NSS LEDs
You can use the NSS LEDs on the front of the NSS chassis to monitor NSS activity
and performance. The LEDs also help you troubleshoot a variety of conditions on
the NSS, from normal operating conditions, alerts, to serious error conditions.
Power Button LED
The Power Button LED shows whether the NSS is receiving power and is
functioning properly. These are the LED colors and their meanings:
• Solid Yellow: The NSS is powered on and the boot loader is currently
running. The boot loader runs for approximately 10 seconds when the NSS
first starts up, and then the LED blinks green.
This condition also occurs if the upgrade of the firmware process fails
(although in this case, the LED remains in a solid yellow condition until the
user clicks OK from the System Details page following an unsuccessful
upload. After the user clicks OK, the system reboots using the current
version of the firmware.
• Blinking Yellow: The network configuration factory defaults are being reset.
When resetting the network defaults, hold down the Reset button until you
see the Power LED flash yellow rapidly.
• Solid Green: The NSS is powered up and finished booting.
• Blinking Green: The NSS is either booting up or shutting down.
• Alternating Yellow & Green: The firmware update is currently in progress.
• Off: The NSS is either disconnected from a power source or has finished
the shutdown process and can be safely disconnected from a
power source.
