STEP 4 Analyze the displayed system messages.
After STEPs 1 through 3 are performed, the system messages [7-U] and [7-V] will automati-
cally display. Make sure that no errors occurred during the PLO changeover process.
12.2 Initialization

12.2.2 System Initialization by Turning ON Power Supply
This initialization executes when the power supply to the system has stopped.
Follow the procedure in Table 6-10.

Handling
Precautions Required
Turn ON power supply at PWR cards.
END
Confirm all switches are turned OFF on PWR cards.
Power supply to the PBX is restored.
Confirm input source power to the PBX is normal.
Execution of Initialization
Confirm the following lamp indications:
[CPU DSP#0] CPU OPE: steady-green
IMG0-3: flash (green)
[CPU DSP#1] IMG0: flash (green)
Clear alarm by pressing ALM RST key on TOPU.
Use ATIM command to adjust date and time.
Refer to Section 12.3.
Check INPUT voltage is nor-
mal at power terminals.
Refer to Section 12.3.
When initialization completes,
ACT0 lamp lights green and
ACT1 lamp goes OFF on
EMA (PH-PC40) card.

12.2.3 System Initialization by Key Operations on TOPU
Table 6-11 shows the system initialization procedure. Figure 6-57 shows the initial program load con-
ceptional diagram.
Table 6-11  System Initialization Procedure Types
TYPE DESCRIPTION
Procedure #1
(Table 6-12)System Initialization without Loading Whole system is initialized. All communications are 
forcibly released. System restarts with current Main 
Memory Files and Office Data Files that exist on DRAM.
Procedure #2
(Table 6-13)System Initialization with Office Data Loading Whole system is initialized. All communications are 
forcibly released. System transfers Office Data Files from 
HDD to DRAM. System restarts with the transferred 
Office Data Files and the current Main Memory Files.
Procedure #3
(Table 6-14)System Initialization with Program Loading Whole system is initialized. All communications are 
forcibly released. System transfers Main Memory Files 
from HDD to DRAM. System restarts with the 
transferred Main Memory Files and the current Office 
Data Files.
Procedure #4
(Table 6-15)System Initialization with Office Data and 
Program LoadingWhole system is initialized. All communications are 
forcibly released. System transfers both Main Memory 
Files and Office Data Files from HDD to DRAM. System 
restarts with the transferred Main Memory Files and the 
transferred Office Data Files.
Procedure #5
(Table 6-16)System Initialization by Phase 1 Restart System is initialized. All communications, except for the 
following two-way connections that have already been 
established, are forcibly released:
 Basic two-way connections (STN-STN, STN-TRK, 
TRK-TRK)
 Fixed connections
 Two-way connections established on a Fusion Link
Note 1:
STN-ATT connection is not included in
the two-way connection list cited
above. These kind of calls are forcibly
released once the initialization exe-
cutes.
Note 2:When a calling party hears the Ring
Back Tone, the ORT is additionally
provided, and the call is placed into the
Dial Tone (DT) connection.

Note 1Note 2
Note 1:This figure assumes that the CPR is equipped with PZ-IO27 (HDD/FDD), in place of PZ-
IO28. If PZ-IO28 is used, the MB (Make-busy) key is not furnished on the card.
Note 2:The LED indication cited above is only an example. The actual indicating patterns (ON/
Flash/OFF) may vary, depending on the system configuration.
To initialize the system, operate the keys
shaded here.
To confirm the imposed system initialization, check
the lamp indicators shaded here.
