a. Disconnect the electrical supply, or
b. Remove the casualty from contact with the electrical supply by pulling at
his dry clothing. Do not move the casualty unless it is necessary.
2. If the casualty has stopped breathing, apply mouth-to-mouth resuscitation
immediately (see artificial respiration below).
3. Call for help.
Artificial Respiration
1. Clear throat of water, food or foreign matter.
2. Tilt head back to open air passage.
3. Lift jaw up to keep tongue out of air passage.
4. Pinch nostrils to prevent air leakage when you blow.
5. Take a deep breath. Seal your mouth around casualty's mouth, blow until you
see chest rise.
6. Remove your lips and allow lungs to empty.
7. Listen for snoring and gurglings, signs of throat obstruction.
8. Repeat mouth to mouth breathing 10 to 20 times a minute. Continue rescue
breathing until casualty breathes unaided.

Control Panel Lights
Basic Check:
The red BASIC CHECK light indicates a failure in the processor. There is a danger of data being destroyed. Save the status of the machine and call the service
representative. The BASIC CHECK light is also on when the power-service mode
switch is in "service" position. The power-service mode switch is located in the
IBM 4321 or 4331 processor and can be operated only by service personnel.
System:
The green SYSTEM light is on when instructions are being processed or when
I/O operations are in process.
Wait:
The amber WAIT light is on when the wait bit in the current PSW is set. This
means that the processor is idle, that is, not processing instructions or handling
I/O operations. The setting of the wait state is controlled by the operating system.
Usually the processor awaits the completion of data transfer from an I/O device.
The processor leaves the wait state upon an interruption.
2":A
4331,Process0rOperating Procedures
Power in Process:
The POWER IN PROCESS light indicates that a power-on, or power-off
sequence is in progress.
Power Complete:
The green POWER COMPLETE light comes on when the power-on sequence is
completed.
Control Panel Keys
IML:
Pressing this key while power is on starts the IML (initial microcode load)
sequence.
Lamp Test:
The LAMP TEST key tests the control panel lights and the lights of the mM 5424
Multifunction Card Unit (if installed). When this key is pressed, the check lights
on the panel turn on. The lights go out when the key is released.
Power Off:
The POWER OFF key starts the power-off sequence. If during this sequence a
power failure is detected, a reference code is displayed and the power-off
sequence is halted, however, power is not turned off. Note the reference code for
the service representative's use and press POWER OFF a second time to complete
the power-off sequence.
The power-off sequence can also be initiated by operating the POWER-ON/OFF
toggle switch located at the righthand side of the IBM 4321 or 4331 Processors.
Note: The power-off sequence clears the contents of all storages. Power off is
complete after 5 - 7 seconds.

The keyboard has three types of keys:
•
Alphameric keys
•
Cursor and tabulator keys, backspace key ~ and space bar
•
Function keys
The keys and their functions are described on the following pages.
Alph~meric
Keys
The alphameric keys are used to enter messages and data,lmd to call up displays.
These keys are typamatic, that is, they repeat th1:!ir function as long as they are
held down. The second character on some alphameric keys can only be used in
conjunction with the SHIFT or the ALT key (sec "Function Keys"). The position
of the alphameric keys on the keyboard is shQwn above.

•
that~indicates \vhere
When a character is entered, it appears just above the. cursor:
The cursor is automatically positioned ready for the
•

the next character
nex~
entry.
You can position the cursor manually by means of the five cursor keys. To
prevent interference with internal operations, these keys can be locked. For
example, during IML, or when the cross indicator (see "Machine Status Display," line 25) is on the screen, you cannot free these keys. The system
4331 Ptocessol' Operating Procedures
returns them to your control when the internal operation is completed.
The five cursor keys are typamatic, which means you can "run" the cursor by
holding the key down. When the cursor reaches the edge of the screen, it
returns (or wraps around) to the opposite edge of the screen and continues
moving in the same direction as long as the key is held down.
To alter data displayed on the screen, position the cursor under the data to be
changed, type in the new data, and press ENTER.
•
The cursor can be moved by the space bar and the backspace key.
Cursor Kcys
The cursor can be moved in the following ways:
Cursor to New Line:
The cursor moves to the first unprotected character position (*) in the next lower
line, traversing all protected lines before finally returning to the first line with an
unprotected character position.
Cursor Up:
I.PA.~E~.
The cursor moves upward in the same character column. Finally it returns to the
bottom of the screen and repeats the same path upwards .
.....
Cursor Down:
The cursor moves downward in the same character column. Finally it returns to
the top of the screen and repeats the same path downwards.
Cursor to Left:
EJ
The cursor moves right to left and line by line upwards. Finally it returns to the
bottom right-hand corner of the screen and repeats the same path. The backspace
key performs the same function as the cursor-to left key.
Cursor to Right:
EJ
The cursor moves left to right and line by line downward. Finally it returns to the
top left hand corner of the screen and repeats the same path.
Tabulator Kcys, Backspace Key, Space Bar
These keys cause the cursor to move in the following ways:
Tabu/ator:
B
The cursor moves right to the first unprotected character position. If held down,
it traverses all firshcharacter positions of unprotected fields in a left-to-right,
top-to-bottom direction. Finally it returns to the leftmost character position of the
topmost unprotected field.
Chapter 2. Communicating with the System
2-7
Back Tabulator:
The current position of the cursor affects the operation of the back tabulator key
When the cursor is in an input field at a location other than the first character
location, the back tabulator key repositions it to the first character position in the
field. When the cursor is in a protected field, or at the first character position of
the input field, the back tabulator key repositions it to the first character position
of the first input to the left of the present field.
Using this key together with the ALT key repositions the cursor to the home position, that is to the first unprotected position on the total display.
Backspace:
The cursor moves right to left and line by line upward. Finally it returns to the
bottom right-hand corner of the screen and repeats the same path. The
cursor-to-Ieft key performs the same function as the backspace key.
SpaceBar:
The cursor moves to the right and inserts a blank character.
Function Keys
ModeSEL/DIAG:
Pressing MODE SEL causes the mode selection display to appear on the screen.
This display lists the available operating modes. These modes, and how to use
them, are described in Chapter 3.
Mode selection can be requested at any time; it does not affect the state of the
machine other than breaking into a chain of messages that is about to be written
onto the screen. The display on the screen when MODE SEL is pressed is automatically stored by the system and can be recalled later. Do not, however, keep
this display, nor any other manual operations display, on the screen any longer
than necessary as, during this time, the system can neither use the screen nor
record errors.
The DrAG (diagnostic) function of this key is for service personnel only. For
operation of this key during a color convergence test, see Note following
description of CRG DPL Y.
CNCL:
CNCL (cancel) is used to stop operations that have been started but not completed (the ENTER key has not been pressed). The operation is terminated
according to the mode that the screen was in when data entry started:
If the screen was under control of the system, and if the command set is 3270,
the message or reply is deleted. If the command set is 1052, the message or
reply is marked with an asterisk.
•
If the screen was in manual operations mode, the display is deleted, control
returns to the system and the last full picture that was displayed before manual operations began is restored to the screen. For operation of this key during

The CHG DPLY (change display) key causes the screen display to change from
the system message buffer to the manual operations buffer, and vice versa. During
system operation, the screen and keyboard are made available to the operating
system. During manual operation the screen and keyboard (except START, STOP
and INTR) are made available for manual operation.
Note on Color Convergence:
When a color convergence test is running on another terminal attached to your
4321 or 4331, you will get an abnormal response to pressing MODE SEL/DIAG,
CNCL, or CRG DPLY. Instead of the expected result, the message MODE SEL
CANCELS CONV comes up. If you press MODE SEL while this message is on
the screen, MAN OP is displayed and manual operations can be carried out. Note,
however, that the color convergence test on the other terminal is terminated. If
you press DIAG, CNCL or CHG DPLY, the message CONVERGENCE ON
PORT nn is displayed but there is no further action.
INTR / Line Disc:
The INTR (interrupt) key is used to request an external interruption.
The LINE DISC (line disconnect) function of this key is for service personnel
only.
Erase Input:
Pressing the ERASE INPUT key erases all input fields on the screen. The cursor
moves to the first character location available for entering data.
Erase EOF I SP MIO:
Pressing the ERASE EOF (Erase End of Field) key erases character positions in
the input field in which the cursor is located. All character positions from the cursor location to the end of the field or line are erased. The cursor does not move.

Copy:
I I
COpy
Pressing the COpy key during manual operations (MAN) produces a printed
copy of the screen contents (all lines except line 25). The copy is printed by the
3287 console printer (if attached) on the port with the lowest address.
Note: Programmed operations on the 3287 terminal printer have priority over the
COpy key function. This means that the COpy key has no effect when the print
buffer contains data that has not yet been printed. The COpy key becomes
effective as soon as data in the print buffer has been printed. If there is a
dead-lock (such as, the print program hangs, or a similar error), the power switch
on the printer should be turned off and on again. This action resets the entire
print buffer and enables the COpy key function.
Shift:
There'is a SHIFT key on each side of the keyboard. Both SHIFT keys serve the
same purpose. Pressing a SHIFT key causes:
•
The upper character of a key with two characters to be entered.
•
The upper case of an alphabetic character to be entered.
The shift symbol is displayed in line 25 when this key is depressed. In TEST mode
the symbol is not displayed.
Lock:
Press the LOCK key to shift and lock the keyboard in upper case. To release the
shift lock, press one of the SHIFT keys. The shift symbol is displayed in shift lock
mode.
Reset:
Press RESET to free the keyboard when it is locked. When the WAIT indicator is
shown (because some action was initiated), the Reset key will cancel this action.

Keyboard Lock and Keyboard Inhibition
The status of the keyboard depends mainly on the mode of operation.
•
3270 Mode
In 3270 mode the keyboard is normally free to type in data until the operator
initiates a system operation, which inpibits the keyboard, that is, the keyboard
does not accept any further input until the initiated operation is completed.
The keyboard is also inhibited when data entry into a protected field is
attempted. The reason for inhibition is shown on line 25. The reset key is used
to reset the inhibition.
•
1052 Mode
In 1052 mode, the keyboard is normally locked and it must be unlocked by a
read inquiry command which is usually issued by the operating system when
the REQ key is operated. In locked state, the cursor is displayed in the upper
lefthand corner. Operating the RESET key does not change the locked state.
The read inquiry command displays the cursor in line 19 position 2, sounds
the audible alarm, and PROCEED is displayed. Any inhibit state of the keyboard is displayed on line 25. Inhibition due to errors (such as writing into a
protected field) may be reset by the RESET key. However, when a system
action has been initiated (e.g. the REQ key has been pressed) and the wait
indicator is on, the RESET key resets not only the keyboard but also cancels

3-1
Loading the Control Diskette
For machines without the "diskette drive" feature, the control diskette is located
in the drive unit accessible from the table top of the IBM 4321 or 4331 Processor.
Any handling of the control diskette is not required except by the service representative. The control diskette must never be removed, nor must the sliding door
be opened while the system is in operation.
For machines with the "diskette drive" feature, the control diskette is under the
covers of the IBM 4321 or 4331 Processor, while the drive unit accessible from
the table top is available for I/O operations.
Before loading the diskette, check that it is undamaged. Do not use a damaged
diskette until a service representative has inspected it.
1. Depress the latch of the sliding door and open the sliding door at the table
top. This automatically opens the mounting plate of the diskette.
2. Grasp the diskette by the white label and remove it from its envelope.
3. Lower the diskette carefully into position behind the mounting plate until it
comes to rest on the locating surfaces.
@
Permanent labels
at the top and
facing the front
of the processor.
4. Close the sliding door fully. This will close the mounting plate automatically.
The centering cone must slide freely into the center of the diskette. If not,
check that the diskette is seated against the locating surfaces and that it is
undamaged.
5. Store the empty diskette envelope where it will not become damaged or dirty.
6. If a diskette has been exposed to temperatures outside the machine's environmental range, allow five minutes before use.
7. When receiving diskettes, check for carton and diskette damage.

4331 Processor Operating Procedures
Switching Power On
Before switching power on, ensure that nO" person is exposed to risk and that all
equipment covers are shut. Also ensure that power switch on the display console
is in the "on" position and the Normal/Test switch is set to "Normal." If the
Normal/Test switch is in the "Test" position the console is not available for the
program and forces a "wait" condition.
Press the power-on toggle switch at the righthand side of the 4331 Processor.
Above this power-on switch is a red power-active lamp that comes on about one
second after the switch has been pressed. At this time the POWER IN PROCESS
lamp on the control panel also comes on.
The 4321 or 4331 Processor does not distribute AC primary power to the
attached I/O devices. Each type-numbered unit has its own power-on switch and
its own power-cord. In most cases power must be turned on at each unit individually (except when the power interface feature is installed, in which case the connected units power-up together with the processor). On some units, such as the
3310 disk drives or the 8809 tape drives, the optional power interface cannot be
installed. You must turn on power at the power switches of these units.
Ensure control diskette is
inserted in system diskette drive.
Switch POWER ON.

Switching Power Off
The system power must always be switched off at the processor before power is
switched off at the I/O devices. The reason for this sequence is that some devices
(3310, 3340, 3370) maintain error and usage counters, which would be lost if
power were switched off at these devices first.
The following procedure ensures that all error and usage counters are saved on
the system diskette before power is switched off.
1. Ensure that all jobs have been completed.
2. Wait until the Wait light on the console comes on.
3. Press STOP on the control panel and wait until the MAN indicator (manual
mode) appears on the screen.
4. Press the Power Off key on the control panel. The processor will save all
counters before it starts the power-down cycle.
5. Switch the power off at the I/O devices.

Address Compare
The "address compare" display allows you to stop the machine when a reference
to a specific main storage location is made during system operation. This feature is
useful, for example, in finding and diagnosing system errors. Address Compare
stops are possible on real addresses only.
For virtual addresses in System /370 Mode, use the Display/Alter Main Storage
Virtual (DV) option (see "Main Storage Virtual" in this chapter) to display the
corresponding real address and work with that address.

the word SELECTION at the bottom of the screen.
2. Press ENTER.
3. Enter one of the following three codes under FUNCTION:
3-12
N
(Normal) The address compare mode is turned off and normal
processing continues.
s
(Stop) The machine stops when the address has been found (see
"Compare Type," step 4 below, for the search conditions).
y
For maintenance purposes only. A synchronization pulse is issued
when the address match occurs. The machine does not stop.
4331 Processor Operating Procedures
4. Enter one of the following four codes under COMPARE TYPE:
A
(Any) The search address given in column 3 is compared with all
addresses used in any references to storage.
C
(Instr Count) The search address is compared only with
addresses used for fetching instructions.
D
(Data Store) The search address is compared only with addresses
used to store data.
I
(1/0 Data) The search address is compared only with addresses
used in transferring data between main storage and I/O devices.
5. Enter the search address under STORAGE ADDRESS. This can be up to six
hexadecimal characters. If you enter less than six digits, the processor supplies
the appropriate number of leading zeros to make a six-digit number.
All addresses can be compared, including those where the processor stores
updated information. If, for example, you select address 80 (where the interval timer is stored) a match occurs each time the interval timer is updated, and
the processor then stops.
Error Messages:
Invalid Character is displayed if you enter either an incorrect selector
character or a non-hexadecimal character as address.
Invalid Address appears if you specify an address that is outside main storage size.
Incomplete Entry is displayed, and the cursor is set below the next character if, during fast selection, you specify incomplete specifications.
6. Press ENTER. The "address compare" display disappears from the screen,
and your specifications are displayed in line 22 of the Machine Status Area as
a reminder that address compare mode is set.
7. The processor stops after completion of the instruction that was in progress
when the address match occurred. The effect is the same as if the Stop key
had been pressed. When the Start key is subsequently pressed, processing
continues with the next sequential instruction.
With instruction count mode set as address compare criterion, the processor
stops always upon completion of the instruction that caused the address
match.
When the location of a branch instruction is the address compare target, the
stop occurs upon completion of the branch instruction, that is, after the
branch is taken. When the Start key is subsequently pressed, operations
resume at the next sequential instruction if no branch was taken, or at the
branch address if the branch was taken.
Chapter 3. Procedures
3-13
Note: When the location of the instruction that immediately follows the
branch instruction is the address compare target, then two stops are provided
for the seven most commonly used branch instructions. The first stop occurs
after the branch is taken (provided the instruction does branch). The second
stop occurs at the actual address compare target, that is, at the instruction that
would have been executed next if no branch had occurred. The stop occurs at
the completion of that instruction.
The following branch instructions have two stops:
BAL, BALR, BCR, BXH, BXLE, BCT, BCTR

mode to be turned off.
s
(Hard stop ) This code causes the machine to enter the
"checkstop" state as soon as possible after the detection of a
machine-check or channel-check condition. A machine-check
interruption is any machine error that would cause a machine
check interruption in normal mode. A channel check is any
machine error that would cause an 110 interruption indicating
Channel Control Check, Interface Control Check or Channel
Data Check in normal mode.
(Note that a check-stop requires a program or clear reset to
recover).

system.
Note: Selecting any of the options causes the processor to stop. For this reason
START must be pressed to resume operations, regardless of whether any alterations have been made or not. The displayed facility remains on the screen until
the Cancel (CNL) key (or Change Display Key) is pressed.
Error Messages:
Invalid Character indicates an invalid selector, hexadecimal or binary character.

specified if, during fast selection, you entered incomplete specifications.
Invalid Address indicates an address that exceeds the storage size of your
machine.
Check Stop. Ifa CHECK STOP occurs and the selected function was not
reset it may be caused by a PSW loop. You can recognize a PSW loop only by
two symptoms which are "lack of activity with SYS indicator on ... " and "the
stop key does not work." In this case perform PROGRAM RESET and check
the PSWs.

The remaining lines on the screen contain items for which usually two options are
offered. To change these values, proceed as follows:
1. Press the PF 1 key to move the large arrow in the left margin of the screen to
point at the item you wish to change. You must hold down the ALT key and
then press the numeric key 1 (this activates the PFI function.)
2. Press the PF2 key to move the small arrow pointing at one of the options (in
the right-hand columns) to the required value. If the small arrow is missing,
the associated parameter is not relevant to this configuration. Some combinations of parameter values are invalid. If such a combination is selected, a
warning message is given and the change is rejected.
3. When you have finished updating the options for the line presently displayed,
press the PF4 key and the display for the next line will appear. A message
appears if the equipment corresponding to the next line is not installed. If the
present display was for the last line, the display for the first line appears
again.
4. When all updating is finished, press ENTER. If you intend to finish the procedure without changing anything, press PF3.
Changes in the displayed configuration are required only when your installation
uses switched lines where you may have communications with various different
types of terminals and you may have to adjust your equipment to the needs of the
remote terminal. The following describes the start/stop line parameters and when
they are required.
Unit Exception Suppress must be set to yes when the remote station is a 2741 or
equivalent. The 2741 sends a circle-C character as the only ending character it
"knows" and this would always cause a unit exception which breaks a command
chain unless suppressed as recommended.
Read Interrupt should be set to "yes" when the program (in your system) is to be
authorized to issue a break command to the remote station to stop this station's
transmission. If read interrupt is set to "no,~' a break command is rejected. The
issuing of a break command is possible only on duplex facilities (4-wire line or
duplex modem on 2-wire line).
34-,34
4331>Processor Operating Procedures
Write lnterrupt should be set to "yes" if you want to authorize the remote station
to stop your line's transmission. By setting "yes," your line will accept the break
signal from the remote station. This requires duplex facilities (same as for read
interrupt).
Select Standby should be set to "yes" when your leased or privately owned line is
damaged and you are forced to change to a switched line to sustain communication. The standby can be used only when the modem has the switched network
backup capability.
Answer Tone should be set to 2025 Hz if the modem of the remote station is a WE
202 (Western Electric) type modem. This selection sets the integrated modem in
the 4331 to provide the answer tone which the WE 202 requires. Select 2100 Hz
in all other cases, or if the modem of the other station is unknown.
Note: The answer tone selection appears in the display only when your line is
equipped with the integrated modem, otherwise the bottom line of the display is
omitted.

The following describes the SDLe line parameters and when they are required.
Select Standby allows you to select the switched network backup facility of your
modem (provided the modem is so equipped). By selecting yes, the modem uses a
switched line instead of the normally used leased or privately owned line. Select
yes when the normally used line is damaged.
Data Signaling Rate Selector allows you to set the modem to the higher or lower
of two clocking speeds if the modem is properly equipped. Normally the higher
speed is set. However, if the number of error incidents and therefore the number
of recovery or retransmission actions becomes excessive, you should select the
lower speed. With a lower speed a "noisy" line can still be used. You may also
have to change the speed (the signaling rate) to adjust to the speed of a remote
station.
NRZI allows you to change from the normal non-return-to-zero inverted (NRZI)
method of encoding digital signals to a method where the signal is not inverted
when successive zero bits appear.
Some modems are sensitive to certain steady bit patterns and may thus require
either NRZI or not-NRZI to function properly (check the modem manufacturers
information for the applicable mode). Crypto-units which encipher/decipher data
may likewise require one or the other mode. Because SDLC-transmission is
bit-oriented, bit synchronization is important. Therefore, if too many errors occur,
check that the mode is correct.

Data Signal Rate Selector allows you to set the modem to the higher or lower of

change the speed (the signaling rate) to adjust to the speed for a remote station.
(high speed = 1200 BPS, low speed = 600 BPS).
Data Code. ASCII code should be selected whenever the remote station requires
this type of line code, otherwise EBCDIC should be used. Ask the system programmer when in doubt or ask the operator at the remote location.
EIB Mode allows you to specify that an error index byte (EIB) is to be set into
storage adjacent to each ITB, ETB, and ETX character that is received. The
intermediate text block (ITB), end of text block (ETB), and end of text (ETX)
character are inserted into the message by the remote station to divide the transmission into smaller portions. In this way EIB mode reduces the amount of code
that is to be retransmitted for recovery because only the text up to the last index
byte must be sent again (ask the system programmer for details as to when to use
ErB mode).

ENTER-ACTIVATE ADDRESS (ES) / PF3-EXIT WITHOUT UPDATE
The display lists all lines that use BSC protocol but only those lines. This explains
why the addresses do not necessarily appear in sequence (in our example, line 31
is followed by line 35 because lines 32, 33, 34 are Non-BSC or do not exist).
The display is required only when your communication lines are part of a
mUlti-point network and participate as tribut~ry stations. Tributary stations can be
selected or polled from a master (remote) station. For this reason they must be
"known" by an address and this address is normally assigned once at installation
time.
Every line has two tributary station addresses which may (but need not) both be
used. The idea is to give a group of lines a group address, for example address 40.
If address 40 is given to four lines, these four lines could simultaneously receive
data from the master station (when addressed by their group address). The display contains the group address 40 as default value for each line. You may leave
these addresses or change them, as you like. Besides such a group address~ each
line can get an individual tributary station address, for example 41, 42, 43, etc,
and will then be separately addressable. The place to enter such addresses is blank
in the display, but marked XX in our example for clarity.
You may enter the first address (leftmost two digits) as group address and the
next two digits (marked XX) may represent the individual station address, or vice
versa. The addresses are accepted in either position. If you enter only one address
(either left or right) for a line, that address is automatically assumed to apply to
both address slots. For example, if you keep the default address 40, the individual
address is also 40 (even though the space marked XX is blank in the display).
3...;42
4331 Processor Operating Procedures
Address bit 2 (counting from left to right) is used to distinguish between polling
and selection of the station. If you use the default address 40, the station is polled
with address 40, and selected with address 60.
In 3270-type addressing, the addresses for polling and selection do not always follow this rule. The exceptions for 3270 addresses 1 and 16 may be handled by the
4321 or 4331 by specifying two station addresses: C 141 (character "A") for
address 1, and 5000 (character"@") for address 16.
The cursor is located underneath the first line's left address. You may enter the
addresses in sequence (the cursor moves along) or you may pick a specific address
via the cursor movement keys.
Note: Only specific codes are valid as tributary station addresses and the display
accepts only valid codes. You may either assign the address by trial and error or
go by the following rules:
1. Do not use any of the following control characters: SOH (Hex 01), STX (Hex
02), ETX (Hex 03), EOT (Hex 37), ETB (Hex 26), ENQ (Hex 2D), DLE
(Hex 10), NAK (Hex 3D), SYN (Hex 32), or ITB (Hex IF). The Hex codes
listed here are EBCD1C. For ASCII, see the /370 reference card.
2. If the line code is ASCII (which is a 7-bit code) no value higher than hex 7F
can be used (that is. bit 0 in the byte must be 0).
3. Bit number 2 in the byte must not be 1. This rules out all addresses that begin
with 2, 3, 5, 6, A or F. This rule ensures that bit 2 can be used to distinguish
polling and selection during addressing.
When you have typed in all addresses, you may either press the PF3 key to exit
without changing anything or the ENTER key to put the change to work.
After ENTER key depression you will first see the message "update in process"
and after a while this message changes to "update done." As of this instant, the
changes are recorded on the system diskette and the changes are in effect for any
program. No IML is required.
To return to the operating system, press CANCEL or PF3.

2. Type in either P or C under the program reset field:
P
PROGRAM specifies an initial program reset and clears the following
controls to zero with valid parity: PSW, iU timer, clock comparator
and control registers.
C
CLEAR causes a clear reset (see the "Clear Reset" procedure) and
must be specified when STORAGE SIZE, NUMBER OF BUFFERS,
EMULATED DEVICE or FIRST HOST ADDRESS are changed or
this is the first load operation after power-on.
3. Specify under MACHINE MODE in which mode the system is to run: V for
VSE mode, or 3 for 370 mode.
4. If you select VSE mode, specify under STORAGE SIZE the size of storage
required. The entries "2," "4/' "8," "C" provide 2, 4, 8 or 12 megabytes of
storage. You may also specify "M," which gives you the maximum storage
size (16 megabytes), or "R," which means that the (virtual) processor storage
equals the machine storage size of the model you are using.
5. If the console is to operate in 1052 Printer/Keyboard mode, the operator
must define whether this mode should include the 3287 terminal printer or
not. If no printer is installed or if the printer is required for other than console
message printing, "N" for no should be entered. The 1052 mode will then use
the screen as the only means for message output. If the 3287 terminal printer
is to be used for console message printing, "P" for print should be entered.
This causes the 3287 on the lowest port to do the job of 1052 printing. The
address of this 3287 is now no longer available for software or local-copy
operations. If you attempt local copying, the message "Printer Not Working"
will appear at the requesting station, although the printer will work in 1052
mode. If "F" for off or a blank is entered, the console operates in 3270 operation mode. 1052 mode is required for operating systems which do not support the display mode of the operator console.
6. If the 3340 direct attachment is installed, it is always operational and one
buffer is automatically allocated by the system. You can specify further buffers to a maximum of eight.
7. Zero to 8 buffers may be specified under EMU if the disk compatibility feature is installed (at least one buffer must be specified for the feature to
become operational). If zero is specified, the feature is not activated and no
storage is occupied by microcode.
8. If you have made the disk compatibility feature operational (by specifying
EMU buffers), selec't one of the devices listed under EMULATED DEVICE.
9. If the disk compatibility feature has been activated, specify the address (three
hexadecimal characters) of the device that is host to the first emulated volume
under FIRST HOST ADDRESS.
10. If you load an operating system that does not support the host device (does
not "know" the 3310 or 3370), EMULATION-ONLY MODE = YES must
be specified. "YES" indicates to the compatibility feature that it has to perform the error logging for the host device.
3-48
4331 Processor Operating Procedures
If you load an operating system that supports the host disk ("knows" the
3310 or 3370), such as VSE, EMULATION-ONLY MODE = NO must be
specified. The operating system will then log host errors even if the host
bears nothing but emulated disks, and no host application runs.
Note: After entering (or changing) specifications for the disk compatibility
feature perform a "Clear Reset."
When you have typed in the load data, press ENTER to start the initial program
load process. At this instant the "LOAD" indicator appears and remains on until
a valid PSW is loaded, at which time the entire load display disappears.
If the IPL process is unsuccessful, the IPL display and the LOAD indicator
remain on the screen and the message "lPL ERROR" appears.
A reference code is displayed for service personnel.
The most common IPL errors are:
Load device not ready
Some other device besides the load device was made ready (should be the load
device alone)
Wrong address: for example, the address of the line printer was entered as
load address.
If you make an error while entering program load specifications the following
messages are displayed on the screen:
Invalid Character is displayed when an incorrect selector character has been
entered.
Invalid Address is displayed if an invalid "channel," "control unit," "device,"
or "host device" address is specified.
Incomplete Entry appears on the screen if no character was entered or if in
case of fast selection, the set of characters keyed in is incomplete.
Invalid Reset, Select *C* appears on the screen and the cursor is set below the
reset specification, if one of the specifications "storage size," "number of
buffers," "emulated device," "host device" or "emulation-only mode" are
changed and program reset (character "P") is specified. This occurs also if P
is specified for the first load operation after power-on.
Invalid Host Device Address appears on the screen and the cursor is set below
the host device address specification, if one of the possible host device
addresses is used, but that address was not assigned at system installation time
(or has been deleted).
No Console Printer Configured appears on the screen when 1052 emulation
mode with console printer is selected ("P") and no 3287 console printer was
assigned to any of the port addresses at installation time (or was deleted).

machine is in the stopped state when "Restart" is entered, processing starts
immediately with the program restart PSW (a fixed location in storage). If the
machine is in the operating state, the restart PSW gets control when the current
instruction has been executed and after all interruption conditions for which the
CPU is enabled have been handled.
A "Restart" is successful only when an operating system is used that takes advantage of the restart PSW or prepares a restart PSW for the explicit purpose of
restarting the system at a meaningful point.

Store Status
The "Store Status" mode enables you to make a record of the current status of
certain system resources. "Store Status" is recommended prior to loading a
standalone dump program because it saves the contents of the general registers
before they are being used by the standalone dump program. The "Store Status"
operatio,n is initiated from the mode selection display. (370 mode only.)
"Store Status" applies only to a m'achine in 370 mode. If an error occurs during
the operation, the processor enters the check-stop state.
To specify "Store Status":
1. Type S into the "Mode Selection" display next to SELECTION.
2. Press ENTER.
The "Store Status" operation stops the processor, then causes the following to be
stored in fixed locations in main storage:
•
•
•
•
•
CPU timer
Clock comparator
Current PSW
Floating point register
Control registers
General registers
When ENTER is pressed, the mode selection display remains on the screen and
the message STATUS STORED appears. The system goes into the stopped state.
3-54
4331 Processor Operating Procedures
TODEnabie
This operation allows you to determine the instant when the time of day (TOO)
clock is set. "TOO Enable" is performed from the mode selection display. To set
"TOD Enable":
1. Type Y into the "Mode Selection" display after SELECTION.
2. Press ENTER at the exact instant at which you wish to set (synchronize) the
clock. This may be, for example, the moment when the hands of the clock
jump to the full hour.
The time-of-day clock is always in the "secure" state which means that the program cannot set the clock. This secure state is only briefly removed when you
press the ENTER key, and the program will set the clock at this instant (with a
previously prepared value).
The status of the TOO clock is indicated in line 22 of the machine status area.
The TOO enters secure state automatically after "TOO Enable."

Native Displays and Printers
This display allows you to specify what types of devices are connected to the display/printer adapter, how these devices are equipped, and which addresses are
assigned to them. The display allows you to delete devices from your configuration without physically disconnecting them, and it allows you to change device
addresses or assign new devices. You can also change the keyboard type and language specification of the attached terminals.
To select "Native Displays and Printers":
1. Type MM into the "Mode Selection" display next to SELECTION. (By typing a single M you get a picture which offers ROCF subselection. ROeF procedures are described in Operator's Library IBM 4331 Processor Remote

The fourth line of the display shows, following the heading "translate tables (T),"
the keyboard layouts for the terminals to be attached and the associated national
language. Two different layouts may have been ordered: the mandatory typewriter layout and either the data entry 1 or data entry 2 type layout (these are
key-punch-like keyboards). Each keyboard type may have its own language associated or both may have the same. It is also possible that only one type of keyboard (the typewriter) was ordered for all terminals but two different languages.
Whatever the choice may have been, the mandatory typewriter layout with its
associated language is denoted as "1" and the other keyboard type and its associated language (if any) is denoted as "2" in the display. For example:
TRANSLATE TABLES (T):
TYPEWRITER (FRENCH) = 1
DATA ENTRY 2 (U.S. ENGLISH) = 2
This makes it easy for you to define the language and keyboard combination of a
terminal which you want to connect because you only need to enter a 1 or a 2 (as
applicable) in the "T" column of the terminal field. The terminal field consists of
four columns whicH define (from left to right) the port number, the device type,
the device address, and the keyboard/language combination, as follows:
PORT DEVICE ADR T
The number entered under "port" defines into which receptacle the device's coax
cable will be plugged. The cable receptacles are numbered sequent~al1y from to
15. The system expects to find the operator console at port 0, that is, it routes the
operating system messages automatically to the device connected to port 0 (using
the device address associated with port 0). The number entered under device
specifies whether the terminal is a display or a matrix printer or a line printer (e.g.
3278-2,3262, etc.). The device address (ADR) defines the number under which
the program can address this device, and theT column defines the
keyboard/language combination (when applicable).
°
Note: For terminal printers, only the language portion of the keyboard/language
combination is meaningful and effective when a 1 or a 2 is entered. For line
printers (e.g. 3289-4 or 3262) no language need be specified because line printers receive their language character set via the "load USCB operation" (operating
system). For line printers, the X may remain in the T column.
The display shows the current configuration, and you may enter your changes
underneath. In order to logically attach a device, position the cursor under the
alter field (identified by " .... ") of the corresponding port and key-in the applicable device type number.
In order to logically detach a device from the system, type "X" into any position
of the alt,er field of the corresponding DEVICE display field. When you then
press the ENTER key, Xs appear in the DEVICE display field and automatically
in the corresponding translate language (T) and device address (ADR) fields.
Pressing ENTER after you have made the necessary changes causes the new conChapter 3. Procedures

figuration to be written onto the system disk.
After changing the configuration, IML must be· performed. If you have merely
swapped two line-printer ports, you can bypass IML by operating the Reset switch
(3289-4) or the Test key (3262).
Configuration Rules and Limitations
•
A device (except line printers) may be configured (logically attached) even if
it is not physically attached. If such a device is addressed during system operation, "intervention required" is presented, and nothing else happens.
Port 0 is always reserved for the operator console.
•
A maximum of two system printers (3289 and/or 3262) may be attached in
any combination.
The Copy key addresses the matrix printer with the lowest port number.
•
Ports 8-15 can be used only if the optional feature (display/printer adapter
expansion) is installed;
Specification Errors/Messages
The following messages may appear on the screen:
Invalid Device Name: Appears if an invalid DEVICE name has been specified,
that is, if you enter device type numbers other than those shown in the top of
the display, following the heading "ATTACH DEVICES:."
Also appears if you try to detach the operator console by entering
X-characters for port O.
Invalid Keyboard Language: Appears if a character other than" 1" or "2" has
been entered for TRANSLATE LANGUAGE.
Duplicate Device Address: Appears if the same DEVICE ADDRESS has been
entered twice.
Duplicate Diskette Address: Appears if one of the duplicate addresses is a
diskette device address (the native user diskette address is also in the range
X'009' to X'01F').
Invalid Configuration: Appears if the "Configuration Rules and Limitations"
(listed above) have been violated.
Port 0 allows 3278 or 3279. If you specify for port 0 a device name valid for
ports 1 to 15 only, the message appears.
Only 8 Ports Effective: Appears if entries are made against any of ports 8-15
when the optional feature (display/printer adapter expansion) is not installed.
Configuration Update Complete: Appears when the system has finished processing of the configuration update specified by the operator.

4331 Processor Operating Procedures
Native User Diskette
When the diskette drive requires your attention, line 21 of the machine status area
shows either the legend DISK, or (if, at the same time, the system diskette also
requires attention) SYSDSK.
When you then invoke the mode selection display onto the screen and enter selector character "G" against "Selection," the screen picture changes to the "Native
User Diskette" display.
The "Native User Diskette" display shows the status, and allows you to control,
the direct attached diskette drive. The DEVICE STATUS displayed may be:
STARTED
NOT READY
LOAD NEXT DISKETTE
DEFECTIVE DISKETTE
STARTED indicates that the diskette device can accept commands from the
source program. NOT READY indicates that a command was issued either to a
stopped drive or to a started drive without diskette or with open cover. It can also
indicate a hardware malfunction such as a torn drive belt, a defective index pulse
sensor, or a wrong type of diskette.
Note: The READY and NOT READY indications do not immediately reflect any
manual interference; they show the state of the diskette I/O as it was when the
device was last addressed. For example, when the device is ready and you remove
the diskette, the status will still show READY until the device is addressed. Only
then will the indication change 10 NOT READY. LOAD NEXT DISKETTE
indicates that a new diskette is required.
DEFECTIVE DISKETTE indicates that machine-internal error recovery failed
and that, to recover, the diskette has to be replaced or the service representative
to be called.
ERROR CODE is a two-digit code. For detailed information, refer to IBM
4321/4331 Processor Functional Characteristics and Processor Complex
Configurator, GA33-1526.
"N" for START
"S" for STOP
"R" for RESET
The operation specified is executed when you press the ENTER key.
START
This operation is rarely required because the action of loading a
diskette and closing the cover makes the device automatically ready.
Alternatively, only the cover need be opened and then close4. The
ST ART command allows you to make the diskette ready from the
operator console, provided a diskette is mounted.
Chapter 3. Procedures
3-59
STOP
This command halts the device at the completion of the current operation and makes the device not ready. You should stop the device
prior to removing the diskette to make sure that you do not disturb
any operation in progress.
RESET
This command performs the start function as described above, and
the device is conditioned to move the access mechanism to its home
position the next time a command is received.

Model 138, for example), follow these instructions:
1. Wait until all disk jobs are finished or flip the 3340 start/stop switch to
"Stop."
2. Flip the interface A switch on the 3340 controller from "enable" to "disable."
3. Switch power off at the 3340 controller.
4. Flip the interface B switch on the 3340 controller from "disable" to "enable."
5. Switch power on at the 3340 controller and check thal the 3340 start/stop
switch is at "Start."
6. Processor B is now ready to process jobs on the switched 3340/3344s,
To reverse the string switch assignment, proceed as follows:
1. Wait until all disk jobs are finished or flip the 3340 start/stop switch to
"stop. "
2. Flip interface B switch to "disable."
3. Switch power off at the 3340 controller.
4. Flip the interface A switch to "enable" and check that the 3340 start/stop
switch is at "start."

To convert a binary number (see the table above), proceed as follows:
1. Separate the binary number by spacing it into groups of four bits each, starting from the right. If necessary, add leading zeros for leftmost group. Thus:
Binary 110110110
= 0001
1011 0110.
2. Using the first two columns of the table, convert each group of four binary
bits into hexadecimal (hex). Thus:
Binary 0001 1011 0110
= Hex 1B6.
3. Working from the right, relate bits of the hex number to the associated decimal column. Thus:
6 relates to 16 0 column, B relates to 16'
column and 1 relates to 16 2 column.
Using bits in the hex column as reference, find the associated decimal part and
add decimal parts to get the decimal total. Thus:
Hex 6
Hex B
Hex 1
( 16°
( 16 2'
( 16

Katakana Feature
When the Katakana feature is installed your console has a special keyboard
marked with Katakana characters. There are 48 data keys and four shift keys.
Data Keys
On the top of each data key up to four characters (Katakana as well as regular
alphamerics and symbols) are shown. Thus each data key allows you to enter up
to four characters, one or two of which may be blanks.
Shift Keys
There are four shift keys (see column 2 of Table). The shift keys set the keyboard
for selecting characters. Before entering data, press the appropriate shift key for
either upper left, lower left, upper right, or lower right characters. Once selected,
a shift stays in force until (1) another shift key or (2) the MODE SEL DIAG
key is pressed. Pressing this key key sets alphameric mode.
You can see which shift has been pressed by 10Qking at the status indicator on line
25 of the screen (see column 4 of Table).
Messages
When the Katakana feature is installed, messages from the operating system may
be displayed in Katakana but other messages (for example, maintenance displays)
appear in English.

Color Convergence Procedure
This procedure (Figure A-2) describes how to optimize the settings of the primary
colors (red, green and blue) displayed to produce a pure compound color. For
example, white contains all three primary colors. If convergence is wrong, you can
see traces of each color at the edges of a white character.
If the color convergence procedure is just performed with another 3279, the mes-
sage CONVERGENCE ON PORT NN is displayed.
Note: Before doing color convergence, check the date on the battery located in
the access area at the back of the 3279-2C. (The first two numbers represent the
month, the second two the year). If the battery is more than 3 years old, change it
according to the procedure in this chapter.
Color Convergence Procedure

the Battery
A battery in the access area at the back of the 3279-2C provides power to the
color convergence storage when the display is switched off. If the color convergence has to be adjusted, or if machine check indicator followed by 228 or 229 is
displayed on line 25 each time you switch on the display console, change the batiery.
Note: Each battery is marked with a date-code; the first two numbers show the
month, the second two show the year; if a battery is more than 18 months old, do
not use it.
Replacement batteries are available from IBM through your IBM marketing representative. Order only sufficient batteries for your immediate needs; batteries can
be expected to provide 3 years of normal operation, and those more than 18
months old must not be used as replacements.
The display console should be switched on while the battery is bemg replaced, if it
is switched off the full convergence procedure will be required.
To change the battery:
1. With the 3279-2C switched on open the cover of the access area at the back
of the 3279-2C.
2. Unplug the connector from the old battery and remove the battery.
Note: Return the old battery to IBM for disposal.
3. Place the new battery in the holder and replace the connector.
4. Close the cover of the access area.
5. Check operation with the new battery:
a.
Observe the displayed characters and, if necessary, perform the Convergence Procedure described in this chapter.
b. Switch power off and wait for approximately five minutes.
c.
A-8
4331 Processor Operating Procedures
Switch power on; the color convergence should be satisfactory. If the convergence is wrong, unplug the new battery and plug it in again to make
sure that the connection is good; then perform the Convergence Procedure. (If thesymptom persists, record the problem.)

publication •. Awider and more general range of terms is contained in IBM Data Processing Glossary, GC20-1699.
IBM is grateful to the American National Standards Institute
(ANSI) for permission to reprint its definitions from the American National Standard Vocabulary for Information Processing
(Copyright 1970 by American National Standards Institute,
Incorporated), which was prepared by Subcommittee X3.5 on
Terminology and Glossary of American National Standards
Committee X3. These definitions are indicated by an asterisk.
address translation. The process of changing the address of an
item of data or an instruction from its virtual address to its
machine storage address. See also dynamic address
translation.
basic control (BC) Mode. A mode in which the features of a
System/360 computing system and some System/370 features,
such as new machine instructions, are operational on a
System/370 computing system or a 4300 processor. See also
extended control (EC) mode.
CCITT. Consultative Committee on International Telegraphy
and Telephony.
control registers. A set of registers used for operating system
control of relocation, priority interruption, program event
recording, error recovery, and masking operations.
control storage. An area in a subprocessor where the microcode
is stored.
cursor. A movable marker on a video display used to indicate
the position of the next character to be entered on the screen.
DDS. DATA-PHONE Digital Service. DATA-PHONE is both
a service mark and a trademark of AT & T and the Bell System.
*dump. To copy the contents of all or part of a storage, usually
from an internal storage into an external storage.
initial microcode load. The procedure that causes the microcode
to be loaded into control storage. Abbreviated to IML.
*initial program load. The procedure that causes the initial part
of an operating system or other program to be loaded such that
the program can then proceed under its own control. Abbreviated to IPL. In the 4321/4331s this procedure is known as
"program load."
*initialize. To set counters, switches and addresses to zero or
other starting values at the beginning of, or at the prescribed
points in, a computer routine.
integrated adapter (or attachment). A device which allows I/O
devices to be attached to the system without a standard
input/output interface.
*interrupt. To stop a process in such a way that it can be
resumed.
key in. Refers to the typing of characters by means of the
alphameric keys at the keyboard. It does not include pressing
the ENTER key. See also "Enter."
machine storage. The storage where data and instructions actually reside when they are accessed by the processor and channel programs (called real storage in System/370).
main storage. All program addressable storage from which
instructions may be executed and from which data can be
loaded directly into registers. Most machine storage is used as
main storage.
microinstruction. A basic or elementary machine instruction.
Each program, each channel routine, and so on, consists of
sequences of microinstructions.
*modem. (Modulator-DEModulator.) A device that modulates
and demodulates signals transmitted over data communication
facilities.
multipoint network. A line or circuit that interconnects several
stations in a data communications system.
dynamic address translation.
1.
The change of a virtual storage address to a machine storage address during execution of an instruction.
native attachment. A part of some machines that allows I/O
devices to be attached to the processor directly instead of via
channel and control unit. (Also called integrated attachment
and integrated adapter).
See also address translation.
2.
A hardware feature that performs the translation.
EIA. Electronic Industries Association
enter. Refers in this manual to the placing of information into
the system by specifying commands, data or addresses at the
keyboard, and then pressing the ENTER key. See also "Key
I n. "
extended control (EC) mode. A mode in which all the features
of a System/370 computing system or a 4300 processor in 370
mode, including dynamic address translation, are operational.
See also basic control (Be) mode.
*online. Pertaining to equipment or devices under continual
control of the processor.
*operating system. Software that controls the execution of
computer programs and provides scheduling, debugging,
input! output control, accounting, compilation, storage assignment, data management, and related services.
processor. A device which fetches instructions from main storage, processes them, and returns the results to main storage. It
also analyzes I/O instructions and handles input/output operations and I/O interruptions.
hexadecimal. A number system that uses the equivalent of a
decimal number 16 as a base.
Glossary
X-1
program load. See "initial program load."
program status word. A doubleword in the processor storage
used to control the order in which instructions are executed,
and to hold and indicate the status of the computing system in
relation to a particular program. Abbreviated to PSW.
teleprocessing. The processing of data that is received from or
sent to remote locations by way of telecommunication lines.
trihutary station. In a centralized multipoint data communications system, this is a station, other than the control station,
that can cOllltllunicale only with the control station when
polled or selected by the control stations.
real address. The address of a location in real storage.
real storage. The storage of a computing system where data
and instructions in machine storage are made addressable to
the processor and channel programs.
service processor. A subprocessor which loads microcode, initializes the system, monitors and logs errors, and handles the
manual control operations of the system.
stand-alone program. An independent program that does not
require an operating system.
X-2
4331 Processor Operating Procedures
typamatic key. A key that repeats its function as long as it is
held down.
virtual address. An address which refers to virtual storage and
must, therefore, be translated into a machine storage address
when it is used.
virtual storage. Addressable space that appears to the user as
main storage, from which instructions and data are mapped
into machine storage. The size of virtual storage is limited by
the addressing scheme of the computing system rather than by
the actual size of machine storage.
