Reserve Power Option
Strata DK I&M 5/993-17
DK40i Installation
Reserve Power Option
A reserve power source (two customer supplied 12-volt batteries) can be connected to the DK40i 
power supply to ensure uninterrupted system operation in the event of a power failure. A pre-
assembled interface cable for installation of the Reserve Power option is available from Toshiba 
(PBTC-3M), see Figure 3-12.
Figure 3-12 System Power Supply Wiring
Important!Local ordinances may dictate battery type and installation details.
The batteries require a well-ventilated location within nine feet of the system (the interface cable is 
nine feet long).
WARNING! To reduce the risk of fire or injury to persons, read and follow these instructions:
äUse only 12-volt, gelcell batteries.
äDo not dispose of the batteries in a fire. The cells may explode. Check with local 
codes for possible special disposal instructions.
äDo not open or mutilate the batteries. Released electrolyte is corrosive and may 
cause damage to the eyes or skin. It may be toxic if swallowed.
äExercise care in handling batteries in order not to short the battery with 
conduction materials such as rings, bracelets, and keys. The battery or 
conductor may overheat and cause burns.
äCharge the batteries provided with or identified for use with this product only in 
accordance with the instructions and limitations specified in this manual.
äObserve proper polarity orientation between the batteries and battery charger.

Reserve Power Installation 
1. Connect the PBTC-3M black jumper wire from the positive terminal of one 12VDC battery to 
the negative terminal of the second 12VDC battery. See Figure 3-12.
2. Ensure that a serviceable 10-ampere fuse is installed in the in-line fuse holder of the PBTC-
3M battery cable.
3. Connect the white lead of the PBTC-3M battery cable to the open positive terminal of the 
12VDC battery. Connect the black lead to the open negative terminal of the second 12VDC 
battery.
Important!The KSU must be connected to the live operating (hot) AC power source, and the 
power supply ON/OFF switch set to ON prior to the final step of connecting the 
reserve power batteries to the power supply via the BATT +/- receptacle. If the 
batteries are connected after AC power is lost, reserve power will not function.
4. Connect the PBTC-3M battery cable two-prong male plug to the power supply BATT +/- 
receptacle.
5. To test reserve power operation, disconnect the system AC power plug with the power supply 
power ON/OFF switch in the ON position. The system should continue to operate without any 
interruption.
6. Plug the AC power cable into PN2. 
7. Plug the AC power cable into an outlet and turn ON the power supply switch.
8.See “Prior to Installation” to confirm that the power supply is working properly.
9. Plug reserve battery cable into BATT connector of power supply.
Power Failure Emergency Transfer Option
To enable this option, a dedicated standard telephone must be connected to the Power Failure 
Transfer Interface (PF1) of a DK40i Base KSU equipped with a TCOU.
NoteDuring normal operation, this telephone cannot be used and does not count as a station 
(does not reduce the number of system’s available stations).
If there is a power failure, the telephone automatically is connected to CO Line 1. When power is 
restored, the system resumes normal station and CO line assignments, and the dedicated telephone 
becomes inoperative again.
Important!This is not available on a DK40i system with a TDDU installed.
Installing Power Failure Emergency Transfer
äConnect a standard telephone to the PF1 connector in the Base KSU (see Figure 3-13).
Testing Power Failure Emergency Transfer
1. Turn the system power switch OFF.
2. Lift the emergency standard telephone handset, and verify that there is CO dial tone.

Power Supply Removal and Replacement
The power supply (TPSU16A) comes factory-installed in the Base KSU; if necessary, it can be 
removed and replaced.
Power Supply Removal
1. Make sure that the power supply switch is OFF and that the AC power cable is not plugged 
into an outlet. Confirm that the green AC LED is not lit (see Figure 3-14).

DK40i Installation
Printed Circuit Board (PCB) Installation
This section details Strata DK40i system PCBs installation into the Base and Expansion KSUs. 
Also described are optional configuration information and programming considerations for each 
PCB.
Base KSU PCBs
The Strata DK40i processor is built into the motherboard (TMAU2) and comes with eight digital 
telephone circuits (ports). The line circuits are on the TCOU or TDDU PCBs, which attach to the 
P10, P11 and P12 connectors on the TMAU. The PCBs that can be installed into a DK40i KSU are 
shown in Table 3-4.
Table 3-4 DK40i Base KSU PCBs
Toshiba recommends installing the Base KSU option PCBs, K5RCU2, K5RCU or K4RCU3 and/
or KSTU2, before mounting the Base KSU on the wall. Install the Expansion KSU per Page 3-9, 
then install the Expansion KSU option PCBs.
The Base KSU slots 00~14 are automatically assigned the following codes in Program 03 when 
the system is turned on and the Base KSU PCBs are installed.
Slot 00: Code 91 without K4RCU3; Code 92 with K4RCU3; Code 98 with K5RCU2 or K5RCU
Slot 11: Code 62 eight digital telephones with OCA/DIU, 64 for OCA/DIU/DSS.
Slot 12: Code 11 for TCOU, 16 for TDDU or 77 for TBSU (four loop, four DID lines or two BRI 
circuits).
NoteIf installing TBSU, set each BRI circuit for station side or line side before installing more 
PCBs. Each BRI station circuit uses two station ports and each BRI line circuit uses two 
CO lines.
Slot 13: Code 31, four KSTU2 ports
Slot 14: Code 81, four TCIU2 circuits

Expansion KSU PCBs
A DK40i Expansion KSU from the factory does not come with any PCBs installed. (See Table 2-3 
on Page 2-3 for a list of PCBs supported by the DK40i Expansion KSU and Chapter 7 – DK40i/
DK424 Universal Slot PCBs for detailed descriptions/installation instructions.) Toshiba 
recommends that PCBs which support electronic, digital or wireless telephones be installed into 
slots 15 and 16 because slots 17 and 18 cannot support speaker Off-hook Call Announce (OCA) or 
Data Interface Units (DIUs) or more than 8 wireless handsets. See “Base/Expansion KSU 
Compatibility” beginning on Page 2-3 for configuration information for DK40i PCBs.
PCB Hardware/Software Options
PCBs can be configured for a variety of hardware and software options. Hardware options are 
defined as either internal (generally related to optional PCB subassemblies) or external (related to 
connection of peripheral equipment, such as background music, voice mail, etc.). Hardware and 
software options for each PCB are identified in the individual PCB installation procedures in this 
chapter.
PCB Hardware Options
Each PCB must be configured for the applicable hardware options prior to installation of the PCB. 
Configuration instructions for internal hardware options are provided in the individual PCB 
installation procedures in this chapter and Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring. 
Configuration instructions for external hardware options are provided in Chapter 10 – Peripheral 
Installation.
PCB Software Options
After installation of the PCBs in the KSU, configure the PCBs for software options through 
programming. A programming overview for each PCB is provided in this chapter. Refer to the 
Strata DK Programming Manual for more detailed programming instructions.
PCB Installation/Power Supply Considerations
Before installing any PCBs, make sure the power supply has been tested, and the ground has been 
checked. (See “AC Power and Grounding Requirements” on Page 3-4.)
PCB Wiring
See “MDF Wiring Diagrams” on Page 3-41 in this chapter for DK40i Base KSU wiring and 
Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring for Expansion KSU wiring. See Chapter 16 
– Strata AirLink Systems for RWIU wiring.
Digital Telephone Circuits
The eight digital telephone circuits that come standard with the system are integrated into the 
DK40i motherboard in the Base KSU. These circuits are identical to the digital circuits found on 
the PDKU. The motherboard does not have to be configured for the digital circuits to operate. For 
wiring, see “MDF Wiring Diagrams” on Page 3-41.
WARNING! To avoid electrical shock, make sure that the power supply is OFF whenever 
removing or installing PCBs.
