Product Overview

Fabric Interconnect Features

A Cisco UCS 6300 Series Fabric Interconnect provides both network connectivity and management capabilities to a 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 the fabric interconnect connects to the LAN or SAN.

Each Cisco UCS 6300 Series Fabric Interconnect runs Cisco UCS Manager to fully manage all Cisco UCS elements. The fabric interconnect supports full end-to-end 40-Gigabit capabilities in the fabric and enables 16-Gigabit Fibre Channel capabilities. High availability can be achieved when a Cisco UCS 6300 Series Fabric Interconnect is connected to another Cisco UCS 6300 Series Fabric Interconnect through the L1 or L2 port on each device.

The Cisco UCS 6300 Series Fabric Interconnect joins next-generation UCS products, including the following hardware:

  • Cisco UCS 6332 Fabric Interconnect, an Ethernet or Fibre Channel over Ethernet (FCoE) chassis with 32 40-Gigabit QSFP+ ports

  • Cisco UCS 6332-16UP Fabric Interconnect, an Ethernet, FCoE, and Fibre Channel chassis with 16 1- or 10-Gigabit SFP+ ports or 16 4-, 8-, or 16-Gigabit Fibre Channel ports, 24 40-Gigabit QSFP+ ports

  • Cisco 2304 IOM , I/O module with 8 40-Gigabit backplane ports and 4 40-Gigabit uplink ports

  • Multiple VICs

Cisco UCS 6332 Fabric Interconnect

The Cisco UCS 6332 Fabric Interconnect is a 1 RU, top-of-rack switch with 32 40-Gigabit QSFP+ ports, one 100/1000 network management port, one RS-232 console port for setting the initial configuration, and two USB ports for saving or loading configurations. The switch also includes an L1 port and an L2 port 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.

Cooling fans pull air front-to-rear. That is, air intake is on the fan side and air exhaust is on the port side.

Ports on the Cisco UCS 6300 Fabric Interconnects

Ports on the Cisco UCS 6300 Series can be configured to carry either Ethernet or Fibre Channel traffic. These ports are not reserved. They cannot be used by a Cisco UCS domain until you configure them.


Note

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. You can disable the port after it has been configured.

The following table summarizes the second and third generation ports for the Cisco UCS fabric interconnects.

Port Breakout Feature

Both the Cisco UCS 6332 fabric interconnect and the Cisco UCS 6332-16UP fabric interconnect have ports that can be configured for the breakout feature that supports connectivity between 40-Gigabit Ethernet ports and 10-Gigabit Ethernet ports. This feature provides backward compatibility to existing hardware that supports 10-Gigabit Ethernet. A 40-Gigabit Ethernet port can be used as 4 10-Gigabit Ethernet ports. Using a 40-Gigabit Ethernet SFP, these ports on the UCS 6300 Series fabric interconnect can be configured as an appliance port, server port (IOM, Fabric Extender, or C-series server), uplink, FCoE uplink and/or FCoE storage port.

The breakout feature can be configured on ports 1 to 12 and ports 15 to 26 on the Cisco UCS 6332 fabric interconnect. Ports 17 to 34 on the Cisco UCS 6332-16UP fabric interconnect support the breakout feature. For information on how to configure the breakout feature, see the Getting Started Guide for the latest release of Cisco UCS Manager. The configuration guides are available at this URL: http://www.cisco.com/c/en/us/support/servers-unified-computing/ucs-manager/products-installation-and-configuration-guides-list.html.


Note
Configuring the breakout feature requires a reboot of the fabric interconnect.

Power Supplies

The fabric interconnect has two power supplies that are accessible from the rear of the chassis. Two power supplies can be used for redundancy, but the fabric interconnect is fully functional with one power supply.

QSFP+ port LEDs on the front of the chassis allow you to see the link status of the ports. When you press the push button on the front panel, a QSFP+ port LED shows the link and activity status for the selected lane, and one of the four green LEDs show which lane is selected. You can press the push button four times to check all four lanes of each QSFP+ port. After the fourth press, all LEDs turn off, indicating that the current link status is 40-Gbps mode, which is the default mode.

Lane Switch and LEDs

Both the Cisco UCS 6332 Fabric Interconnect and the UCS 6332-16UP Fabric Interconnect have a lane switch button and lane LEDs that are shown in the following figure:

QSFP+ lane LEDs

The port lane switch operates as follows:

  • The default mode of operation after bootup is 40-Gbps. The LED on each individual port QSFP+ port indicates the 40-Gbps link status. The lane switch button is illuminated, but none of the four lane LEDs are illuminated.

  • Pressing the lane switch button for the first time causes the lane 1 LED to illuminate. The LED on each individual QSFP+ port represents the lane 1 status of the port.

  • Pressing the lane switch button for the second time causes the lane 2 LED to illuminate. The LED on each individual QSFP+ port represents the lane 2 status of the port.

  • Pressing the lane switch button for the third time causes the lane 3 LED to illuminate. The LED on each individual QSFP+ port represents the lane 3 status of the port.

  • Pressing the lane switch button for the fourth time causes the lane 4 LED to illuminate. The LED on each individual QSFP+ port represents the lane 4 status of the port.

  • Pressing the lane switch button again causes the 40-Gbps mode to be in effect again.

When you cycle the lane switch button, the LED of a QSFP+ port indicates the status of the different lanes. If a port is configured in breakout mode, the LED for a QSFP+ port is off when the lane LEDs are off. If a 40-Gbps port is not operating in breakout mode, and if the link is up, the LED on a QSFP+ port is green when all the lane LEDs are off. The LED turns off when you press the lane button to lane 1, 2, 3, or 4.

The QSFP+ port LEDs for ports 13 and 14 are always the same as the 40-Gbps mode status because those two ports cannot operate in breakout mode.

Connection Ports and LEDs

Both the Cisco UCS 6332 Fabric Interconnect and the UCS 6332-16UP Fabric Interconnect have the connection ports and LEDs shown in the following figure:

Supported Transceivers

The Cisco UCS 6300 Series Fabric Interconnects support SFP+ Ethernet transceivers, SFP transceivers, SFP+ transceivers, SFP+ copper twinax cables with integrated transceivers, SFP Fibre Channel transceivers, QSFP transceivers, and QSFP cables. Except where noted, both the UCS 6332 Fabric Interconnect and the UCS 6332-16UP Fabric Interconnect support all the transceivers listed in this section.

On the Cisco UCS 6332 Fabric Interconnect, all 1-Gigabit and 10-Gigabit transceivers and twinax cables must use a QSA module (CVR-QSFP-SFP10G) to operate in a 40-Gbps QSFP+ port. In addition, the QSA module is required for a 40-Gbps QSFP+ port to operate at 1 Gbps or 10 Gbps.

On the Cisco UCS 6332-16UP Fabric Interconnect, all 1-Gigabit and 10-Gigabit transceivers, Fibre Channel transceivers, and twinax cables must use a QSA module (CVR-QSFP-SFP10G) to operate in ports 17–40 (the 40-Gbps QSFP+ ports). Ports 1–16 operate as SFP+ universal ports that are capable of operating at 1- or 10-Gbps fixed Ethernet or 4-, 8-, or 16-Gbps Fibre Channel ports and do not need a QSFP to SFP+ adapter. In addition, the QSA module is required for a 40-Gbps QSFP+ port to operate at 1 Gbps or 10 Gbps.

SFP 1-Gigabit Transceivers

The SFP 1-Gigabit Ethernet transceiver module is a bidirectional device with a transmitter and receiver in the same physical package.

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 m limit still applies.

SFP+ Transceivers and SFP+ Copper Cables

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.
