Power supply
Configuration
Choosing system power solution:
- Solution 1: PWS 323005 will be chosen as system power supply inside riser while
auxiliary PWS (323010) will be chosen for all the assistant power supply.
- Solution 2: PWS 323005 will be chosen for both system power supply inside riser and
assistant power supply.
Note: when the system has Small EP, solution 2 will be helpful to avoid possible damage
to the power supply in the system. When the system has IU connected with Small EP, at
some occasions, if several Small EPs call IU at the same time, it will make power supply
overloaded.
Under this situation, the power supply is at risk to be damaged.
