DK40i Installation
KSU Mounting Considerations

Strata DK I&M 6/00
6. The TCOU or TDDU cards have a green and yellow wire with a two-prong spade on the end.
Slip the spade under the second screw from the right on the power supply
).
7. If applicable, install KSTU2 Standard Telephone Interface Unit. The KSTS2 comes pre-
installed onto the KSTU2. Then install both boards into the DK40i Base KSU (see
, beginning on
).
8. If applicable, install the K5RCU or K5RCU2 or K4RCU3 (which provides Automatic Busy
Redial and DTMF tone detection) into the Base KSU (see
9. If applicable, install the KKYS (which provides built-in Auto Attendant) onto the K5RCU or
K5RCU2 or K4RCU3.
10. If applicable, install the TSIU Serial Interface PCB into the KSU (
).
If the TSIU is used for SMDR or TTY, then the PIOU/PIOUS SMDR/TTY output is not
active.
Testing the System’s Power Supply
If the “AC” or “DC” LEDs fail to light in Steps 1 or 3, see
–Case 1.
1. Plug the AC power cable into an outlet (see
). The “AC” LED on the power supply
lights green.
2. Turn On the DC power switch for the TPSU16 power supply (see
). The “DC” LED
on the power supply lights green.
3. Using a voltmeter or other device which checks voltage, measure the voltages referenced to
frame ground (FG) at the P16 connector pins (test points) located on the motherboard. The
voltages should fall within the ranges below.
♦
Yellow-green, black, and green wires: 0V
♦
Two yellow wires: -27V
♦
Range: -25.94V~-28.66V
If the voltages do not fall within the ranges, unplug the DC power pins from the P16 connector
and measure again at the same location; if the ranges remain unacceptable. See
Circuit Breaker Reset Procedure on Page 7
–Case 2.
