4) Set the multimeter to the voltage scale.
5) Measure the voltage of the socket marked with SOCKET in the AC power
distribution box.
6) Check whether the voltage ranges from 90 V AC to 135V AC (110 V AC) or from
176 V AC to 264 V AC (220 V AC).
If yes, it indicates that the primary power supply works normally. Otherwise, the
primary power supply is faulty. In this case, you must look for fault causes
carefully.

6.2.2 Power-on Check of Power Modules

Proceed as follows to conduct the power-on check of the power modules:
1) Disassemble the AC input power box to check that the AC three-phase cables are
correctly connected.
2) Power on the AC power distribution box.
3) Check the voltages of the three-phase cables and the phase voltages.
4) Check that all the PSUs are well-connected with the motherboard.
5) Switch on the primary power supply to check that indicators of power modules are
normal.
In the normal case,
6) Set the multimeter to the voltage scale. Measure the output voltage at the voltage
test port on the AC power distribution box of the main equipment to check that it is
normal and within the range of 19 V to 29 V.
7) Switch off the primary power supply if the voltage is unstable or beyond the range.
8) Clear the fault and power on again until the voltage is normal.

6.2.3 Power-on Check of Air Conditioner

Proceed as follows to conduct the power-on check of the air conditioner:
1) Switch off the BAT switch on the AC power distribution box.
