IPMI power on Lambda Vector system not working

We have 3 Lambda Vector systems that ended up in a remote data center. I can access them via IPMI, but I’m unable to power them on.


$ ipmitool -H $IPADDRESS -U admin shell
Password:
ipmitool> chassis status
System Power : off
Power Overload : false
Power Interlock : inactive
Main Power Fault : false
Power Control Fault : false
Power Restore Policy : always-off
Last Power Event : command
Chassis Intrusion : inactive
Front-Panel Lockout : inactive
Drive Fault : false
Cooling/Fan Fault : false
Sleep Button Disable : allowed
Diag Button Disable : allowed
Reset Button Disable : allowed
Power Button Disable : allowed
Sleep Button Disabled: false
Diag Button Disabled : false
Reset Button Disabled: false
Power Button Disabled: false


ipmitool> chassis power on
Chassis Power Control: Up/On

I also tried ‘up’:

ipmitool> chassis power up
Chassis Power Control: Up/On


ipmitool> chassis status
System Power : off
Power Overload : false
Power Interlock : inactive
Main Power Fault : false
Power Control Fault : false
Power Restore Policy : always-off
Last Power Event : command
Chassis Intrusion : inactive
Front-Panel Lockout : inactive
Drive Fault : false
Cooling/Fan Fault : false
Sleep Button Disable : allowed
Diag Button Disable : allowed
Reset Button Disable : allowed
Power Button Disable : allowed
Sleep Button Disabled: false
Diag Button Disabled : false
Reset Button Disabled: false
Power Button Disabled: false


Neither option powered on the system. When I tried with capitalized On/Up as per the output, that’s apparently not valid:


ipmitool> power On
Invalid chassis power command: On
ipmitool> power Up
Invalid chassis power command: Up


The motherboard is an ASUS Pro WS WRX80E-SAGE SE. I checked their Manual and Getting started guide, but I didn’t find any solutions.

Unfortunately I don’t have physical access to poke around the BIOS of the system. Does anyone have any ideas why I can’t remotely power it on, or how to enable remote power on?

Thanks!
