Why is there no display on my HPE OfficeConnect 1950?
If there is no display on your HPE Switch, verify the following: * The power system is operating correctly. * The switch is operating correctly. * The console cable has been connected correctly. * The terminal settings are configured as follows: Baud rate—38400, Data bits—8, Parity—None, Stop bits—1, Flow control—None. * The console cable is not faulty.
What to do if HPE Switch AC input fails?
If the AC input fails on your HPE Switch, check these items: * Make sure the AC power cord is securely connected to both the switch and the AC power outlet, and that both the receptacle on the switch and the outlet are in good condition. * Confirm that the AC power source is working correctly. * Ensure the switch's operating temperature is within the acceptable range and that the power supply has good ventilation. Over-temperature conditions can cause the power supply to stop working as a protective measure.
What to do if HPE OfficeConnect 1950 RPS DC input fails?
If the RPS DC input fails on your HPE Switch, check the following: * Ensure the switch is securely connected to the RPS. * Verify that the RPS is operating correctly. * Confirm that the operating temperature of the switch is within the acceptable range, and the power supply has good ventilation. Over-temperature can cause the power supply to stop working and enter the protection state.
What to do if HPE Switch experiences both RPS and AC input failure?
If your HPE Switch experiences concurrent RPS and AC input failure, verify the following: * Ensure the AC power cord is securely connected to the switch, and the AC-input power receptacle on the switch and the connected AC power outlet are in good condition. * Verify that the AC power source is operating correctly. * Confirm that the switch is securely connected to the RPS. * Check that the RPS is operating correctly. * Ensure that the operating temperature of the switch is within the acceptable range, and the power supply has good ventilation. Over-temperature can cause the power supply to stop working and enter the protection state.
How to fix garbled display on HPE OfficeConnect 1950 Switch?
To fix a garbled display on your HPE Switch, ensure the following terminal settings are configured correctly: * Baud rate—38400 * Data bits—8 * Parity—None * Stop bits—1 * Flow control—None
