DS2000 Load Factor Calculations

22 N Section 2: Components
Automatic Slot Configuration automatically sets up your system's PCBs when you initially power
up the system. There is no longer a factory-installed default configuration, and you don't have to
use system programming to activate PCBs after you plug them in. Remember, you should always
plug a 16DSTU PCB into slot CN1.
The total number of components you can install and connect depends on power supply capacity and
the System Load Factor. Review the DS2000 Configuration Guidelines table and DS2000 Load
Factor Calculations below when configuring your system.
4 Slot Cabinets
• Do not install more than 2 16DSTU PCBs under any circumstances.
• The first 16DDSTU PCB you install must be in the first slot (CN1).
• Maximum configuration is 64 ports .
• The total of all extensions and trunks cannot exceed 64 .
• Always use the System Load Factor table to check your system configuration.
8 Slot Cabinets
• Do not install more than 2 16DSTU PCBs for each power supply. (Install your power sup-
plies in the following order: slot CN101, slot CN103, slot CN102.)
• The first 16DSTU PCB you install must be in the first slot (CN1).
• The total of all extensions and trunks installed cannot exceed 112 .
• Maximum configuration is 112 ports.
• Always use the System Load Factor table to check your system configuration.
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 Fac-
tor 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.
The number of keysets and single line sets does not affect the System Load Factor.
2. For each item for each Load Type, multiply the Qty times the Load and enter the value in the
Total column.
For example, two 16DSTU PCBs have a load of 6 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 .
Do not operate your system if the total for either Load Type
exceeds the Power Supply Capacity of your installation.
