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 a HiPath 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 TS2N  
 
 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.
