Cisco UCS 6454 Fabric Interconnect Overview
The Cisco UCS 6454 Fabric Interconnect provides both network connectivity and management capabilities
to the Cisco UCS system. The fabric interconnect provides Ethernet and Fibre Channel to the servers in the
system, the servers connect to the fabric interconnect, and then to the LAN or SAN.
Each Cisco UCS 6454 Fabric Interconnect runs Cisco UCS Manager to fully manage all Cisco UCS elements.
The fabric interconnect supports 10/25 Gigabit ports in the fabric with 40/100 Gigabit uplink ports. High
availability can be achieved when a Cisco UCS 6454 Fabric Interconnect is connected to another Cisco UCS
6454 Fabric Interconnect through the L1 or L2 port on each device.
Cisco UCS 6454 Fabric Interconnect
The Cisco UCS 6454 Fabric Interconnect is a 1 RU top-of-rack switch with 48 10/25-Gigabit SFP28 ports (8
unified ports) and six 40/100-Gigabit QSFP28 ports. The eight unified ports support 10/25 GbE or 8/16/32G
Fibre Channel speeds. The switch also has one network management port, a console port for setting the initial
configuration, and a USB port for saving or loading configurations. The switch also includes L1/L2 ports for
connecting two fabric interconnects to provide high availability. The switch mounts in a standard 19-inch
rack, such as the Cisco R Series rack. The Cisco UCS 6454 Fabric Interconnect also contains a CPU board
which consists of:
Ports 9-44 (10/25 Gbps Ethernet or FCoE)2Ports 1-8 (Unified Ports 10/25 Gbps
Ethernet or FCoE or 8/16/32 Gbps Fibre
Channel)

Uplink Ports 49-54 (40/100 Gbps Ethernet
or FCoE)
For additional information about the port groups, see Port Numbering, on page 4.
The Cisco UCS 6454 Fabric Interconnect chassis has two power supplies and four fans. Two of the fans
provide front to rear airflow.

Ports on the Cisco UCS 6454 Fabric Interconnect
The ports on the Cisco UCS 6454 Fabric Interconnect can be configured to carry either Ethernet or Fibre
Channel traffic. You can configure only the first eight ports to carry Fibre Channel traffic. The ports cannot
be used by a Cisco UCS domain until you configure them.
When you configure a port on a fabric interconnect, the administrative state is automatically set to enabled.
If the port is connected to another device, this may cause traffic disruption. The port can be disabled and
enabled after it has been configured.
The following table summarizes the second, third and fourth generation ports for the Cisco UCS fabric
interconnects.

Uplink Ports 49–54. Each port can operate
as either a 40 Gbps or 100 Gbps Ethernet

to connect to network or FCoE uplink ports
and not UCS server ports. These ports do
not support breakout cables or QSA
module.
The fabric interconnect has two power supplies that are accessible from the front of the chassis. The two
power supplies support 1+1 redundancy. The Cisco UCS 6454 Fabric Interconnect and the UCS 6300 Series
Fabric Interconnect utilize the same power supplies.

Fan Modules
The Cisco UCS 6454 Fabric Interconnect supports four fan modules. The fans support 3+1 redundancy. The
Cisco UCS 6454 Fabric Interconnect and the UCS 6300 Series Fabric Interconnect utilize the same model
fans. All fans are hot swappable but only one fan can be removed at a time.

Supported Transceivers
The Cisco UCS 6454 Fabric Interconnect support SFP28 Ethernet transceivers, SFP transceivers, SFP28
transceivers, SFP28 copper twinax cables with integrated transceivers, SFP Fibre Channel transceivers, QSFP
transceivers, QSFP28 transceivers, and QSFP cables. Except where noted, both the Cisco UCS 6454 Fabric
Interconnect support all the transceivers listed in this section. Ports 1–8 operate as unified ports that are capable
of 10/25-Gbps fixed Ethernet, 10/25-Gbps FCoE, or 8-, 16-, or 32 Gbps Fibre Channel ports.
The SFP 1-Gigabit Ethernet transceiver module is a bidirectional device with a transmitter and receiver in the
same physical package.
Table 2: Supported SFP Optical Transceivers
Note
The maximum length of fiber optic runs is limited to 300 meters. This is imposed by our use of
802.3X/802.1Qbb Priority Pauses. SFP-10G-LR is supported between fabric interconnect and I/O Module,
but the 300 meter limit still applies. For copper wiring the maximum distance is 100 meters.

The enhanced SFP+ 10-Gigabit Ethernet transceiver module is a bidirectional device with a transmitter and
receiver in the same physical package. It has a 20-pin connector on the electrical interface and duplex LC
connector on the optical interface.
The maximum length of fiber optic runs from the fabric interconnect to a chassis is limited to 300 meters.
This restriction is imposed by the use of 802.3X/802.1Qbb Priority Pauses.
Before you install, operate, or service the system, read the Regulatory Compliance and Safety Information
