Information About Using a Fabric Extender with a Cisco Nexus

5000 Series Switch

The Cisco Nexus 2000 Series Fabric Extenders (FEXs) support Gigabit Ethernet and 10-Gigabit Ethernet

environments while allowing transparent migration to 10-Gigabit Ethernet virtual machine aware unified

fabric technologies. The Cisco Nexus 2000 Series FEXs behave as remote I/O modules for a parent Cisco

Nexus 5000 Series switch. The FEX is an extension of the parent Cisco Nexus switch fabric, with the

FEX and the parent Cisco Nexus switch together forming a virtual modular system.

A Cisco Nexus 2000 Series FEX forwards all the traffic to the parent Cisco Nexus 5000 Switch over

10-Gigabit Ethernet uplinks. Passing all traffic to the parent switch allows traffic to be shaped according

to policies established on the parent Cisco Nexus 5000 Series switch with a single point of management.

Cisco Nexus 2248TP-E

The Cisco Nexus 2248TP-E is a stackable 1 RU 17.2-inch (45 cm) deep FEX that supports 48 1000-TX

host-facing (downlink) ports and 4 10-Gigabit SFP+ network-facing (uplink) ports. You can order it with

front-to-back or back-to-front air cooling, and with AC or DC power supplies.

Chapter 1 Using a Fabric Extender with a Cisco Nexus 5000 Series Switch

Cisco Nexus 2248TP-E

You can use this FEX with the Cisco Nexus 5000 Series switch. The Cisco Nexus 2248TP-E is managed

and configured by the upstream switch. The FEX software ships with the Cisco Nexus 5000 Series

switch software. The FEX downloads the software image from the switch the same way that a module

would download it from the supervisor in a modular chassis.

This section includes the following topics:

•Chassis, page 1-2

•Ports, page 1-3

•Power Supplies, page 1-3

•Fan Trays, page 1-7

•Supported Transceivers and Cables, page 1-9

Chassis

The Cisco Nexus 2248TP-E FEX chassis has a height of 1.72 inches (4.37 cm), a width of 17.3 inches

(43.94 cm), and a depth of 17.7 inches (44.96 cm). It weighs 17.7 pounds (8.0 kg). Its one-rack-unit (1

RU) form factor takes up relatively little space, making it easy to incorporate into rack designs. The FEX

is mounted in a standard 19-inch (48.26 cm) rack. All switch ports at the rear of the unit are in close

proximity to server ports, and all user-serviceable components are accessible from the front panel.

You can order it with front-to-back or back-to-front air cooling, and with AC or DC power supplies. If

you are going to install the chassis with its front end facing the cold aisle, you must order the chassis

with front-to-back air flow. If you are going to install the chassis with its back end facing the cold aisle,

you must order the chassis with back-to-front airflow.

Figure 1-1 shows the location of the components found on the front of the chassis, and Figure 1-2 shows

the location of components found on the rear of the chassis. For information on what the chassis and

component LEDs indicate, see Table D-1 on page D-2.

Chassis

You can order the Cisco Nexus 2248TP-E FEX with AC power supplies that have front-to-back or

back-to-front airflow for cooling or DC power supplies that offer front-to-back airflow. The

back-to-front airflow components have a black stripe on their front surface for easy visual identification.

The front-to-back airflow components do not have a black stripe.

Caution Be sure that all of the power supply and fan tray modules in the same chassis have the same airflow

direction and that the air intake for those modules is positioned on a cool aisle. If you install a module

that uses a different direction of airflow from the other modules in your system, you will see an error

message. If you position a chassis with its modules taking cooling air from a warm aisle, the switch can

reach an overtemperature state and shut down.

If one power supply is installed in the chassis, but the other power supply slot is empty, you should use

a blank filler panel (part number N2200-P-BLNK) to cover the empty slot. Figure 1-7 shows a blank

power supply filler panel.

You can order front-to-back airflow or back-to-front airflow for cooling. If you are going to install the

chassis with its front end facing the cold aisle, you must order the chassis with front-to-back air flow. If

you are going to install the chassis with its back end facing the cold aisle, you must order the chassis

with back-to-front airflow.

Ports

The Cisco Nexus 2248PQ FEX supports a total of 48 1/10-Gigabit Ethernet/Fibre Channel over Ethernet

(FCoE) ports (SFP+) and 4 QSFP+ (16 10-Gigabit ) fabric ports. The Cisco Nexus 2248PQ provides two

types of ports: ports for end-host attachments and uplink ports. Uplink ports are differentiated with

yellow for connectivity to the upstream parent Cisco Nexus 5000 Series switch.

The Cisco Nexus 2248PQ 10GE Fabric Extender supports FCoE and Data Center Bridging (DCB) which

increases the reliability, efficiency, and scalability of Ethernet networks by allowing the switches to

support multiple traffic classes over a lossless Ethernet fabric, enabling consolidation of LAN, SAN, and

cluster environments.

Power Supplies

The Cisco Nexus 2248PQ FEX chassis has two bays for front-end AC or DC power supplies. This chassis

is fully functional with one power supply, but you can install a second power supply for power

redundancy. The power supply is hot swappable during operations.

Table 1-9 lists the power supplies that you can order with the Cisco Nexus 2248PQ FEX.

Figure 1-12 on page 1-12 shows an AC power supply with front-to-back airflow. Figure 1-13 on

page 1-13 shows an AC power supply with back-to-front airflow. Figure 1-14 on page 1-13 shows a DC

power supply with front-to-back airflow.

You can order the Cisco Nexus 2248PQ FEX with AC power supplies that have front-to-back or

back-to-front airflow for cooling or DC power supplies that have front-to-back airflow. The

back-to-front airflow components have a black stripe on their front surface for easy visual identification.

Caution Be sure that all of the power supply and fan tray modules in the same chassis have the same airflow

direction and that the air intake for those modules is positioned on a cool aisle. If you install a module

that uses a different direction of airflow from the other modules in your system, you will see an error

message. If you position a chassis with its modules taking cooling air from a warm aisle, the switch can

reach an overtemperature state and shut down.

If one power supply is installed in the chassis, but the other power supply slot is empty, you should use

a blank filler panel (N2200-P-BLNK) to cover the empty slot. Figure 1-15 on page 1-14 shows a blank

power supply filler panel.

For power supply specifications, see Table B-1 on page B-2. To replace a power supply, see the

“Removing and Installing Power Supplies” section on page 3-17.

Fan Trays

To see the components that you use when installing a power supply unit, see Figure 1-12 on page 1-12

for the AC power supply with front-to-back airflow, Figure 1-13 on page 1-13 for the AC power supply

with back-to-front airflow, and Figure 1-14 on page 1-13 for the DC power supply with front-to-back

airflow.

You can order the Cisco Nexus 2224TP FEX with AC power supplies that have front-to-back or

back-to-front airflow for cooling or DC power supplies that have front-to-back airflow. The

back-to-front airflow components have a black stripe on their front surface for easy visual identification.

The front-to-back airflow components do not have a black stripe.

Caution Be sure that all of the power supply and fan tray modules in the same chassis have the same airflow

direction and that the air intake for those modules is positioned on a cool aisle. If you install a module

that uses a different direction of airflow from the other modules in your system, you will see an error

message. If you position a chassis with its modules taking cooling air from a warm aisle, the switch can

reach an overtemperature state and shut down.

If one power supply is installed in the chassis, but the other power supply slot is empty, you should use

a blank filler panel to cover the empty slot. Figure 1-15 on page 1-14 shows a blank power supply filler

panel.

For power supply specifications, see Table B-1 on page B-2. To replace a power supply, see the

“Removing and Installing Power Supplies” section on page 3-17.

Fan Tray

The Cisco Nexus 2224TP FEX has one fan tray that is hot swappable during operations. Depending on

whether there is a cold aisle in front of or in back of the chassis, you can order front-to-back airflow or

back-to-front airflow for the fan tray and the power supplies in the same chassis. Table 1-19 lists the part

numbers for each of the fan trays that you can use with this chassis.

To see the components used when installing one of these fan trays, see Figure 1-16 (front-to-back

airflow) or Figure 1-17 (back-to-front airflow).

To replace a fan tray, see the “Removing and Installing the Fan Tray” section on page 3-20. For LED

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, page 2-1

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.

You can order the Cisco Nexus 2248TP-E with front-to-back (port-side exhaust) or back-to-front

(port-side intake) airflow and with AC or DC power supplies. If you are going to install the port side in

a hot aisle, then order front-to-back airflow for the fan trays and power supplies. If you are going to

install the port side in the cold aisle, order back-to-front airflow for the fan trays and power supplies.

Note For visual identification, back-to-front airflow power supplies and fan trays have a black stripe across

their front, and front-to-back 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.

Cisco Nexus 2248TP FEX

The Cisco Nexus 2248TP FEX 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. Ta b l e 2 - 3 lists its physical characteristics.

You can order the Cisco Nexus 2248TP with front-to-back (port-side exhaust) or back-to-front (port-side

intake) airflow and with AC or DC power supplies. If you are going to install the port side in a hot aisle,

then order front-to-back airflow for the fan trays and power supplies. If you are going to install the port

side in the cold aisle, order back-to-front airflow for the fan trays and power supplies.

Note For visual identification, back-to-front airflow fan trays and power supplies have a black stripe across

their front, and front-to-back 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 FEX chassis has one or two power supplies, a fan tray, and two

chassis LEDs as shown in Figure 2-13. This FEX model requires one power supply, but if you want

power redundancy, you must install a second power supply.
