If your HP Switch has no power, check the power cord at both ends to ensure it is securely plugged into the switch and a working power outlet. Try power cycling the switch by unplugging it and plugging it back in. Also, try plugging another device into the same outlet or using a different power cord to verify the power source.
What to do if there is no link on HP Switch port?
If there's no link on a port of your HP Switch, first, verify that both ends of the network cable are securely connected to the switch and the connected device. Second, check that both the connected device and the switch are powered on and functioning correctly. Finally, for 1000 Mbps connections, make sure the network cable meets the IEEE 802.3ab standard.
Why is the port security disabling the port on my HP Switch?
If the link LED is flashing on your HP Switch, it means the network port has been disabled due to a security violation detected by the port security feature. The switch can be configured to disable a port whenever a security violation is detected.
What to do if the fan fails on HP Switch?
If a fan fails on your HP Switch, try disconnecting the power, waiting a few moments, and then reconnecting it to see if the error clears. If the fan failure indication persists, it could mean one or more fans have failed. Ensure the ambient temperature is within normal room temperature.
What to do if power supply fails on HP Switch?
If the power supply fails on your HP Switch, first, verify that the power cord for the power supply is securely plugged into both the switch and a working power source. If it doesn't help, disconnect the AC power cord from the power supply, then try removing and reinstalling the power supply. Reconnect the power supply to the AC power source. If the error persists, the power supply may be faulty.
What to do if module self test fails on HP Switch?
If a module self-test fails on your HP Switch, try removing and reinstalling the module. If the fault indication continues, the module may be faulty. Remove the module and replace it with another one, or install a slot cover plate.
What to do if module-based port self test fails on HP Switch?
If a module-based port self-test fails on your HP Switch, try removing and reinstalling the module. If the port is a mini-GBIC, you can remove and reinstall the mini-GBIC without removing the entire module. If the port fault indication reoccurs, replace the mini-GBIC or the module.
What to do if fixed port self test fails on HP Switch?
To verify if a fixed port has failed on your HP Switch, try power-cycling the switch. If the port fault indication reoccurs, you will need to replace the switch.
What to do if self test fails on entire HP Switch?
