THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMA TION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELI EVED TO BE ACCURATE BUT ARE PRE SENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following infor mation is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-fre quency energy . If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and yo u may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

CHAPTER

Using a Fabric Extender with a Cisco Nexus 5000 Series Switch

This chapter describes the Cisco Nexus 2000 Series Fabric Extenders (FEXs) and includes these sections:

• Cisco Nexus 2248TP-E, page 1-1

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.

Chassis

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

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

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.

Ports

The Cisco Nexus 2248TP-E FEX supports a total of 48 100/1000BASE-T ports and four 10-Gigabit Ethernet uplinks (SFP+). It provides two types of ports: host-facing downlink ports and network-facing uplink ports. Uplink ports are colored with yellow for connectivity to the upstream parent Cisco Nexus 5000 Series switch.

Power Supplies

The Cisco Nexus 2248TP-E 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- 1 lists the power supplies that you can order with the Cisco Nexus 2248TP-E FEX.

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.

Fan Trays

The Cisco Nexus 2248TP-E FEX has one fan tray that is hot swappable during operations. Depending on the arrangement of hot and cold aisles in your data center, you can order front-to-back airflow to position the front of the FEX chassis in a cold aisle or back-to-front airflow to position the back of the FEX chassis in a cold aisle. Tabl e 1-2 lists the part numbers for each of the fan trays that you can use with the Cisco Nexus 2248TP-E chassis.
