SECTION 2-3
Blade Load Factors
In addition to the blade capacities listed on the previous pages, you must take into consideration the power
load factors for certain blades as well as station equipment (such as terminals, terminal adapters, and
consoles).
The maximum load factor for blades per system chassis (either 9.5” Chassis-B/E or 19” Chassis-A) is 7. The
maximum load factor for station equipment is either 64 (for 9.5” Chassis-B/E) or 80 (for 19: Chassis-A).
Refer to the following charts to determine the load factor for your equipment. Any blades or devices not
listed in these charts should not require consideration when determining the load factor (such as the
MEMDB or voice mail daughter board). Keep in mind that each 19” chassis (either 2 9.5” chassis combined
or 1 19” chassis) has a maximum number of timeslots for audio of 104. This means that any blade
combination within one system chassis cannot exceed 104 station or trunk ports.
✎ Make additional copies of these pages for each chassis to be configured.

The Station Equipment Load Factor must also be considered.
