DSX-80/160 System Load Factor
The combination of lines and extensions you can connect to your DSX system may be limited by the System
Load Factor. Use the DSX-80/160 System Load Factor Worksheet on the next page to verify your system’s
configuration. When entering data on the worksheet, for each installed card 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 card installed in the Qty column.
- The number of keysets, single line sets, and DSS Consoles does not affect the load factor.
2.
For each item and for each Load Type, multiply the
Qty
times the
Load
and enter the value in the
Total
column.
- For example, two 16ESIU Cards have a load of 16 for 5 VDC and 40 for 40 VDC.
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.
Important
Do not operate your system if the total for either Load Type
exceeds the Power Supply Capacity of your installation.
