Product Overview
This describes the Cisco UCS Fabric Interconnects and their components, and includes the following sections:
Interconnect Features
A Cisco UCS 6100 series fabric interconnect is a top-of-rack fabric interconnect that provides Ethernet and Fibre Channel to all servers in the rack. Servers connect to the fabric interconnect, and it connects to the LAN or SAN.
This family of fabric interconnects connect UCS servers to 10 Gigabit Ethernet 1, 2, and 4 Gbps Fibre Channel networks, and provides consolidated I/O connectivity to both production Ethernet LANs and Fibre Channel SANs in a cost-effective, high-performance, low-latency environment.
The Cisco UCS 6100 series has the following characteristics:
•
Depending on the model and expansion modules used, 20 to56 ports are on the back of the chassis. The Cisco UCS 6120XP has 20 ports on the base system and can be upgraded with one expansion module. The Cisco UCS 6140XP has 40 ports on the base system and can be upgraded with two expansion modules.

•
The Ethernet connector port exposes four Ethernet ports that are in a 2x2 stacked RJ-45 jack. Figure 1-1 shows a close-up view of the Ethernet connector port.

Expansion Modules
Expansion modules allow Cisco UCS 6100 Series Fabric Interconnect to be configured as cost-effective 10-Gigabit Ethernet fabric interconnects and as I/O consolidation platforms with native Fibre Channel connectivity. The Cisco UCS 6120XP has one slot for an optional uplink expansion module. The Cisco UCS 6140XP has two slot for an optional uplink expansion module.There are several modules that can be accommodated in this slot:
•
•
•
•
The chassis supports hot swapping of the expansion modules. If the expansion modules are not in place, a cover plate should be used to ensure proper airflow in the chassis.

Ports
Each individual port is numbered, and groups of ports are numbered based on their function. The ports are numbered top to bottom and left to right.
Cisco UCS 6120XP
There are 20 to 28 ports on the Cisco UCS 6120XP, depending on which expansion module is installed. The fixed ports form group 1 and are named 1/port_number. Ports 1 through 20 are unencrypted Ethernet ports. Of these, ports 1 through 8 are 10-Gigabit Ethernet and 1-Gigabit Ethernet-capable ports. Group 2 includes the ports in the expansion module or modules. Group 2 ports 1 through 4 are Ethernet ports. Group 2 ports 5 through 8 are Fibre Channel ports.

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. Figure 1-21 shows the 550 W power supply, which has two LEDs: one for power status and one for failure condition. Figure 1-22 shows the 750 W power supply, which has two LEDs: one for power status and one for failure condition.

Table 1-3 describes the status of the two power supply LEDs.
If one power supply is installed in the chassis, but the other power supply slot is empty, a blank filler panel should be used to cover the empty slot. Figure 1-23 shows a blank power supply filler panel.

Fan Module
TheCisco UCS 6120XP fabric interconnect has slots for two fan modules. Each fan module houses 6 fans. The combination of 6 fans per module and 2 modules provides the chassis with 12 fans. Figure 1-24 shows the fan module for the Cisco UCS 6120XP.
Figure 1-24 Cisco UCS 6120XP Fan Module (N10-FAN1=)
The Cisco UCS 6140XP fabric interconnect has five fan modules. Figure 1-25 shows the fan module.
