Chapter 4 Installing a Cisco Nexus Fabric Extender
Removing and Installing Components
Note If you remove a fan tray while the system is running, you must install the new fan tray within 1
minute to prevent overheating.
Installing a Fan Tray
To install a fan tray, follow these steps:
Step 1 Hold the fan tray with the sheet metal flange holding the connector on the bottom.
Step 2 Place the fan tray into the port-side exhaust chassis cavity so it rests on the chassis, and then push the
fan tray into the chassis as far as it can go until the captive screw makes contact with the chassis.
Step 3 Tighten the captive screw.
Step 4 Listen for the fans if the device is powered on. You should immediately hear them operating. If you do
not hear them, ensure that the fan tray is inserted completely in the chassis and the faceplate is flush with
the outside surface of the chassis.
Step 5 Verify that the LED is green. If the LED is not green, one or more fans are faulty. If this problem occurs,
contact your customer service representative for a replacement part.

Removing the Cisco Nexus Fabric Extender
Caution The slider rail and port side exhaust rack-mount brackets do not have a stop mechanism when sliding in
and out. If the port side exhaust 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.
To remove the Cisco Nexus 2000 Series FEX from a rack, follow these steps:
Step 1 Ensure that the weight of the FEX is fully supported and that the device is being held by another person.
Step 2 Turn off the power at the circuit breaker.
Step 3 Disconnect the power cord as follows:
• For AC power supplies, disconnect the power cord and the console cables.
• For DC power supplies, disconnect the positive cable from the negative (-) terminal, and disconnect
the negative cable from the positive (+) terminal.
Step 4 Disconnect all ports.
Step 5 Remove the screws that fasten the port side exhaust rack-mount brackets to the mounting rails.
