For upgrade with additional drives add the following figures per drive:

                                    AC RMS current*
                 BTU   Watt   VA   @200VAC  @240VAC
                -----  ----  ----  -------  -------   
9GB/7200rpm:    77.8   22.8  25.33  0.127    0.106
18GB/7200rpm:   97.6   28.6  31.80  0.159    0.132
9GB/10Krpm:     69.4   20.3  22.60  0.113    0.094

*  The AC RMS current is the calculated rack AC input current assuming only
   one power sequencer is operational. Calculation is based on 0.9 power
   factor, 70% power supply efficiency on the A3000 and D1000 power supplies. 
** The 3x15 configuration consists of two racks: a 2x7 rack and a 1x8 rack.
   For the 2x7 rack power data refer to the 2x7 max configuration.  


3.  StorEdge A3000 and StorEdge A3500 cold start initial surge current 
    specification:

   Tray level initial surge current specification:
   -----------------------------------------------

   RSM disk tray, each power supply: 
     15 A rms or 21 A peak for one line cycle.

   StorEdge A3000 controller module, each power supply:
     25 A rms or 35 A peak for one line cycle.
 
   StorEdge D1000 disk tray, each power supply: 
     11 A rms or 22 A peak for one line cycle.

   Rack level initial surge current specification:
   -----------------------------------------------

   StorEdge A3000 (StorEdge A3000 controller with RSM disk tray in 56" rack)

    1x5 configuration, per power cord: 120 A rms for one line cycle or 169 A peak.

   StorEdge A3500 (StorEdge A3000 controller with D1000 disk tray in 72" rack)

    1x2 configuration*, per power cord: 47 A rms for one line cycle or 79 A peak.
    
    1x5 configuration, per power cord: 44 A rms for one line cycle or 88 A peak.
     
    2x7 configuration, per power cord: 72 A rms for one line cycle or 114 A peak.
 
    1x8 configuration, per power cord: 55 A rms for one line cycle or 110 A peak. 

* Assume the rack contains only one 1x2 configuration. The A3000 controller and
  the two D1000 trays are powered off from one sequenced output.
