Overview

This chapter provides an overview of the Cisco Nexus 7000 Series switch and includes the following sections:

Cisco Nexus 7000 Series

The Cisco Nexus 7000 Series switches are multiprotocol-capable, high-density, and high-performance switches that incorporate Ethernet/IP, virtualization, Layer 4 to Layer 7 services, and low-latency interconnect (LLI) technologies. The Cisco Nexus 7000 Series models are described in the following topics:

Cisco Nexus 7004 Switch

The Cisco Nexus 7004 chassis has four slots that allow for one or two supervisor modules and up to two I/O modules. Additionally, the chassis holds a fan tray, up to four power supplies, and cable management frames. Optionally, you can include a door and air filter. Figure 1-1 identifies these features as seen from the front of the chassis.

Handles used for moving the chassis (reduce the chassis weight to less than 120 lbs (54.4 kg) in order to use these handles to lift the chassis)

4

I/O or NAM modules (1 to 2 modules in slots 3 to 4).

7

Air intake areas for supervisor and I/O modules

4

Supervisor modules (1 or 2 modules in slots 1 and 2). These modules are of only one of the following types (if installing two supervisor modules, both modules must be the same type with the same amount of memory):

  • Supervisor 2 (N7K-SUP2)
  • Supervisor 2 Enhanced (N7K-SUP2E)

 


Note Figure 1-1 shows the Cisco Nexus 7004 chassis as it appears when it is fully configured before including cables for management and network connections. The systems that are not fully configured with the maximum number of supervisor modules, I/O modules, or power supply units have blank panels installed in place of the missing components to maintain the designed airflow for system cooling.


The I/O module slots hold one or two of the following types of modules:

  • F2 Series I/O modules

48-port 1-/10-Gigabit SFP+ with XL option and FEX support (N7K-F248XP-25 and N7K-F248XP-25E1)

2-port 100-Gigabit Ethernet with XL option (N7K-M202XP-23L)

  • Network Analysis modules (N7K-SM-NAM-K9)

You must install the Cisco Nexus 7004 chassis in a two- or four-post 19-inch EIA rack that meets the following specifications:

  • Mounting rails that conform to the English universal hole spacing as specified in ANSI/EIA-310-D-1992.
  • The minimum vertical rack space is 12.25 inches (31.1 cm) or 7 rack units (RU) for a single chassis installation.

Install the Cisco Nexus 7004 chassis at the lowest possible RU on the rack for stability. If there are other devices in the rack, install the heavier chassis below the lighter chassis.


Warning Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over. Statement 1048


Cisco Nexus 7009 Switch

The Cisco Nexus 7009 chassis has 9 slots that allow for one or two supervisor modules and up to seven I/O modules. Additionally, the chassis also holds up to five fabric modules, one fan tray, up to two power supplies, and cable management frames. The chassis also has a front-mount bracket (an alternative center-mount bracket can be ordered) and four positioning handles (two on each side) that you use to position the chassis after you place it on a mechanical lift or bottom-support brackets. Optionally, you can include a door and air intake frame.

Figure 1-2 identifies the standard features on the front and sides of the Cisco Nexus 7009 chassis, and Figure 1-3 identifies the standard features on the rear of the chassis.

Preparing the Site


Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074


Before you can install a Cisco Nexus 7000 Series system, you must prepare the site for the installation. You must make sure that the altitude, temperature, humidity, air quality, airflow, electromagnetic and radio frequency interference, floor structure, power, and earth grounding of the installation site all meet the requirements of the Cisco Nexus 7000 Series system that you are installing. In addition, you must set up a rack or cabinet that can hold the number of chassis that you are installing. To see the general requirements for this system, see Appendix A, “Technical Specifications.” To see detailed information about preparing the data center for the installation, see the Cisco Nexus 7000 Series Site Preparation Guide .

Safety Guidelines


Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030


The prerequisites listed for any procedure are required conditions that you must verify before you start that procedure. If the prerequisites have not been met, you must satisfy those requirements before carrying out the procedure.

Safety warnings appear in this publication wherever procedures present conditions that could endanger you or others installing this system. Adhering to these warnings and following their recommended actions are required actions for these procedures. For regulatory compliance and safety information on these warnings, see the Cisco Nexus 7000 Series Regulatory Compliance and Safety Information document.

Installation and Connection Guidelines

After you fully prepare the site as specified in the Cisco Nexus 7000 Series Site Preparation Guide , install a two-post 19-inch EIA rack for Cisco Nexus 7004 and 7009 chassis or a four-post 19-inch EIA rack for all chassis. To install the system, you must make sure that you have the proper mounting brackets (front-mount or center-mount brackets) installed on the chassis, move the chassis to the rack, elevate it to the lowest possible RU for that chassis, and fasten the chassis to the rack. With the chassis fastened to the rack, you can ground the chassis, install its cable management frames, install the optional door and optional air filter, and connect the switch to the console and network. For detailed instructions on installing a Cisco Nexus 7000 Series switch, see the following chapters:

For detailed instructions on connecting the switch to the console and network, see Chapter7, “Connecting the Cisco Nexus 7000 Series Switch to the Network”


Caution Do not use the handles on the side of the chassis to lift the Cisco Nexus 7009, 7010, or 7018 chassis or a fully loaded Cisco Nexus 7004 chassis (you can use these handles to lift a Cisco Nexus 7004 chassis if you remove the power supplies so that the chassis weighs less than 120 pounds [52 kg]). For the Cisco Nexus 7009, 7010, and 7018, use these handles only for adjusting the position of the chassis while the chassis rests on a platform or bottom-support rails.

If you are replacing Fabric 1 modules with Fabric 2 modules (Cisco Nexus 7010 and 7018 models only), you must replace all of the Fabric 1 modules with Fabric 2 modules or the Fabric 2 modules will perform like Fabric 1 modules. If you power up a switch with both Fabric 1 and Fabric 2 modules installed, only the Fabric 2 modules will power up.


Note The Cisco NX-OS software may require 8 GB of memory, depending on the software version you use and the software features that you enable. If your switch has Supervisor 1 modules with only 4 GB of memory, then you might need to upgrade the modules to 8 GB of memory by using the 8 GB supervisor upgrade kit (N7K-SUP1-8GBUPG=). This upgrade is not needed for switches that have at least 8 GB of memory (which includes Supervisor 1 modules with 8 GB and all Supervisor 2 and Supervisor 2E modules). To verify the amount of memory installed in the supervisor modules or to upgrade the memory, see the “Upgrading Memory for Supervisor 1 Modules” section.


Managing the System Hardware

After the Cisco Nexus 7000 Series system is installed and operating, you can use the Cisco NX-OS operating system to manage the system hardware. These management functions include displaying system and module information, setting the power supply modes, and managing module functions. For more information about these functions, see Chapter8, “Managing the Switch Hardware”

Replacing Components

While the Cisco Nexus 7000 Series system is operational, you can replace any one of the following components if they are redundant:

  • Power supply
  • Supervisor module
  • Fabric module (Cisco Nexus 7009, 7010, and 7018 models only)
  • I/O modules
  • Fan trays

For detailed information on replacing these components, see Chapter10, “Installing or Replacing Components”
