DS2000 System Load Factor Calculations
To check your DS2000 system configuration:
1.
Indicate the quantity for each item installed in the
Qty
column.
2.
For each item, multiply the
Qty
times the
Load Factor
and enter the value in the
Total Load
column.
3.
Add all the values in the
Total Load
column and enter the value in
Item 1
.
4.
Determine the System Load Factor capacity of the power supplies installed in your system
and enter the total in
Item
2
.
A 4-Slot Cabinet can have only 1 power supply. An 8-Slot Cabinet can have up to 3
power supplies. You cannot have more than two 16DSTU PCBs per power supply, regard-
less of System Load Factor calculations.
5.
Compare the entry in
Item
2
to your entry in
Item
1
. Item 1 must always be equal to or less
than the entry in Item 2.
Do not operate your system if the System Load Factor total (Item 1)
exceeds the allowable value (Item 2).
