DS2000 Load Factor Calculations

The combination of trunks, extensions, 2-OPX Modules and DSS Consoles you can connect to your DS2000
system may be limited by the System Load Factor. Use the DS2000 System Load Factor Calculations chart
on the next page to verify your system's configuration. When entering data on the chart, for each installed
item make entries for each Load Type. There are two Load Types to consider: 5 VDC and 40 VDC.
To check your system configuration:
1. Indicate the quantity for each PCB, DSS Console, and 2-OPX Module installed in the Qty column.
2. For each item for each Load Type, multiply the Qty times the Load and enter the value in the Total
column.
3. Add up the entries in each Total column and enter the values in Item 1: Load Type Totals .
4. Review Item 2: Power Supply Capacity and determine the capacity of the power supplies installed
in your system.
5. Compare the capacities in Item 2 to your entries in Item 1 . Item 1 must always be equal to or less than
the entry in Item 2 .
1-6 N Section 1: Installing the Cabinet
The number of keysets and single line sets does not affect the System Load Factor.
For example, two 16DSTU PCBs have a load of 6 for 5 VDC and 40 for 40 VDC.
Do not operate your system if the total for either Load Type
exceeds the Power Supply Capacity of your installation.
