F5 LTM Stuck in AOM Mode - Has anyone ran into this?

We were able to login into the AOM Command Menu with the CTRL+ESC+9
combination.

Will you explain why both of these units, in high availability, are going into
AOM rather than the standard login?

Also when trying to power on the subsystem, we receive a " Powering on host
subsystem.... . . . . . . . . . failed!".

Please see below and reply all so the team here can work and respond to this
problem 24/7.

I suggest you contact F5 support first for a quick recovery if you have SLA.

I have connected a PC via the console port and then powered on so you can see all power-up messages?

Re-looking at the messages it looks like a power problem.  I'm surprised the F5 has not just RMA'ed the units.

Did you happen to have some power problems recently?  Do these units have dual power supplies?  Do you ahve them on a protected circuit or connected to a good and heathy UPS.

The below seems to indicate that PS1 is bad or not plugged in.  No input voltage and the fan is not on.  Not sure what the ACOK  means, GPIO is General Purpose Input/Output.  I am assuming that AOM is using the GPIO interface on the power supply to see what is going on in the power supply.

I'm not sure what ZPOL1 is, but F5 support should.

Sensors out of range:
+3.3V ZPOL1 Voltage                        : Faulted!
PS1: Meas. AC input voltage (mV)           : 0 mV
PS1: Meas. fan speed (RPM)                 : 0 RPM
PS1: Meas. ACOK GPIO                       : 0x0000
PS2: Meas. ACOK GPIO                       : 0x0000

Then we have another fault and again I'm not sure what ZPOL13 is.

Sensors out of range:
+1.5V_VTT1 ZPOL13 Voltage                  : Faulted!
PS1: Meas. ACOK GPIO                       : 0x0000
PS2: Meas. ACOK GPIO                       : 0x0000

My guess is that ZPOL1 and ZPOL13 are names of signals that are being checked and they are not returning the expected value.   I would further assume that ZPOL1 should be returning 3.3 volts and ZPOL13 should be returning 1.5volts and both may be returning none at all.

trying to work with another engineer over there. I think you a right.

F5 did find it to be a hardware issue. Not being in the state, we were hoping that was not the case. Nonetheless, we should have a new new 10000 unit on the way. Thanks!
