Troubleshooting and error codes

Status	Meaning
Green	The unit is powered on and ready for use.
Yellow	Power-on self-test or loop back test failed. The switch is in fail-safe mode. This can happen if a port or ports fail when the switch was powered on.
OFF	The unit is not receiving power. Verify that the power cord is connected correctly, and then try powering on the switch again. If the switch still does not operate, contact your HP network supplier.
