System Preparation and Configuration
System Preparation and Configuration
Unpacking
Unpack the equipment and check it against your equipment lists. Inspect for physical damage. If you are not
sure about a component’s function, review the Product Description Manual. Contact your Sales Representa-
tive if you have additional questions.
Have the appropriate tools for the job on hand, including: a test set, a punch down tool and a digital voltmeter.
Before Installing
Make sure you have a building plan showing the location of the common equipment, extensions, the telco
demarcation and earth ground. In addition, the installation site must meet the requirements outlined in the
Standard Practices Manual.
Site Requirements
The common equipment is contained in the wall-mounted Main Equipment Cabinet. Choose a central location
for the cabinet that allows enough space for the equipment — and provides enough room for you to comfortably
work. Figure 1-1 4 Slot Cabinet Installation Layout on page 1-4 and Figure 1-2 8 Slot Cabinet Installation
Layout on page 1-5 show you about how much space your system requires.
System Configuration
Default Configuration
The factory installed default configuration for your DS2000 system (with software version 02.02.00 and
higher) is:
●
Slot CN1 = 16DSTU PCB (extensions 300-315).
●
Slot CN2-CN8 = Undefined.
●
Slots CN5-CN8 are only available with the 8 slot cabinet.
●
After plugging in your PCBs and powering up the system, use Program 9902 - Slot Control to enable
the installed PCBs. See Using Program 9902 in DS2000 to Add or Delete PCBs in your Quick Setup
Guide for more.

System Preparation and Configuration

DS2000 Configuration Guidelines
The total number of components you can install and connect depends on power supply capacity and the Sys-
tem Load Factor. Review the Configuration Guidelines table below and DS2000 Load Factor Calculations
on page 1-3 when configuring your system.
DS2000 Configuration Guidelines
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).
• You can install up to
40 extensions maximum, as follows:
(2) 16DSTU PCBs = 32 digital extensions
(1) 8ASTU PCB = 8 analog extensions
Total = 40 extensions
• You can install up to 24 trunks maximum, as follows:
(3) 8ASTU PCBs = 24 analog trunks
• Maximum configuration is 48 ports .
• The total of all extensions and trunks cannot exceed 48 .
• Always use the System Load Factor table to check your system configuration.

DS2000 Load Factor Calculations
The combination of extensions, Digital Door Boxes, 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 Cal-
culations chart to verify your system’s configuration.
To check your 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 inTotal Load.
3. Add all the values in theTotal 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.
5. Compare the entry in Item 2to your entry in Item 1. Item 1must 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 load (Item 2).

Item 2: If you have one power supply installed, enter 48.
If you have two power supplies installed, enter 80.
If you have three power supplies installed, enter 112.
Notes:
• A 4 slot cabinet can only have 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, regardless of System Load Factor calculations.
• Exceeding the System Load Factor will cause the system’s power supplies to automatically
shut down and/or erratic system operation.

Installing the Cabinet
1-4 ◆Section 1: Installing the Cabinet DS2000 Hardware Manual
Installing the Cabinet
Planning the Installation
Before installing the common equipment, you should mount a Main Distribution Frame (MDF) plywood back-
board in a centrally located spot. A 1/2 sheet of plywood (4’ x 4’) should be adequate for a 4 slot cabinet (see
Figure 1-1 4 Slot Cabinet Installation Layout below).A full sheet of plywood (8’x 4’) should be adequate for
an 8 slot cabinet (see Figure 1-2 8 Slot Cabinet Installation Layout on page 1-5 ). Be sure to mount the back-
board using suitable fasteners, taking care to adhere to standard installation practices and local codes.
The equipment cabinet requires a three-prong, dedicated 110 VAC 60 Hz circuit (NEMA 5-15 receptacle).
The AC receptacle must be within 7’feet of the cabinet’s lower left corner.
Normally, you install the extension and trunk blocks to the right of the cabinet. Telco should also install the
RJ21X to the right of the cabinet.
!! Important !!
• Local codes may prohibit you from installing extensions, trunks and optional equipment in
the same blocks.

Grounding the Cabinet
Removing the Right Side Panel
Remove the cabinet right side panel to gain easy access to the ground lugs and system cabling. The cabinet
has two ground connections: ETH (Earth Ground) and PBXG (PBX Ground).
To remove the right side panel (Figure 1-8):
1. Remove the two screws that secure the right side panel to the cabinet.
2. Carefully slide the right side panel down until it swings clear of the cabinet.
Attaching the Ground Wires
The system provides two ground terminations. Each ground connects from the system to the ground termina-
tion using 12 AWG stranded copper wire.
● Use the ETH (Earth Ground) for safety/system ground.You must connect ETH to a known earth ground.
● Use the PBXG (PBX Ground) if you have trunks that require telco ground (such as ground start trunks).
This ground is not required for loop start trunks.
Figure 1-8: Removing the Right Side Panel
!! Important !!
You must connect your system to a known earth ground according to the following
instructions.

RFI Suppressor Assemblies
Installing RFI Suppressor Assemblies
You must install RFI SuppressorAssemblies as follows (see Figure 1-10 Installing RFI Suppressor Assemblies
below). The suppressors must be mounted inside the cabinet and as close to the appropriate PCB as possible.
●For Station and Trunk Cables
– Only install these assemblies if you are installing non-A station and trunk PCBs in a 4 slot cabinet. If
you have a mixture of A and non-A PCBs, you only need to install the assemblies on the non-A PCBs.
– RFI assemblies on station and trunk cables are not required with 8 slot cabinets, since these cabinets
use only APCBs.
●For Ground Wires
–You must install a separate RFI assembly for the ground wire(s) in all systems.
– If your system has 2 ground wires, install them both in the same assembly.
●For CPU Connections
–You must install a separate RFI assembly for the CPU mod jack and RS-232 cables in all systems.
Install both cables in the same assembly.
