Identifying the Primary System Power Requirement 
 

Procedure  
Proceed as follows to identify the primary power requirement of a system:
 1.   Determine overall secondary power requirement
   
 
power requirements of the boards/components used  
+  
power requirement of connected workpoint clients (analog and digital telephones), key modules and adapters  
=  
overall secondary power requirement  
 2.   Identifying primary power requirement
   
 
overall secondary power requirement  
+  
requirements of power supply units (LUNA2 = 9 W, PSUP/UPSC-D/UPSC-DR = 12 W respectively)  
+  
requirements of Powerbox PB3000 with LUNA2 (9 W)  
=  
the result should be multiplied by the factor 1.3 to allow for the degree of efficiency of the power supply.  
   

Sample calculation for aHiPath 3550  
 1.   Determine overall secondary power requirement
   
 
power requirements of the boards/components used =  
 7.50 W
 
1 x CBCC  
 
 12.80 W
 
1 x HXGS3 (including ventilator kit)  
 
 0.90 W
 
1 x TS2  
 
 2.40 W
 
3 x SLU8  
 
 2.60 W
 
1 x 8SLA  
 
 5.00 W
 
1 x SLC16N  
 
 24.00 W
 
12 x BS3/1  
+  
power requirement of connected workpoint clients, key modules and adapters =  
 4.32 W
 
6 x optiPoint 500 advance  
 
 8.40 W
 
12 x optiPoint 500 basic  
 
 2.40 W
 
8 x optiPoint 500 entry  
 
 0.00 W
 
2 x Hicom Attendant BLF  
 
 0.00 W
 
2 x optiPoint BLF  
 
 0.40 W
 
8 x optiPoint key module  
 
 0.50 W
 
2 x optiPoint acoustic adapter  
 
 1.80 W
 
6 x analog workpoint clients  
=  
overall secondary power requirement =  
 74.43 W
 
 
 2.   Identifying primary power requirement
   
 
overall secondary power requirement =  
 74.43 W
 
 
+  
UPSC-D requirement =  
 12.00 W
 
 
Allow for the degree of efficiency of the power supply unit:  
 86.43 W
 
x 1.3 = 112.4 W  
    The primary power requirement of HiPath 3550 with the expansion mentioned amounts to approximately 112.4 W.
