INSTALLATION PROCEDURE
This NAP explains the cable connection of SMDR equipment.
Note:The IOC circuit card (PH-IO24), which has four RS-232C interfaces, can be mounted in the slot Number
3 and/or 2 of the LPR.  Consequently, the system can have maximum eight ports for the RS232C terminals.
Figure 018-1  I/O Port Interface
The SMDR RS-232C interface specifications are:
Synchronization—Asynchronous
Data Speed—9600 bps (maximum)
Code—ASCII 7-bit + Parity Bit
Maximum Distance—15 meters (50 feet) without Modems.

Revision 3.0
CHAPTER 4 SYSTEM STARTUP
1. GENERAL
This Chapter describes the method to start up the system initially after completion of the installation of the PBX,
and the method to check as to whether the system has started up normally. Before beginning the system startup,
thoroughly read Section 2., “PRECAUTIONS BEFORE BEGINNING SYSTEM STARTUP” of this Chapter,
and observe the precautions while performing the system startup. Failure to so may delay the system cutover or
may result in damage to the system equipment.
2. PRECAUTIONS BEFORE BEGINNING SYSTEM STARTUP
1. The system is to be started up using the basic system data.
2. When starting up the system, it is necessary to start up the MAT.
3. The following preparatory steps must be completed before the tests are begun:
All circuit card switches should be correctly set.
Flat cables should be securely connected.
CHAMP connectors should be securely connected.
All connector-ended cables should be secured at both ends.
The –48 V (Blue) and G (Red) power supply leads must be correctly connected.
An earth lead (less than 10 ohms) must be connected to the communication ground.
The installer should confirm at this point that all installation steps have been completed.
4. Do not place any object (a tool, manual, etc.) on top of the Module Group or within a unit (module).
An object such as a book, when placed on top of the Module Group, will adversely affect heat dissipa-
tion from the Module Group.
If an object placed on top of the Module Group or left within a unit (module) falls out, it may cause
backplane pins, circuit cards, etc. to short-circuit.
5. Before initially turning ON power to the system, read the Power On Procedure (NAP-200-019).
Until the normal operation of all circuit cards has been confirmed, leave power ON only during testing.
6. Observe the temperature in the switch room.
Does the air-conditioning function properly at night?
Does the temperature fluctuate constantly because people go in and out frequently, or rise above the rec-
ommended level due to excessive heat being generated by any single piece of equipment?
The fan should be left ON constantly until the installation tests are completed.
7. A floppy disk (FD) copy of the programmed Office Data should be created. If a backup is not made, and
the contents of the Data Memory are accidentally altered or destroyed, all the Office Data will have to be
programmed again.

Revision 3.0
SYSTEM STARTUP
8. If any portion of the Office Data (especially data related to ringing patterns) has been changed via com-
mands “ARTD”, “AKYD”, or “ASYD”, the system must be initialized and tests involving the changed data
must be performed.
9. After the system is initialized, perform the following.
Set the current date and time using MAT command “AT I M”.
When the system is initialized, the system begins operating in Day Mode. To change over to Night
Mode, depress the NITE key on the Attendant Console.
If no Attendant Console is equipped, the system begins operating in night mode.
10. The following cross connections must be made at the MDF:
Complete necessary cross connections by extracting the related circuit cards from their mounting slots
or by disconnecting the circuits with a cut plug if test springs are in use.
If the connection to a D
term is made incorrectly, the electronic fuse of the circuit card will blow out.
(Repair Method:  Correct the cross connections and flip the MB switch on the card Down-Up-Down).
While a test is in progress, do not perform cross connections without first consulting with the person
conducting the test (Ringing signal:  AC 20 Hz, effective value 90 V, may be flowing through the termi-
nals).
Remove all temporary cross connections after the tests have been performed (If Office Data was as-
signed for test purposes, restore the original Office Data).
11. Observe the following when connecting cables:
Before connecting or disconnecting the control cable (Front & Backplane), turn OFF the power to the
Module Group (LPM / PIM etc.).
Before connecting or disconnecting a CHAMP connector, turn OFF the power to the Module Group.
This will prevent an accident from occurring in the event that a metal object such as a screw, screwdriver,
etc. accidentally contacts the backplane circuitry or pins.
When connecting or disconnecting the connector cable of the Attendant Console, first set the MB switch
on the ATI circuit card to the UP position, then connect/disconnect the cable.
12. Precautions when Handling Circuit Cards
When handling a circuit card, use a Field Service Kit to protect against static discharge (example:  3M
No. 8012 Portable Field Service Kit; available from NEC).
When touching a circuit card, be sure to wear the grounded wrist strap provided with the Portable Field
Service Kit.
Set the MB switch to the UP position and extract the circuit card from its mounting slot.
When holding a circuit card with bare hands, do not touch the component mounted side of the card or
the connector portion.

SYSTEM STARTUP
When placing a circuit card on a table or other flat surface, spread out a conductive sheet and set the card
on the sheet.
Set the MB switch of the circuit card to the UP position and confirm its mounting slot
 (Note). Then insert
the card into its mounting slot.
Note:Confirm that the color of the card puller tab is the same as the color of the label showing the Slot Number.

Visual Inspection Check whether any pins are shorting on the backplane of 
each Module.
Check whether any foreign matter such as a cleaning fluid 
residue is present on the connector portion of the circuit 
cards.
On each circuit card equipped with ROM (CPU, etc.), 
check whether any pins of the ROM are bent or improperly 
seated.
Leave all circuit cards inserted 
halfwayMount all circuit cards (including PWR Supplies) in the 
Module, leaving them inserted only halfway. (They should 
not be inserted into their connectors.)
Check input voltage Check insulation across the -48 V and G terminals on the 
power receiving terminal of the Base Unit.
Turn power to the rectifier ON and check the voltage (DC 
-48V ± 5V) and its polarity on the power receiving terminal 
of the Base Unit.
Turn ON Fan Units Turn FAN UNIT ON.
Verify that air is blown upwards.
If the Fuse blows, the input polarity is reversed.
Turn OFF the FAN UNIT.
Correct polarity, replace the fuse and turn FAN UNIT ON.
Verify that the FAN blows air upwards.
Check PWR Supply Check the Power Supplies for each Module one at a time. 
Check Steps:
1. Turn circuit breaker OFF and insert the PWR Supply.
2. Turn circuit breaker ON (See Note).
3. Various lamps (Green) illuminate.
4. Observe the PWR Supply for a while and confirm that 
nothing abnormal (unusual smell, smoke, etc.) occurs.
5. Turn the circuit breaker ON/OFF a few times and 
observe the condition.
6. Turn the circuit breaker OFF and remove the PWR 
Supply.
Note:If a Module is equipped with dual PWR Supplies,
they must be turned ON/OFF simultaneously.
