(for lithium batteries).

check whether the PWR indicator on the smart module actuator lights up.
Step 4 Switch on the smart cooling product circuit breakers in the integrated UPS to
power on the smart cooling products.

the rPDUs in the network cabinet and IT cabinets to power on the equipment in
the network cabinet and IT cabinets.
● Do not switch on the reserved circuit breakers.
● When switching on the circuit breakers, observe whether there is any abnormal
phenomenon, such as sparks or unsmooth switching.
