The following are guidelines for grounding the fabric interconnect. When installing or replacing the unit, the ground connection must always be made first and disconnected last. The plug-socket combination must be accessible at all times, because it serves as the main disconnecting device. All power supplies must be grounded. The receptacles of the AC power cables used to provide power to the fabric interconnect must be the grounding type, and the grounding conductors should connect to protective earth ground at the service equipment.
Grounding the fabric interconnect is required if you are using DC power supplies, even if the rack is already grounded. A grounding pad with two threaded M4 holes is provided on the fabric interconnect for attaching a grounding lug. The ground lug must be NRTL listed. In addition, the copper conductor wires must be used and the copper conductor must comply with NEC code. Use a wire-stripping tool to remove approximately 0. Insert the stripped end of the grounding cable into the open end of the grounding lug.
Grounding pad on FI, with two M4-threaded screw holes enlarged view shown. Place the grounding lug against the grounding pad so that there is solid metal-to-metal contact, and insert the two M4 screws through the holes in the grounding lug and into the grounding pad.
Prepare the other end of the grounding cable and connect it to an appropriate grounding point in your site to ensure adequate earth ground. The chassis is automatically grounded when you properly install the FI in a grounded rack with metal-to-metal connections between the chassis and rack. You can also ground the chassis, which is required if the rack is not grounded, by attaching a customer-supplied grounding cable.
Attach the cable to the chassis grounding pad and the facility ground. Before you can ground the chassis, you must have a connection to the earth ground for the data center building. Ensure you have the proper grounding cable and grounding wire as appropriate for you country or region. We recommend 6-AWG wire for the U. Insert the stripped end of the grounding wire into the open end of the grounding lug.
The grounding lug is on the front plate of the FI. To identify the location of the grounding lug, see Figure 2. Use a crimping tool to crimp the lug to the wire, see the following figure. Verify that the ground wire is securely attached to the grounding lug by attempting to pull the wire out of the crimped lug.
Secure the grounding lug to the chassis grounding pad with two M4 screws, see the previous figure. Tighten the screws to 11 to 15 in-lb 1. Prepare the other end of the grounding wire and connect it to the facility ground. Do not connect the Ethernet port to the LAN until the initial system configuration has been performed.
Depending on the outlet receptacle on your power distribution unit, you may need the optional jumper power cord to connect the Cisco UCS Fabric Interconnect to your outlet receptacle.
See Cabinet Jumper Power Cords. Ensure that the chassis is adequately grounded, and that the AC or DC power available has the required power voltages see Power Specifications. For a first-time installation, you will need to work with your network manager to determine the following parameters:.
Password for the admin account. This password can not be blank. Connect a PC or laptop directly to the local console port of the primary or standalone fabric interconnect. In a cluster configuration, the primary is the fabric interconnect that powers up first. The console port on the terminal should be set to baud, 8 data bits, no parity, 1 stop bit.
If the fabric interconnect will be running in a cluster with another fabric interconnect, connect Ethernet cables between the L1 and L2 ports. If the fabric interconnect and the UCS instance will be in standalone mode, this step is not necessary.
Connect the power cable to a power source. The system should power on as soon as you connect the cable. After initialization, the system status LED is green, indicating that all chassis environmental monitors are reporting that the system is operational. If this LED is orange or red, then at least one environmental monitor is reporting a problem. The link LEDs for the Fibre Channel ports remain yellow until the ports are enabled, and the LED for an Ethernet connector port remains off until the port is connected.
If there is a problem, 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. If you purchased this product through a Cisco reseller, contact the reseller directly for technical support.
Verify that the system software has booted and that the system has initialized without error messages. Complete the worksheets provided in Site Preparation Checklist for future reference. Configure the primary fabric interconnect as described in thr Configuration Guide for the version of Cisco UCS Manager that you are using.

Note In all situations, grounding practices must comply with local National Electric Code NEC requirements or local laws and regulations. Removing a subordinate standby fabric interconnect is non-disruptive in a redundant, high-availability Cisco UCS configuration. Removing a primary active fabric interconnect will cause the standby fabric interconnect to become active with minimal or no disruption.
When powering down and removing clustered fabric interconnects, remove the subordinate fabric interconnect first, and then remove the primary fabric interconnect. Be aware that if you remove both the primary and subordinate fabric interconnects, or the single fabric interconnect from a standalone system, you are shutting down the entire Cisco UCS domain.
Use the following procedure when you need to replace a single fabric interconnect with the same model of fabric interconnect. As a best practice, perform a full configuration backup before replacing the fabric interconnect. Contact Cisco TAC or your Cisco Sales representative to have them transfer the license to the replacement fabric interconnect. Label the ports and the cables that you using so that you can refer to this information later.
The cabling and port numbering should be same for the replacement fabric interconnect. From the CLI, enter the show cluster extended-state command. Use the fabric evacuation procedure on the subordinate fabric interconnect to ensure there is no data traffic impact during the hardware replacement. Power down the subordinate fabric interconnect by unplugging it from the power source.
Remove the fabric interconnect from the rack. Install the replacement fabric interconnect to the rack. Connect the power cable to the fabric interconnect and it will automatically boot and run POST tests.
If necessary, upgrade the UCS Manager software. If the replacement fabric interconnect is not running the same firmware version as the cluster, the setup utility can upgrade the firmware. Enter the show cluster extended-state command to revalidate the cluster state and verify that HA is ready. Disable fabric evacuation and verify that traffic is flowing in both fabric interconnects. Support both sides of the fabric interconnect when removing it from the rack.
The slider rail and front rack-mount brackets do not have a stop mechanism. If the front of the chassis is unfastened from the rack and the chassis slides forward on the slider rails, it may slip off the end of the rails and fall out of the rack.
Ensure that the weight of the Cisco UCS Fabric Interconnect is fully supported and that the chassis is being held by another person. Be aware that if you remove both the active and standby fabric interconnect, or the sole fabric interconnect from a standalone system, you are shutting down the entire Cisco UCS domain.
Decommission every attached chassis in the Cisco UCS domain. When powering down and removing clustered fabric interconnects, remove the secondary first, and then remove the primary. The slider rail and front rack-mount brackets do not have a stop mechanism when sliding in and out. If the front of the chassis is unfastened from the rack and the chassis slides forward on the slider rails, it may slip off the end of the rails and fall out of the rack.
Ensure that the weight of the Cisco UCS UP is fully supported and that the chassis is being held by another person. Remove the two screws holding the grounding cable to the chassis.
Disconnect the power cord and the console cables. Remove the screws fastening the front rack-mount brackets to the mounting rails. Ensure that the weight of the Cisco UCS is fully supported and that the chassis is being held by another person. Gently slide the Cisco UCS toward you, off of the slider rails and out of the rack.
Use the following procedure when you need to replace a single fabric interconnect with the same model of fabric interconnect. As a best practice, perform a full configuration backup before replacing the fabric interconnect. Contact Cisco TAC or your Cisco Sales representative to have them transfer the license to the replacement fabric interconnect. Label the ports and the cables that you using so that you can refer to this information later. The cabling and port numbering should be same for the replacement fabric interconnect.
Log into UCS Manager and verify the state of the fabric interconnect, either active or subordinate. From the CLI, enter the show cluster extended-state command. Use the fabric evacuation procedure on the subordinate fabric interconnect to ensure there is no data traffic impact during the hardware replacement.
Power down the subordinate fabric interconnect by unplugging it from the power source. Disconnect the cables from the front and back of the fabric interconnect and remove it. Follow the instructions in this section for removing a fabric interconnect. Install the replacement fabric interconnect. Follow the instructions in this section for installing the fabric interconnect. Connect the management and console cables to the replacement fabric interconnect. Connect the data cable according to the labels that you created in Step 2.
Connect the power cable to the fabric interconnect and it will automatically boot and run POST tests. If necessary, upgrade the UCS Manager software. If the replacement fabric interconnect is not running the same firmware version as the cluster, the setup utility can upgrade the firmware.
Enter the show cluster extended-state command to revalidate the cluster state and verify that HA is ready. Disable fabric evacuation and verify that traffic is flowing in both fabric interconnects. Apply the port license to the fabric interconnect. Make a detailed record of the cabling between FEXes and fabric interconnects. You must preserve the physical port mapping to maintain the server pinning already configured and to minimize downtime.
As a best practice, perform a Full State backup and All Configuration backup before performing the upgrade. Correct the faults if needed. Be prepared to compare the list of faults the any faults that are present following the migration. They should be the same as before the migration. Check the data path for both Ethernet forwarding and Fibre Channel traffic. Mount the replacement fabric interconnect into either the same rack or an adjacent rack.
Back up all software configuration information, including state and system configuration. Follow the Fabric Evacuation procedure on the subordinate fabric interconnect to ensure there is no data traffic impact during the upgrade.
Enter the unconfigure all server ports command to remove the configuration from the server ports in the subordinate fabric interconnect. It will automatically boot and run POST tests.
Enable and configure all uplink ports and verify connectivity to network uplinks. Enable and configure the server ports that were unconfigured in Step 5. Clear any faults related to failover or data path. If possible, use the original packing materials and container to repack the chassis. Contact your Cisco customer service representative to arrange for return shipment to Cisco.
