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.
Load Figure Calculation
*1 the extension cards that can support SLTs count for the load figures.
PSU Capacity
Each PSU supports a different load figure.
If the total load figure is greater than 128, you must install the PSU-L. If the total load figure is less than 128, but you expect
expansion in the future, it may be better to install the PSU-L instead of the PSU-M. There is no harm in installing a PSU that is
larger than is required for the current configuration.
