After connecting the power cable to the RH2285 V2 server, the power indicator is always in "blinking yellow" state and never power-on.
iMana interface indicator blinks but iMana is not accessible.
1. Check if the power supply unit (PSU) is properly installed but not powered on, power on the PSU. Then the RH2285 V2 is powered on together with the PSU.
2. Check if the PSU is powered on and the RH2285 V2 works in standby mode, power on the RH2285 V2 by using the power switch on the front panel.
3. Try to replace the mainboard with a good one and check if the server can be powered on and managed via iMana.
After the mainboard replacement, server can start and managed via iMana.
