Chapter4 Installing a Cisco Nexus Fabric Extender
Removing and Installing Components
To install a power supply, follow these steps:
Step1 Ensure that the system (earth) ground connection has been made for the chassis. For ground connection
instructions, see the “Grounding the System” section on page4-7.
Step2 If the power supply bay has a filler panel, remove it from the slot as follows:
•If you are removing a filler panel from a Cisco Nexus 2248TP, 2232PP, or 2224TP FEX, push its
thumb latch to the left and pull the panel out of the chassis.
•If you are removing a filler panel from a Cisco Nexus 2148T FEX, loosen its captive screw, and then
pull the panel out of the power supply bay.
Step3 Hold the replacement power supply by its handle and position it so that the captive screw is on the left,
and then slide it into the power supply bay, ensuring that the power supply is fully seated in the bay.
Step4 Secure the power supply to the chassis as follows:
•If you are installing a Cisco Nexus 2248TP, 2232PP, or 2224TP FEX, make sure that the thumb latch
engages with the chassis so that the power supply is held in the slot.
•If you are installing a Cisco Nexus 2148T, fasten the power supply to the chassis by screwing its
captive screw into its hole in the chassis and tightening it.
Note Depending on the outlet receptacle on your power distribution unit, you may need the optional
jumper power cord to connect the Cisco Nexus 2000 Series FEX to your outlet receptacle. See
the “Jumper Power Cord” section on pageC-8.
Step5 Connect the other end of the power cable to an AC power source.
Caution In a system with dual power supplies, connect each power supply to a separate power source.
If a power source failure occurs, the second source will most likely still be available.
Step6 Verify power supply operation by checking that the power supply LED is green. For information about
what the power supply LEDs indicate, see the “Power Supply Status” section on pageE-3.
Removing a DC Power Supply
Caution If you are using the Cisco Nexus 2200 platform FEX with one DC power supply, removing the power
supply causes the device to shut down. If you are using two power supplies and you remove one of them,
the device continues to operate.
To remove a DC power supply, follow these steps:
Step1 Shut off the DC power to the power supply at the circuit breaker. Make sure that both LEDs are off.
Step2 Unfasten the positive power cable from the negative (-) terminal.
Step3 Unfasten the negative power cable from the positive (+) terminal.
Step4 Press the thumb latch to disengage the power supply from the chassis and use the handle to pull it part
way out of the chassis.
