Install options with rack-mount kits

The rack-mount kit enables you to install the switch into racks of varying depths. Position the switch with easy access to either the port connections or the fan and power supply modules.

Install the switch using these rack-mount options.

  • Rack-mount kit (NXK-ACC-KIT-1RU) which you can order from Cisco. This option offers you easy installation, greater stability, increased weight capacity, added accessibility, and improved removability with front and rear removal.

    • When installing the NXK-ACC-KIT-1RU rack-mount kit, the distance between the outside face of the front mounting rail and the outside face of the back mounting rail should be 25.37 to 33 inches (64.43 to 83.82 cm) to allow for rear-bracket installation.

  • Rack-mount kit (N3K-C3064-ACC-KIT) which you can order from Cisco.

    • When installing the N3K-C3064-ACC-KIT rack-mount kit, the distance between the outside face of the front mounting rail and the outside face of the back mounting rail should be 22 to 30 inches (55.88 to 76.2 cm) to allow for rear-bracket installation.

The rack or cabinet that you use must meet the requirements listed the in General Requirements for Cabinets and Racks section.


Note

You are responsible for verifying that your rack and rack-mount hardware comply with the guidelines that are described in this document.

Airflow considerations

The switch comes with fan and power supply modules that have either port-side intake or port-side exhaust airflow for cooling the switch.

If you are positioning the port end of the switch in a cold aisle, verify that the switch has port-side intake fan modules with burgundy coloring. If you are positioning the fan and power supply modules in a cold aisle, verify that the switch has port-side exhaust fan modules with blue colorings. All fan modules must have the same direction of airflow.

Guidelines to install the switch

When installing the switch, follow these guidelines.

  • Ensure that there is adequate clearance space around the switch to allow for servicing the switch and for adequate airflow.

  • Ensure that you are positioning the switch in a rack so that it takes in cold air from the cold aisle and exhausts air to the hot aisle. If there is blue coloring on the fan modules, the switch is configured for port-side exhaust airflow and you must position the module side of the switch in a cold aisle. If there is burgundy coloring on the fan modules, the switch is configured for port-side intake airflow and you must position the port side of the switch in a cold aisle.

  • Ensure that the chassis can be adequately grounded. If the switch is not mounted in a grounded rack, we recommend connecting the system ground on the chassis directly to an earth ground.

  • Ensure that the site power meets the power requirements for the switch. If available, use an uninterruptible power supply (UPS) to protect against power failures.


    Note

    Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with the switch, which can have substantial current draw fluctuations because of fluctuating data traffic patterns.

  • • Ensure that circuits are sized according to local and national codes. Typically, this often requires one or both of these:

    • AC power supplies typically require at least a 15-A or 20-A AC circuit, 100 to 240 VAC, and a frequency of 50 to 60 Hz.


      Note

      To prevent loss of input power, ensure the total maximum loads on the circuits supplying power to the switch are within the current ratings for the wiring and breakers.

Unpack and inspect the switch

Before you install a new chassis, unpack and inspect it to be sure that you have all the items that you ordered. Verify that the switch was not damaged during shipment. If anything is damaged or missing, contact your customer representative immediately.


Note

When you handle the chassis or its components, follow ESD protocol at all times to prevent ESD damage. This protocol includes but is not limited to wearing an ESD wrist strap that you connect to the earth ground.


Tip

Do not discard the shipping container when you unpack the switch. Flatten the shipping cartons and store them. If you need to move or ship the system in the future, you will need this container.

Before you begin

Before you unpack the switch and before you handle any switch components, be sure that you are wearing a grounded electrostatic discharge (ESD) strap. To ground the strap, attach it directly to an earth ground or to a grounded rack or grounded chassis (there must be a metal-to-metal connection to the earth ground).

Procedure

Step 1

Compare the shipment to the equipment list that is provided by your customer service representative. Verify that you have received all of the ordered items.

The shipment should include:

  • Switch chassis

Install the switch on an ORV3 rack

Open Rack Version 3 (ORV3) is a specification to build base frames for large scale deployment of racks. ORV3 adheres to the open hardware standards and is compatible with a wide range of IT equipment and facilitates interoperability with other Open Compute Project (OCP)-compliant hardware.

The N9K-9332D-GX2B-ORV3 switch is bundled or pre-installed on a tray to faciliate rack mounting the switch on ORV3 racks.

The tray with the preinstalled switch can be rack mounted on to the ORV3 rack.

Features of the switch preinstalled on the tray

To ensure that the preinstalled switch is compatible with the ORV3 rack,

  • Fans and power supply modules are hot swappable.

  • The serial number barcode and MAC address can be scanned.

  • Option to access RJ-45 Ethernet ports from the front panel of the switch.

  • A converter board to convert +48V busbar on the ORV3 rack to -48V.

    Cisco switches require -48V power source.

  • Inrush current prevention inbuilt into the power supply modules and converter boards to limit electric current spikes.

  • Install your rack in a secure location.

Procedure

Insert the airflow sleeve into the rack and attach it.

  1. Holding the airflow sleeve (N9K-AIRFLOW-SLV) with both hands, position it in front of the fan side of the chassis.

  2. Holding the airflow sleeve level, insert screws (12-24 or 10-32, depending on the rack type) in each of the two front rack-mount flanges (using a total of two screws) and into the cage nuts or threaded holes in the vertical rack-mounting rails (see the figure).


    tighten screws on airflow sleeves

  3. Tighten the 10-32 screws to 20 in-lb (2.26 N·m) or tighten the 12-24 screws to 30 in-lb (3.39 N·m) of torque.

Ground the chassis

The switch chassis is automatically grounded when you properly install the switch in a grounded rack with metal-to-metal connections between the switch and rack.


Note

Provide an electrical conducting path between the product chassis and the metal surface of the enclosure or rack in which it is mounted or to a grounding conductor. To ensure electrical continuity, use thread-forming type mounting screws that remove any paint or non-conductive coatings and establish a metal-to-metal contact. Remove any paint or other non-conductive coatings on the surfaces between the mounting hardware and the enclosure or rack. Clean the surfaces and apply an antioxidant before installation.

If using AC or HVDC power supplies, the power cord for the AC power supplies provides grounding for the chassis. For supplemental grounding or bonding, attach a customer-supplied grounding cable to the chassis ground pad.

Ground the chassis. If you are using a 2-post rack, attach a customer-supplied grounding cable. Attach the cable to the chassis grounding pad and the facility ground. If you are using a 4-post rack, ensure that your chassis is grounded through the rack mount system or the power cable (AC or HVDC).


Warning

This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.


Warning

To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be made first and disconnected last.

If your unit has modules, secure them with the provided screws.

Before you begin

Before you can ground the chassis, verify the earth ground contact has a solid connection to the data center building.

Procedure

Step 1

Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the covering from the end of the grounding wire. We recommend 6-AWG wire for the U.S. installations.

Step 2

Insert the stripped end of the grounding wire into the open end of the grounding lug. Use a crimping tool to crimp the lug to the wire. See the figure. Verify that the ground wire is securely attached to the grounding lug by attempting to pull the wire out of the crimped lug (tug test).

  • Connect the other end of the power cable to a power source.

    • Verify that the power is turned off at a circuit breaker for the power source terminals.

    • Remove the nuts from each of the terminal posts for the power supply.

    • Place the power cable negative-wire terminal ring on the negative terminal for the power source and secure them with a terminal nut.

    • Place the power cable positive-wire terminal ring on the positive terminal for the power source and secure them with a terminal nut.

    • Place the power cable ground-wire terminal ring on the ground terminal for the power source and secure them with a terminal nut.

    • If there is a safety cover for the power source terminals, place and secure it over the terminals to avoid an electrical shock hazard.

    • Turn on the power at the power source circuit breaker.

Step 3

For any DC power supply

  • Turn off the circuit breaker for the power source to avoid an electrical shock hazard.

  • Verify that the power cable wires from the power source are connected to a connector block.

  • Insert the connector block into the receptacle on the power supply. Make sure that the connector block clicks when fully inserted in the receptacle and does not pull out.

  • If there is a safety cover for the terminals, place and secure it over the terminals to avoid an electrical shock hazard.

  • Turn on the power at the circuit breaker for the DC power source.

Step 4

Verify that the power supply LED is on and green.

Step 5

Listen for the fans; they should begin operating when the power supply is powered.

Step 6

After the switch boots, verify that the following LEDs are lit.

  • On the fan modules, the Status (STA or STS) LED is green.

    If a fan module Status LED is not green, try reinstalling the fan module.

  • After initialization, the switch chassis Status (labeled as STA or STS) LED is green.

Step 7

Verify that the system software has booted and the switch has initialized without error messages.

A setup utility automatically launches the first time that you access the switch and guides you through the basic configuration. For instructions on how to configure the switch and check module connectivity, see the appropriate Cisco N9000 Series Configuration Guides.
