The fan module is designed to be removed and replaced while the system is operating without presenting an electrical or thermal hazard or damage to the system, provided that the replacement is performed promptly.
When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the fan blades completely stop before you remove the fan tray. Loosen the captive screws on the fan module by turning them counterclockwise, using a flat-blade or number 2 Phillips head screwdriver if required.
Grasp the handle of fan module and pull it outward. Pull the fan module clear of the chassis and set it down on antistatic foam or place it in an antistatic bag.
Hold the replacement fan module with the LED at the bottom. Place the fan module into the front chassis cavity so it rests on the chassis, and then push the fan module into the chassis as far as it can go and the captive screw makes contact with the chassis, and tighten the captive screw.
Listen for the fans if the system is powered on. You should immediately hear them operating. If you do not hear them, ensure that the fan module is inserted completely in the chassis and the faceplate is flush with the outside surface of the chassis.
Verify that the LED is green. If the LED is not green, one or more fans are faulty. If this occurs, contact your customer service representative for a replacement part. Removing a standby fabric interconnect is non-disruptive in a redundant Cisco UCS configuration. Removing an active fabric interconnect will cause the standby fabric interconnect to become active with minimal or no disruption. 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.

Figure 6. Attaching the Switch to the Rack Proper Grounding Practices Grounding is one of the most important parts of equipment installation. Table 3. High All lightning protection devices must be installed in strict accordance with manufacturer recommendations. High Best grounding recommendations must be closely followed.
Medium to high Best grounding recommendations must be closely followed. Medium Determine source and cause of noise if possible, and mitigate as closely as possible at the noise source or reduce coupling from the noise source to the affected equipment. Low Electromagnetic noise problems are not anticipated, but installing a grounding system in a new building is often the least expensive route and the best way to plan for the future. Low Electromagnetic noise problems are not anticipated, but installing a grounding system is always recommended.
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. Preventing Electrostatic Discharge Damage Electrostatic discharge ESD damage, which can occur when modules or other devices are improperly handled, results in intermittent or complete failures. For preventing ESD damage, follow these guidelines: Always use an ESD wrist strap and ensure that it makes maximum contact with bare skin.
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. Step 2 Grasp the spring or alligator clip and momentarily touch the clip to a bare metal spot unpainted surface on the rack. Step 3 Attach the ESD strap to the system ground in one of the following ways: If you are using a wrist strap that is equipped with a plug, insert the plug into an open screw hole used for the grounding lug.
If you are using a wrist strap with spring or alligator clips, attach either the spring clip or the alligator clip to the ground lug screw: Figure 7. Note The spring clip jaws do not open wide enough to fit directly over the head of the lug screw or the lug barrel. In addition, follow these guidelines when handling modules: Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.
Caution For safety, periodically check the resistance value of the antistatic strap. You must observe the following system grounding guidelines for your chassis: You must install the NEBS ground connection with any other rack or system power ground connections that you make.
Required Tools and Equipment To connect the system ground, you need the following tools and materials: Grounding lug—A two-hole standard barrel lug. Grounding the Interconnect The chassis has a grounding pad with two threaded M4 holes for attaching a grounding lug. Statement Caution We recommend grounding the chassis, even if the rack is already grounded.
Caution All power supplies must be grounded. Figure 8. Statement Caution Grounding the chassis is required if you are using DC power supplies, even if the rack is already grounded. Procedure Step 1 Use a wire-stripping tool to remove approximately 0. 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.
Figure 9. Connecting the Cisco UCS UP System Ground 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.
Procedure 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 Cisco UCS Series Fabric Interconnect to your outlet receptacle. Step 3 Ensure that the chassis is adequately grounded, and that the AC or DC power available has the required power voltages see Power Specifications. Step 4 For a first-time installation, you will need to work with your network manager to determine the following parameters: System name Password for the admin account.
Step 6 If the fabric interconnect will be running in a cluster with another fabric interconnect, you will need to connect ethernet cables between the L1 and L2 ports.
Step 7 Connect the power cable to a power source. Step 8 Listen for the fans; they should begin operating when you plug in the power cable. Power supply—Status LED is green.
