4.4.3. Power Supply Unit Selection for Each Shelf
The Hybrid IP-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.

*1 Only the extension cards that can support SLTs count for the load figures.
PSU Capability
Each PSU supports a different load figure.
PSU Type Maximum Load Figure
PSU-M 128
PSU-L 512
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.
