Chapter 2 Installing the Cisco Nexus 3000 Series Switches
Starting the Switch
e. Connect a positive cable from the power source to the right terminal (is labeled + on newer power
supplies [see Callout 2 in Figure 2-8] and - on the first power supplies sold[see Callout 4 in
Figure 2-8]) on the power supply and fasten with the screw for that terminal.
f. Clip on the clear plastic safety cover over the terminals to prevent accidental touching of these
terminals.
g. Turn on the power at the circuit breaker.
h. Verify that the power supply is functioning by making sure that the OK LED turns green and the
FAULT LE D is off.
Step 6 Connect each power cable to the AC or DC power source. Press the power cable into the power clip to
ensure that the power cable stays connected to the chassis when bumped. The switch should power on
as soon as you connect the power cable.
Step 7 Listen for the fans; they should begin operating when the power cable is plugged in.
Step 8 After the switch boots, verify that the LED operation is as follows:
• Power supply—Status LED is green.
• Fan module—Status LED is green.
• 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, one or more
environmental monitors is reporting a problem.
• The Link LEDs for the Ethernet connector should not be on unless the cable is connected.
Step 9 If a fan tray or power supply is not operating correctly, try removing it and reinstalling it (see Chapter 4,
“Replacing Components”). If it still does not operate correctly, contact your customer service
representative for a replacement.

Step 10 Verify that the system software has booted and the switch has initialized without error messages.
Step 11 Complete the worksheets provided in Appendix E, “Site Planning and Maintenance Records,” for future
reference.
Note A setup utility automatically launches the first time 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 Nexus 3000 Series CLI configuration guide.
