX is sufficient to manage one rack-mount server, instead 
of the two ports you would use in the Shared-LOM mode. This connection method allows you to connect 
more rack-mount servers with Cisco UCS Manager 3.1 for integrated server management. Make sure you 
have correct server firmware for integration with Cisco UCS Manager. If not, upgrade your server firmware 
before integrating the server with Cisco UCS Manager.

 shows how the C-Series rack mount chassis connect to the FEXs and FIs for single-wire 

management.
