  If you're experiencing a power supply system failure with your HP Switch, begin by checking the power cable connections and re-plug any loose cables. If the issue persists, try replacing the power cable and observe the LEDs. Ensure the power supply is fully seated; if not, reinstall it. Verify that the power source is working correctly and providing the correct voltage. Also, check for any output short circuit, over-current, over-voltage, input under-voltage, or over-temperature problems. Try plugging the power supply into an empty slot to see if the slot is the issue. Finally, test with a known good power supply in the same slot to determine if the original power supply has failed and needs replacement.

How to troubleshoot an interface failure on my HP 12500 Switch?

  If your HP Switch interface is failing, start by verifying that the MPU or LPU where the interface is located is functioning correctly. Check the cable connection and ensure the cable isn't broken by testing it with a known good interface. If using a transceiver module, confirm compatibility between the interface type, transceiver module, and cable. Try replacing the transceiver module with one that is known to be working. Use the 'display interface' command to ensure the interface is UP; if not, use the 'undo shutdown' command. Also, confirm that the speed and duplex settings are the same on both ends of the connection.

  To troubleshoot an MPU failure in your HP Switch, first, make sure the power supply is working correctly. Then, press the RESET button on the MPU and check that the RUN LED flashes green after the reset. Verify that the MPU is fully seated in its slot. If possible, try plugging the MPU into an empty slot to see if it operates correctly there.

  To resolve a fan failure in your HP Switch, first, check that the power supply is working properly. Ensure that the air intake and exhaust vents are not blocked; if they are, clean them. Make sure the fan tray is fully seated by unplugging it and plugging it back in, then check the fan LEDs. If you have a spare fan tray, try using it to see if the old one is faulty.

  Ashley BassAug 25, 2025
  To address a switching fabric module failure in your HP Switch, first verify that the MPU is operating correctly. Use the display device command to check if the software version is compatible with the switching fabric module in the current slot; if not, upgrade the software. Calculate the overall power consumption to ensure your power supply provides sufficient power. Ensure that the switching fabric module is fully seated by unplugging and re-plugging it. If there are empty slots, test the module in an empty slot.

Why is there no terminal display on my HP 12500 Switch?
- E
  Elizabeth GeorgeAug 28, 2025
  If you have no terminal display when connecting to your HP Switch, verify that the console cable is connected to the correct serial port and that the power supply system and main processing unit (MPU) are operating properly. Ensure the console cable is connected to the console port of the MPU. Also, ensure that the terminal properties are correctly configured: Bits per second should be set to 9600, Data bits to 8, Parity to None, Stop bits to 1, Flow control to None, and Terminal Emulation to VT100. If the issue persists, try replacing the console cable.
