RMA process power supply MHO-175

Wolfgang — Tue, 29 Apr 2025 12:11:36 GMT

Recently we had a RMA of a faulty Power Supply in a MHO-175. TAC sent us a complete MHO-175 and suggests to change the whole appliance. We had a longer discussion with TAC because we didn't want to change the whole MHO. But we should do.

We changed all cabling, removed the MHO from rack, replaced the MHO and did a restore from backup. That's a lot of work to do and should be easier. Normally we had to remove the faulty power supply and install the new one. It's done in a minute, no restore, no cabling changes etc.

Is this a new way TAC did, why do they not sent a new power supply only if it's faulty ?

According to AI copilot, appears what you believe should be possible.

This is Check Point AI Assistant.

Here’s a step-by-step guide for the RMA (Return Material Authorization) process for a power supply unit (PSU) in the MHO-175 Quantum Maestro Orchestrator:

1. Identify the Faulty Power Supply

The MHO-175 has two power supply units for redundancy.
Each PSU has a status LED. If the LED is not steady green, the PSU may be faulty.
You can check the PSU status on the rear panel:

2. Before Removing the PSU

Important: Make sure the System Status LED is steady green and the remaining PSU’s LED is also steady green.
The MHO-175 can operate with only one PSU, but do not leave a PSU slot empty for more than five minutes to ensure proper cooling.
Safety Note: With the fan unit or PSU removed, power pins are accessible. Do not insert tools or body parts into the cavity.

3. Remove the Faulty PSU

Disconnect the power cable from the PSU.
Release the latch and gently pull the PSU out of the chassis.
Do not leave the slot empty for more than five minutes.

4. Contact Check Point Support for RMA

Open a support ticket at Check Point Support Center.
Provide the following information:
- Appliance model (MHO-175)
- Serial number
- Description of the issue (including LED status)
- Steps already taken (e.g., swapped power cables, checked LEDs)
- Photos of the PSU and LED status (if possible)

5. Install the Replacement PSU

When you receive the replacement PSU, insert it into the empty slot.
Secure it and reconnect the power cable.
Verify the PSU status LED is steady green.

6. Return the Faulty PSU

Follow the instructions provided by Check Point for returning the faulty unit.

Additional Notes

Airflow Direction: Ensure the airflow direction of the PSU matches the fan modules for proper cooling.
Do not mix airflow directions in the same rack.

For more details, refer to the Quantum Maestro Getting Started Guide or open a ticket with Check Point Support if you need further assistance.

The 175 comes with 2 power supplies standard. Also you can order a extra power supply

AC power supply unit replacement for MHO 140 and 175, with front to back airflow: CPAC-PSU-AC-MHO140/175

So I see no reason why you could just swap the supply itself.

@Lesley that's what I thought, but TAC insisted on changing the whole device.

In theory you are the owner of the appliance so if you really want you can do what you want 😉

Maybe there is a reason that why RMA team did it this why, no idea why. We have not this info.

You always could just swap the power supply and tell in the case it works and hope they accept. (because if they send new unit they want the old one back + they to S/N swap in administration.)
