Overview
The Cisco UCS 6536 Fabric Interconnect (UCSC-FI-6536) is a 1-rack unit (RU), top of rack (TOR), fixed-port
data center platform that provides both network connectivity and management capabilities to the Cisco UCS
system.
The fabric interconnect can provide Ethernet and Fibre Channel connectivity to the servers in the system. The
servers connect to the fabric interconnect, and then to the LAN or SAN.
High availability redundancy can be achieved when a fabric interconnect is connected to another fabric
interconnect through the L1 or L2 port on each device.
Each Cisco UCS 6536 Fabric Interconnect offers the following features:
• Thirty-six QSFP28 ports capable of 100G including 4 unified ports (33-36). Ports also support:

• Autonegotiating with peer devices to speeds of 40G, 25G, 10G, and 1G.
• Port breakout is supported for Ethernet ports (1-32) and Unified ports (33-36).
• Ethernet breakout is supported on chassis ports 1 through 36 when each port is configured with
a breakout cable.
• The Dynamic Ethernet Breakout feature enables converting a standard Ethernet port to a
breakout port on-the-fly so that you do not need to reboot the Fabric Interconnect. Dynamic
Ethernet Breakout also supports converting breakout ports back to a standard Ethernet
port without a reboot.
• FC breakout is supported on chassis ports 33 through 36 when each port is configured with a
four-port breakout cable, for example 1/33/1, 1/33/2, 1/33/3, and 1/33/4 for four FC breakout
ports on chassis physical port 33.
Note
Fibre Channel support is only available via configuring Unified Ports (33-36) as
FC breakout.
