Using a Fabric Extender with a Cisco Nexus 7000 Series Switch

This chapter describes the Cisco Nexus 2200 Platform Fabric Extender (FEX) chassis and the components that you can connect to a Cisco Nexus 7000 Series switch. This chapter includes the following sections:

Information About Using a Fabric Extender with a Cisco Nexus 7000 Series Switch

You can extend the Cisco Nexus 7000 Series switch architecture by connecting up to 32 FEXs as remote I/O modules. Depending on which FEX model that you connect to the switch, the FEX provides top-of-the-rack connectivity for up to 48, 32, or 24 hosts, and it becomes an extension of the parent Cisco Nexus 7000 Series switch fabric, with the FEX and the switch becoming a virtual modular system. The FEX forwards all 100/1000 Ethernet or 1- and 10-Gigabit Ethernet traffic from the hosts to the switch over 10-Gbps uplinks. Traffic flows from the switch to the FEX over the 10-Gbps uplinks and to the individual hosts over 100/1000 Ethernet or 1- and 10-Gigabit Ethernet downlinks.

You connect a FEX uplink port to the Cisco Nexus 7000 Series switch through one of the following Ethernet I/O modules installed in the switch:

  • F2 Series 48-port 1 or 10-Gigabit Ethernet I/O module (N7K-F248XP-25)
  • M1 Series 32-port 10-Gigabit Ethernet I/O module (N7K-M132XP-12)
  • M1 Series 32-port 10-Gigabit Ethernet I/O module with XL option (N7K-M132XP-12L)
  • M2 Series 24-port 10-Gigabit Ethernet I/O module (N7K-M224XP-23L)

Cisco Nexus 2248TP-E FEX

The Cisco Nexus 2248TP-E FEX (N2K-C2248TP-E) is a stackable 1-RU FEX that has 48 100/1000 Ethernet host-facing (downlink) ports and four 10-Gigabit Ethernet network-facing (uplink) ports. It requires a 19-inch (48.26 cm) rack for its installation. Table 2-1 lists its physical characteristics.

1.Measured with two power supplies and one fan module installed.

You can order the Cisco Nexus 2248TP-E with port-side exhaust or back-to-front airflow and with AC or DC power supplies. If you are going to install the port side in a hot aisle, then order port-side exhaust airflow for all of the fan trays and power supplies. If you are going to install the port side in the cold aisle, order port-side intake airflow for the fan trays and power supplies.


Note For visual identification, port-side exhaust airflow power supplies and fan trays have a black stripe across their front, and port-side intake airflow modules do not have a black stripe across their front. All of the power supplies and fan trays must have the same direction of airflow for the components to properly function (all of these components must either have a black stripe or all of the components must not have a black stripe).


The front of the Cisco Nexus 2248TP-E FEX chassis has one or two power supplies, a fan tray, and two chassis LEDs as shown in Figure 2-1. This FEX model requires one power supply, but if you want power redundancy, you must install a second power supply.

Note For a fully dedicated 10-Gbps bandwidth through a M1 Series 32-port 10-Gigabit Ethernet I/O module (either the N7K-M132XP-12 or N7K-M132XP-12L), connect each FEX to one port in a set of four shared ports on the module (you connect each set of shared ports to one FEX). If you are using the M2 Series 24-port, 10-Gigabit Ethernet I/O module (N7K-M224XP-23L), you can connect the FEX to any of its ports for a fully dedicated bandwidth. If you are using the F2 Series 48-port, 10-Gigabit Ethernet I/O module (N7K-F248XP-25), use the connectivity rule order (connect the same port numbers for each port group (for example, if you connect ports 1 and 2 of a port-group, then connect the same ports of another port group).


For information about the transceivers and connectors that you can use with these ports, see the “Transceivers and Connectors Supported by the Cisco Nexus 2248TP-E FEX” section.

Power Supplies for the Cisco Nexus 2248TP-E FEX

The Cisco Nexus 2200 Series FEX chassis have two slots for front-end AC or DC power supplies that have port-side exhaust or port-side intake airflow. These chassis are fully functional with one power supply, but you can install a second power supply for power redundancy. If you have only one power supply in the chassis, install a blank filler panel (N2200-P-BLNK) to maintain the designed airflow in the chassis. You can install any of the following power supplies in those two bays:

  • AC power supply with port-exhaust airflow (N2200-PAC-400W)
  • AC power supply with port-side intake airflow (N2200-PAC-400W-B)
  • DC power supply with port-side exhaust airflow (N2200-PDC-400W)
  • DC power supply with port-side intake airflow (N2200-PDC-350W-B)

Caution Make sure that all of the fan tray and power supply modules use the same airflow direction and have the same color designation on the front. Otherwise, the switch can over heat and shut down,

Figure 2-4 shows the exterior components on an AC power supply with port-side exhaust airflow (no black stripe on the front). Figure 2-5 shows the components on a DC power supply with port-side exhaust airflow. Figure 2-6 shows the black stripe used to indicate port-side intake airflow (in this case on an AC power supply). Figure 2-7 shows the blank filler panel that you should install in an open power supply slot if the chassis has only one power supply.

Note For a fully dedicated 10-Gbps bandwidth through a M1 Series 32-port 10-Gigabit Ethernet I/O module (either the N7K-M132XP-12 or N7K-M132XP-12L), connect each FEX to one port in a set of four shared ports on the module (you connect each set of shared ports to one FEX). If you are using the M2 Series 24-port, 10-Gigabit Ethernet I/O module (N7K-M224XP-23L), you can connect the FEX to any of its ports for a fully dedicated bandwidth. If you are using the F2 Series 48-port, 10-Gigabit Ethernet I/O module (N7K-F248XP-25), use the connectivity rule order (connect the same port numbers for each port group (for example, if you connect ports 1 and 2 of a port-group, then connect the same ports of another port group).


For information about the transceivers and connectors that you can use with these ports, see the “Transceivers Supported by the Cisco Nexus 2232PP FEX” section.

Power Supplies for the Cisco Nexus 2232PP FEX

The Cisco Nexus 2200 Platform FEX chassis have two slots for front-end AC or DC power supplies that have port-side exhaust or port-side intake airflow. These chassis are fully functional with one power supply, but you can install a second power supply for power redundancy. You can install any of the following power supplies in those two bays:

  • AC power supply with port-side exhaust airflow (N2200-PAC-400W)
  • AC power supply with port-side intake airflow (N2200-PAC-400W-B)
  • DC power supply with port-side exhaust airflow (N2200-PDC-400W)
  • DC power supply with port-side intake airflow (N2200-PDC-350W-B)

Caution Make sure that all of the fan tray and power supply modules use the same airflow direction and have the same color designation on the front. Otherwise, the switch can over heat and shut down,

For information on these power supplies, see the “Power Supplies for the Cisco Nexus 2248TP FEX” section and the power supply specifications in the “Technical Specifications” section.

Fan Tray for the Cisco Nexus 2232PP FEX

The Cisco Nexus 2232PP and 2232TM FEX use the same fan tray, which you can order with either port-side exhaust airflow (N2K-C2232-FAN) or port-side intake airflow (N2K-C2232-FAN-B).


Caution Make sure that all of the fan tray and power supply modules use the same airflow direction and have the same color designation on the front. Otherwise, the switch can over heat and shut down,
