Unit Load Calculation Worksheet

9.Try to exchange modules between carriers to reduce the unit loads for slots five and six through 27. (Remember that the 100D, 400, 400 GS/LS/TTR, 800 GS/LS-lD, 800, and 800 GS/LS modules have unit loads of 0.0, ) Repeat Steps 1 through 8 to recalculate unit loads for new configuration.

■If the exchange reduces the unit load for slots five and six through 27 or less, auxiliary power is sufficient.

■If the exchange does not reduce the unit loads for slots 5 and 6 through 27, install wall power units for the appropriate number of telephones to reduce the unit load to 27.

NOTE:

Empty slots are not permitted between modules.
