Step7 After the device boots, verify that the LED operation is as follows:
•Power supply—The system 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 monitor is reporting a problem.
•The Link LEDs for the Ethernet connector should not be on unless the cable is connected.
If a component is not operating correctly, remove and reinstall that component. If it still does not operate
correctly, contact your customer service representative for a replacement.

Caution To prevent ESD damage, wear grounding wrist straps during these procedures and handle modules by

Removing and Installing Power Supplies

The Cisco Nexus 2000 Series FEX supports two power supplies, but the FEX uses only one power supply
for operations. The other power supply is for redundancy.
Caution Whenever you replace a power supply, make sure that it has the same direction of airflow as the rest of
the module in the switch (all fan tray and power supply modules must have the same direction of airflow
and the same color designation for the airflow direction or else the switch can over heat and shut down.
