This section describes how to use the rack-mount kit provided with the switch to install the Cisco Nexus 6000 switch into a cabinet or rack that meets the requirements described in Appendix A, “Cabinet and Rack Installation.”
The table below lists the items contained in the rack-mount kit provided with the Cisco Nexus 6004 switch.
Note You must supply the 24 screws required to mount the rack brackets and slider rails to the rack. The rack-mount kit does not provide these screws.
To install the switch in a rack or cabinet using the rack-mount kit provided with the switch, follow these steps:
Step 1 Install the front rack-mount brackets on the chassis as follows:
a. Position a front rack-mount bracket on the side of the chassis with its four holes aligned to four of the six screw holes on the front side of the chassis, and then use four M4 screws to attach the bracket to the chassis.
Note You can align any four of the holes in the front rack-mount bracket to four of the six screw holes in the chassis. The holes that you use depend on the requirements of your rack.
b. Repeat Step 1a with the other front rack-mount bracket on the other side of the switch.
Step 2 Install the rear rack-mount guides on the chassis as follows:
a. Position a rear rack-mount bracket on the side of the chassis with its four holes aligned to four of the six screw holes on the side of the chassis, and then use four M4 screws to attach the bracket to the chassis.
b. Repeat Step 2a with the other rear rack-mount bracket on the other side of the switch.
Step 3 Install the slider rails to the rack as follows:
a. Position the slider rails at the desired level on the back side of the rack and use two 12-24 screws or two 10-32 screws, depending on the rack thread type, to attach the rails to the rack.
Note For racks with square holes, you might need to position a 12-24 cage nut behind each mounting hole in a slider rail before using a 12-24 screw.
b. Repeat with the other slider rail on the other side of the rack.
c. Use the tape measure and level to verify that the rails are at the same height and horizontal.
Step 4 Insert the switch into the rack and attach it as follows:
a. Holding the switch with both hands, position the back of the switch between the front posts of the rack.
b. Align the two rear rack-mount guides on either side of the switch with the slider rails installed in the rack. Slide the rack-mount guides onto the slider rails, and then gently slide the switch all the way into the rack. The Cisco Nexus 6004 chassis slider rails are shown in Figure 2-1.
Note If the switch does not slide easily, try realigning the rack-mount guides on the slider rails.
c. Holding the chassis level, insert two screws (12-24 or 10-32, depending on the rack type) through the cage nuts and the holes in one of the front rack-mount brackets and into the threaded holes in the rack-mounting rail.
d. Repeat for the other front rack-mount bracket on the other side of the switch.
This section describes the need for system grounding for all of the Cisco Nexus 6000 switch and explains how to prevent damage from electrostatic discharge.
This section includes the following topics:
Grounding is one of the most important parts of equipment installation. Proper grounding practices ensure that the buildings and the installed equipment within them have low-impedance connections and low-voltage differentials between chassis. When you properly ground systems during installation, you reduce or prevent shock hazards, equipment damage due to transients, and data corruption. Table 2-2 lists some general grounding practice guidelines.
Note In all situations, grounding practices must comply with local National Electric Code (NEC) requirements or local laws and regulations.
Note Always ensure that all of the modules are completely installed and that the captive installation screws are fully tightened. In addition, ensure that all I/O cables and power cords are properly seated. These practices are normal installation practices and must be followed in all installations.
Electrostatic discharge (ESD) damage, which can occur when modules or other FRUs are improperly handled, results in intermittent or complete failures. Modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, always use an ESD grounding strap when handling modules.
For preventing ESD damage, follow these guidelines:
Note This system ground is also referred to as the network equipment building system (NEBS) ground.
Note You do not need to attach a supplemental system ground wire to the system ground lug; the lug provides a direct path to the bare metal of the chassis.
After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:
Step 1 Attach the ESD wrist strap to bare skin as follows:
a. If you are using the ESD wrist strap supplied with the FRUs, open the wrist strap package and unwrap the ESD wrist strap. Place the black conductive loop over your wrist and tighten the strap so that it makes good contact with your bare skin.
b. If you are using an ESD wrist strap equipped with an alligator clip, open the package and remove the ESD wrist strap. Locate the end of the wrist strap that attaches to your body and secure it to your bare skin.
Step 2 Grasp the spring or alligator clip on the ESD wrist strap and momentarily touch the clip to a bare metal spot (unpainted surface) on the rack. We recommend that you touch the clip to an unpainted rack rail so that any built-up static charge is then safely dissipated to the entire rack.
Step 3 Attach either the spring clip or the alligator clip to the ground lug screw as follows:
a. If you are using the ESD wrist strap that is supplied with the FRUs, squeeze the spring clip jaws open, position the spring clip to one side of the system ground lug screw head, and slide the spring clip over the lug screw head so that the spring clip jaws close behind the lug screw head.
Note The spring clip jaws do not open wide enough to fit directly over the head of the lug screw or the lug barrel.
b. If you are using an ESD wrist strap that is equipped with an alligator clip, attach the alligator clip directly over the head of the system ground lug screw or to the system ground lug barrel.
To attach the ESD wrist strap to the system ground lug screw for any of the Cisco Nexus 6000 switches, clip the grounding wire to the screw that attaches the grounding lug to the switch chassis.
In addition, follow these guidelines when handling modules:
This section describes how to connect a system ground to the Cisco Nexus 6000 Series switch.
You must use the system ground on AC-powered systems if you are installing this equipment in a U.S. or European Central Office.
The system ground provides additional grounding for EMI shielding requirements and grounding for the low-voltage supplies (DC-DC converters) on the modules and is intended to satisfy the Telcordia Technologies requirements for supplemental bonding and grounding connections. You must observe the following system grounding guidelines for your chassis:
To connect the system ground, you need the following tools and materials:
The chassis has a grounding pad with two threaded M4 holes for attaching a grounding lug. The location of the system ground on the Cisco Nexus 6000 switch is similar to that on the Cisco Nexus 5500 Platform switches.
Note For the procedure on how to ground the Cisco Nexus 6000 Series switch chassis, see the “Grounding the Cisco Nexus 6000 Series Chassis” section.
Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046
Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last.
Statement 1046
To attach the grounding lug and cable to the chassis, follow these steps:
Step 1 Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of the grounding cable.
Step 2 Insert the stripped end of the grounding cable into the open end of the grounding lug.
Step 3 Use the crimping tool to secure the grounding cable in the grounding lug.
Step 4 Remove the adhesive label from the grounding pad on the chassis.
Step 5 Place the grounding lug against the grounding pad so that there is solid metal-to-metal contact, and insert the two M4 screws with washers through the holes in the grounding lug and into the grounding pad.
Step 6 Ensure that the lug and cable do not interfere with other equipment.
Step 7 Prepare the other end of the grounding cable and connect it to an appropriate grounding point in your site to ensure adequate earth ground.
This section provides instructions for powering up the Cisco Nexus 6000 switch and verifying the component installation.

For instructions on connecting to the console port, see the “Connecting to the Console Port” section.
Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last.
Statement 1046
To power up the switch and verify hardware operation, follow these steps:
Step 1 Verify that empty power supply slots have filler panels installed, the faceplates of all modules are flush with the front of the chassis, and the captive screws of the power supplies, fan module, and all expansion modules are tight.
Step 2 Verify that the power supply and the fan modules are installed.
Note Depending on the outlet receptacle on your power distribution unit, you may need the optional jumper power cord to connect the switch to your outlet receptacle. See the “Jumper Power Cord” section.
Step 3 Ensure that the switch is adequately grounded as described in the “Grounding the Switch” section, and that the power cables are connected to outlets that have the required AC power voltages (see the “Power Specifications” section).
Step 4 For the switch, insert each end of the power clip (from the accessory kit) into holes on tabs located on either side of the power connectors.
Step 5 Connect each power cable to the power connectors on the chassis and an AC power source. Press the power cable into the power clip to endure that the power cable stays connected to the chassis when bumped. The switch should power on as soon as you connect the power cable.
Step 6 Listen for the fans; they should begin operating when the power cable is plugged in.
Step 7 After the switch boots, verify that the LED operation is as follows:
Note The link LEDs for the Fibre Channel ports remain yellow until the ports are enabled, and the LED for the Ethernet connector port remains off until the port is connected.
Step 8 Try removing and reinstalling a component that is not operating correctly. If it still does not operate correctly, contact your customer service representative for a replacement.
Note If you purchased this product through a Cisco reseller, contact the reseller directly for technical support. If you purchased this product directly from Cisco, contact Cisco Technical Support at this URL: http://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html.
Step 9 Verify that the system software has booted and the switch has initialized without error messages.
If you cannot resolve an issue, contact your customer service representative.
Step 10 Complete the worksheets provided in Appendix G, “Site Planning and Maintenance Records” for future reference.

In a standard airflow configuration, cold air intake is from the fan side and hot air exhaust is from the port side. In a reverse airflow configuration, the cold air intake is from the port side and hot air exhaust is from the fan side. A reverse air flow system must have new reverse air flow fans (four sets), new reverse power supplies, and four reconfigured fan louvers.
A reverse airflow power supply is identified by a black colored stripe. A standard airflow power supply does not have a black colored stripe.
A reverse airflow fan tray (N6K-C6004-FAN-B) is identified by a black colored label near the STAT button. A standard airflow fan tray (N6K-C6004-FAN-F) is identified by a gray colored label near the status LED.
A reverse airflow configuration for an airflow shutter or fan louver (part number 800-38434-03), is identified by a black band that is visible when the fan tray is removed. It also has direction arrows engraved on the top side that should point towards the fan trays. A standard airflow configuration for a fan louver (part number 800-38434-03), is identified by a metallic band that is visible when the fan tray is removed. In this configuration the direction arrows on the top side should point towards the port side. A standard airflow configuration and reverse airflow configuration for louvers are shown in Figure 2-2.
