Power Supply Unit Selection for Each Shelf
The PBX needs a power supply unit (PSU) suitable for its configuration. For each shelf, calculate the load
figure from the type and number of items of equipment to be connected, and then determine the type of PSU
that will be required.
Note
Regardless of the total load figure, if a shelf contains an ECSLC24 card, the PSU-L must be installed.
