Prerequisites
The system is powered on, commissioned, and working properly.
Devices that have two power supplies have been properly powered on by both supplies.
This section describes how to switch between the two power supplies to the ECC800.
Procedure
Step 1
Switch off the rPDU input circuit breaker that controls one power supply to the ECC800.
Step 2
Power on the ECC800 after 30 seconds, and check that the ECC800 works properly.
Step 3
Switch off the rPDU input circuit breaker that controls the other power supply to the ECC800.
Step 4
Power on the ECC800 after 30 seconds, and check that the ECC800 works properly.
If the ECC800 works properly during the process and does not restart or break down, the two power
supplies are switched over normally.
