Table 13. NVRAM6 copper-fiber converter LED descriptions
Indicator Status Description
Green On Normal operation.
Green/Amber On Power is present but link is down.
Green Flickering or off Power is present but link is down.
Monitoring the power supply
The N7000 series system power supply has two LEDs. The LEDs indicate whether
the power supply is functioning normally or whether there are problems with the
hardware. You can also identify any hardware failure associated with the power
supplies from the error messages displayed on your system console.
A normal functioning power supply shows a green LED. A power supply fault
turns the LED to amber.
Location of LEDs
Each power supply is encased in a device carrier and housed at the rear of your
N7000 series system. Figure 9 on page 26 shows the location of the power supply
LEDs.
