The following minimum hardware, browser, and port requirements must be met prior to Cisco UCS Manager initial configuration.

Before you set up Cisco UCS Manager, make sure that the following physical cabling requirements are met:

Note	The Cisco UCS Fabric Interconnects act as the concentration point for all cabling to and from the Blade Server Chassis. The following diagram shows the Cisco UCS Fabric Interconnects Cluster Connectivity.

• Connect the two fabric interconnects using the integrated ports labeled L1 and L2. These ports are used for replication of cluster information between the two fabric interconnects, not for the forwarding of data traffic.

• The management Ethernet ports of each fabric interconnect to the out-of-band Ethernet management network or Ethernet segment where they can be accessed for overall administration of the system.

• Populate each blade chassis with two fabric extenders (I/O modules) to provide connectivity back to the fabric interconnects.

• From the Blade Server Chassis, connect one I/O module to the first fabric interconnect. Connect the second I/O module to the second fabric interconnect. After you have configured the fabric interconnects, they will be designated as "A" and "B" fabric interconnects.

Note	You can connect the I/O modules to the fabric interconnects by using one, two, four, or eight cables per module. For system resiliency and throughput, it is recommended that you use a minimum of two connections per I/O module
