Emergency Procedures If people are endangered, or if equipment could be damaged, disconnect power to the system by pressing the relevant EMERGENCY POWER-OFF switch in the computer room. Electric Shock 1. If the casualty is still in contact with the electrical supply: 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. Fire Do not use water to fight a fire in electrical equipment. Use only a fire extinguisher approved for this purpose, for example one that contains carbon dioxide (C02). Follow the instructions on the extinguisher and 'call for help. Chapter 1. Emergency'Procedures 1-1 1-2 4331 Processor Operating Procedures Chapter 2. Communicating with the System This section describes the parts of the IBM 4321 or 4331 Processor that you, as an operator, will use in your work. Chapter 2. Communicating with the System 2-1 Operator Console The operator console is a device used to control the IBM 432 I or 4331 Processor. It consists of: Display Screen to provide information from the system, in the form of messages and displays. The information that you enter into the system also appears on the screen. A permanent display of the status of the IBM 4321 or 4331 Processor is shown in the lower part of the screen. Console Keyboard - • for entering commands and data into the system. Control Panel with lights and buttons for functions that cannot conveniently be handled by the keyboard and display screen. The operator console may be a 3278-2A (one-color display) or a 3279-2C (four-color display). The console does not provide printed output. The optional 3287 Model 2 printer may be used to supply printouts of messages.

Screen Layout The display screen displays numeric characters, alphabetic characters and special symbols. It is equipped with an audible alarm that alerts you to messages requiring your attention" During operation the security keylock must be in the "on" position. The fmmat of the screen is shm\<'n below. DISPLAY FORMAT 1<-----80 CHARACT!RS----->I ---------------------_.--------------20 lines 21 LINES· 5 1 ines r:hapter 2. Communicating with the System 2-3 A System Area: The system area of the screen displays messages from the operating system. It is also used when the operator communicates with the system. B Machine Status Area: This area displays information about the status of the IBM 4321 or 4331 Processor. Control Panel On the control panel are the following lights and keys that allow you to check and control basic machine functions. BASIC CHECK SYSTEM WAIT 000 POWER IN POWER PROCESS COMPLETE a a c:J ML, [!JAMP TEST EJOWER OFF --- --- --- 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. Chapter 2. Communicating with the System 2-5 C I Console Keyboard At the console keyboard you enter commands and data il1to the system. The keyboard has the following layout: CHG CNCL OPt (PA2) START STOP ERAS)E INPUT t ~ ~ ~ PAGE·:tPAGEI .--"l1li "l1li -~ [:.:::!:!:::::::~. Only active when AL T key is pressed at the same time C::3 Typamatire key 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. €> The cursor is a light-marker on the screen to be entered will appear. • that~indicates \vhere When a character is entered, it appears just above the. cursor: The cursor is automatically positioned ready for the • 2-6 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 2-8 4331 Processor Operating Procedures a color convergence test, see Note following description of CHG DPLY. CHGDPLY: ~ ~ 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. The SP M/O function of this key is for service personnel only. REQ I Comm REQ: ~~illil~ . :~~unction of the REQ (request) key depends upon the command set being • When the 1052 command set is being used, the keyboard is normally locked. It is freed when the system executes a read inquiry command which is invoked by pressing the REQ key. • When the 3270 command set is being used, the REQ key requests an Attention Interrupt. The COMM REQ (communication request) function of this key is for service personnel op.ly. Chapter 2. Communicating with the System 2-9 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. See also Problem Determination Guide located in the keyboard. RESET Start: I START 2-10 I Press START to start the processor. Instructions are processed in two modes: • Instructio:p step mode - one instruction is processed each time START is pressed (See "Instruction Step" in Chapter 3.) • Continuous processing, for example when START is pressed after a normal pause in system operation. 4331 Processor Operating Procedures Stop: ISTO~ Press STOP to stop program execution. The system stops when processing of the current instruction and any 1/0 operation;n progress is completed and after waiting interrupts have been serviced. Insert Mode: Use this key before you insert charact¢rs fnto existing information displayed on the screen.

Enter: When you press ENTER, the data that YV'U· have typed into the display is accepted by the system. Until you press ENTER, the data can be changed. 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 Chapter 2. Communicating with the System 2-11 the requested action. The following system keys are never locked or inhibited: STOP INTR MODESEL DIAG 2-12 4331 Processor Operating Procedures Machine Status Display The last five lines on the display screen show the status of the system.

System Diskette The system diskette provides services for control, testing, error diagnosis and logging. There are two diskettes: • • Control Diskette Diagnostic Diskette both containing information vital to the functioning of the system. To safeguard this information, avoid the following: • • Rough handling of the diskette. Handwriting on the diskette (do not write on the diskette cover with the diskette inside it). Pressure on any part of the diskette. Strong, direct sunlight on the diskette. Attempts to clean the diskette in any way. Exposing the diskette to magnetic fields (Keep it away from metal objects). Touching exposed surfaces of the diskette. Inform the service representative if the diskette is damaged in any way. Under normal conditions the system diskette remains in the drive unit and need not be handled. 2-20 4331 Processor Operating Procedures Custolner Set Up (CSU) for Displays and Printers The IBM 4321 or 4331 Processor has a customer access area to enable the customer to connect CSU equipment such as display units, matrix printers, and line printers. The customer access area is located at the bottom left-hand side of the processor opposite the system diskette. System Diskette Customer Access Area 4321 or 4331 (Top View) Connector for the coaxial cable must be a Bendix 3022-3 or equivalent. Switch power off. Run the cable under the bracket and plug the connector into the appropriate receptacle as shown. Chapter 2. Communicating with the System 2-21 (Operator Console) When you have connected the device, you have to provide the system. ",vith information on this connection. The procedure "Native Displays and Printers" in Chapter 3 of this manual tells you how to do this. Disconnecting To disconnect CSU equipment, switch power off and pull out the Bendix or equivalent connector. Problem Determination If physical installation and the procedure "Native Displays and Printers" have been carried out, and the line printer does not operate, check if "intervention required" is indicated. The indication "intervention required" varies from one . operating system to the other. The following conditions cause "intervention required" to l?e indicated when the line printer is in the ready state: • 2-22 Open coax cable Line printer not logically connected 4331 Processor Operating Procedures CAUSE Open (the face both ters coax cable CPU interlight at line prinis off) Line printer not logically connected ACTION Switch power off. Connect the coax cable to the defined port, or repair the coax cable For 3262: Press the Test key. For 3289: Press the Reset switch. Or, for both line printers: Invoke "program Reset", or re-IML. If this action is unsuccessful, call the service representative. Chapter 2. Communicating with the System 2-23 2.;.24 4331 Processor Operating Procedures Chapter 3. Procedures This section describes manual operations on the IBM 4321 or 4331 Processor. The information is divided into procedures. Chapter 3. Procedures 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. 3-2 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. POWER IN PROCESS light comes on. Wait 30 seconds. No Turn to "Operator's Problem Determination. " Proceed to 1M L Chapter 3. Procedures 3-3 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. 3-4 4331 Processor Operating Procedures Loading the Microcode (IML) . The microcode controls processor operations and must be loaded into control storage before any other program can be loaded. All microcode is contained on the system diskette and is loaded when you switch POWER ON or press the IML key on the control panel. Power - on Complete Press 1M L key. Exchange the diskette for the correct one. Yes Go to section "Operator's Problem Determination" in this manual. No Note: PROG RAM LOAD display on screen Do not press any keyboard keys at the console while IML is in progress. Chapter 3. Procedures 3-5 Initial Program Load (IPL) The initial program load (IPL) procedure causes the operating system to be loaded. The IPL procedure can also be used for loading stand-alone programs. If this is not the first IPL since power on, you get the program load display by: • Pressing MODE SEL • Keying in L • Pressing ENTE R The specifications from the last IPL appear in the display. A description of entries into IPL display is explained under "Program Load Display" in this manual. LOAD display on screen on line 21 Ensure the device to be used to load the program is ready. Prepare to reload with a correct program. No Press ENTER. Key - in specifications. Press ENTE R. If the specifications are to remain the same; if not, key in new specifications and press ENTE R. Yes LOAD appears on line 21 from the moment ENTER is pressed, until a valid PSW is loaded. Proceed with usual operating procedures. Check for normal states across entire system. Assign devices and start running jobs. 3-6 4331 Processor Operating Procedures In the case of an unusual situation such as BASIC CHECK light on, or CHECK stop on line 21 turn to "Operator's Problem Determination." • If IPL repeated and is unsuccessful, press CNCL to allow for logging. If continuous logging occurs, repeat IML and continue. If the problem occurs again, call the CEo Mode Selection There are two modes of operation for the 4321 or 4331 Processor: 1. System operation mode, in which instructions and I/O operations are executed under program control. 2. Manual operation mode. Mode selection enables you to stop or suspend the system operation mode and enter the manual operation mode. The manual operations described in this section allow you to display and change certain control information and data. These operations are listed below and the associated operating procedures are given on the following pages. Column 1 in the list gives the names of the manual operations; column 2 shows the selector character used to call up the display. Columns 3 and 4 show the manual operations that apply to 370 and VSE.

For the manual operations listed on the left of the screen. entry is now complete. The mode is operational. For the manual operations listed on the right of the screen, the above procedure calls up a separate display in which additional selection characters may be entered. The following pages describe how to use these displays. Errors Made During Mode Selection When you have pressed ENTER, the system checks your entries and displays the following messages if it detects an error: Invalid Character: the first character entered is not one of the selector characters shown in the display. The "MODE SELECTION" display remains on the screen and the cursor indicates the error. To complete selection enter the correct selector character. Incomplete Entry: No character was entered, or the input was incomplete. To correct the error, enter the complete specification. Chapter 3. Procedures 3-9 Fast Mode Selection "Fast Mode Selection" enables you to type in all specifications for a mode at once without going through the selection procedure picture by picture. 1. Press MODE SEL. The "mode selection" display will appear. 2. Type in the mode selector character (col. 1 in list). 3. Type in your mode specifications (one character from each group in col. 2 plus an address if required). 4. Press ENTER. A quick-reference list of the specifications is given below.

Chapter 3. Procedures 3-11 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. *STORAGE ADDRESS COMPARE* FUNCTION COMPARE TYPE N NORMAL S STOP Y SYNC A ANY C INSiRUCTION COUNT D DATA STORE I I/O DATA STORAGE ADDRESS 'O-FFFFFF ADDRESS: To select and set "address compare": 1. Press MODE SEL to call up the "mode selection display" and enter an A after 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 3-14 4331 Processor Operating Procedures Check Control The "check control" mode allows you to preset the system's response to machine checks. The current check control mode is shown in line 22 of the machine status area. "'CHECK CONTROL'" N NORMAL S HARDSTOP SELECTION: MACHINE STATUS DTSPLAY (LINES 21 - 25) To select "check control" mode: 1. Type K into the "mode selection" display after the word SELECTION. 2. Press ENTER. The screen picture changes to the "check control" display (see example above). 3. Enter one of the following selector characters into the display: N (N ormal) This code causes the previously selected check control 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). Chapter 3. Procedures 3-15 Error Message: Invalid Character indicates a selector cha.racter other than "N" or "S." .3-16 433 JProcessor Operating Procedures Display / Alter "Display / Alter" mode allows you to display and/or alter values in the processor. The values that you can display and alter are listed as options shown in the example below.

To change data in a selected option: 1. Position the cursor in the alter field and under the character to be changed, that is, one line below the character displayed. 2. Type in the new character. It will appear underneath the current character which continues to be displayed. 3. Press ENTER. The new character moves up from the alter field into the display field and replaces the old character. At the same time it is stored in the 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. Incomplete Entry appears and the cursor is set below the next character to be specified if, during fast selection, you entered incomplete specifications.

When you press ENTER, the machine stops and the PSW is displayed in binary notation, except for the instruction address, which appears in hexadecimal notation. The logical meaning of the data that appears in the "current PSW" display depends on whether your machine is in VSE or 370 mode, and also on whether it is in Basic Control (BC) or Extended Control (EC) mode. The control mode currently in effect for your machine, 370 or VSE, is shown in line 21 of the machine status area, and the EC or BC mode is distinguished by the E-bit in the PSW being one for EC mode, 0 for BC mode. The contents of each bit position in the PSW are represented as binary 1 or 0 ("B" in the example above).

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. Chapter 3.

When all updating is finished, press ENTER. When you intend to finish the procedure without changing anything press PF3. 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. Chapter 3. Procedures 3-37 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 when 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. 3-38 4331 Processor Operating Procedures Binary Synchronous Communication (BSC) Lines This display allows you to change the values of certain options for the telecommunication lines under BSC control.

When all updating is finished, press ENTER. When you intend to finish the procedure without changing anything press PF3. The following describes the BSC 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 Signal 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 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). Tributary Station Address: The tributary station addresses appear only if your installation includes BSC lines and you have entered B in the CA-Customer Manual Ops display. This selection brings the following display to the screen: Chapter 3. Procedures 3-41 *** TRIBUTARY STATION ADDRESS (ES) FOR BSC LINES *** ENTER TRIBUTARY STATION ADDRESS (ES) IN HEX: LINE L.INE LINE LINE LINE 3D 31 35 36 37 ** 40xx * ** 40xx * ** 40xx * ** 40xx * ** 40xx * 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. Chapter 3. Procedures 3-43 Instruction Step Instruction step mode allows you to direct the processor to execute only one instruction with each depression of the START key. The changes in data that occur for each instruction executed are shown on the screen so that you can follow them. This mode is set from the mode selection display. To select instruction step mode: 1. Type I into the "Mode Selection" display next to SELECTION. 2. Press ENTER. Line 22 of the machine status area indicates when instruction step mode is in effect. Instruction step mode remains in effect even if other modes are subsequently selected, such as "Display/Alter" mode. To terminate "Instruction Step" mode see "Reset I-step." ( \ \ 3-44 4331 Processor Operating Procedures Interval TinIer This display enables you to start or stop the interval timer. The state of the interval timer is shown in line 21 of the machine status area. "'INTERVAL TIMER'" N ON N OFF SELECTION: To select the "Interval Timer" display: 1. Type J into the mode selection display next to SELECTION. 2. Press ENTER. Type one of the following into the display next to SELECTION: N - Turn timer on. F - Turn timer off. The interval timer is started automatically at IML time. Chapter 3. Procedures 3-45 Machine Save The "Machine Save" operation enables you to make a record of the current state of the processor (VSE mode only). A save operation is especially recommended prior to loading any dump programs or other diagnostic means that use internal facilities (such other diagnostic means that use internal facilities (such as registers). The save operation preserves the processor state as it was when the error occurred. To specify machine save: 1. Type S into the "Mode Selection" display next to SELECTION. 2. Press ENTER. When machine save is specified, the following actions occur in the system: • The processor stops. The contents of page 0, that is, the 2048 bytes at addresses 0 to 2047, and all registers and timers are saved in internal storage. When a save operation has been completed successfully, the save indicator in the machine status area is turned on. A reset, IPL or power off during "machine save" terminates the operation. 3-46 433] Processor Operating Procedures Program Load The "Program Load" display enables you to load the operating system and the application programs to be run on your installation. This operation is usually known as "initial program load" (IPL). The display appears automatically when IML has been completed successfully. *PROGRAM LOAD* CHANNEL 0-6 '* *- MACHINE MODE V VSE 3 370 * * NUMBER OF EMU BUFFERS 0-8 * * CONTROL UNIT O-F * *- VSE STORAGE SIZE 2=2MB C=12MB 4=4MB M=16MB 8=8MB R=REAL * * EMULATED DEVICE R 2311 S 2314 T 3330 u 3340 * * DEVICE O-F * P PROGRAM C CLEAR * *- 1052 MODE P=PRINT N=NO PRINT F=OFF * * FIRST HOST ADDRESS IN HEX * NUMBER OF 3340 BUFFERS 1-8 * * EMULATION ONLY MODE Y YES N NO * *- Note: The following legends appear on the screen only when the corresponding compatibility features are installed: • 1052 MODE NUMBER OF 3340 BUFFERS NUMBER OF EMU BUFFERS EMULATED DEVICE FIRST HOST ADDRESS EMULATION ONLY MODE To select the "program load" display: 1. Type L into the "mode selection" display after SELECTION. 2. Press ENTER. The program load display appears on the screen, showing the specification entered for the previous load operation. If you wish to repeat this specification, press ENTER and proceed. If you wish to perform a different load operation, specify as follows: 1. Enter the address of the device from which you want to load your programs in the CHANNEL, CONTROL UNIT, and DEVICE fields. Chapter 3. Procedures 3-47 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). See "Native Displays and Printers" for additional information. Chapter 3. Procedures 3-49 Clear Reset The "Clear Reset" operation enables you to reset the entire system and clears the storage. This operation is initiated from the mode selection display. To set "Clear Reset": 1. Type C into the "Mode Selection" display. 2. Press ENTER. When "Clear Reset" is entered, the current operation (if any), is halted. Any pending interruption conditions or machine checks are cleared, and the CPU stops. The following system resources also stop: • • All channels including their control units and attached devices All adapters including attached devices The RESERVE status of 3340s or 3370s is reset. The physical switch on the 3340 or 3370 is set to NEUTRAL if it was occupied by the 432] or 4331 Processor. "Clear Reset" resets the channels and the CPU and initializes the control registers. It also clears to zero the values of the following: • • • • • Main storage Current PSW CPU timer Clock comparator General registers Floating point registers Keys in main storage Page description All error counters and usage counters in directly-attached disk drives. The TOD clock is not altered and its parity remains unchanged. The mode selection display remains on the screen and, when processor reset has been completed, RESET COMPLETE appears. 3...;50 4331 Processor Operating Procedures Reset I-Step "Reset I-Stcp" has no display. It is performed from the "Mode Selection" display. To set "Reset I-Step": 1. Type N into the "Mode Selection" display after SELECTION. 2. Press ENTER. When "Reset I-Step" has been set, the instruction step indicator in line 22 of the machine status area is turned off and the screen is returned to the operating system. To continue processing, press START. Chapter 3. Procedures 3':;51 Program Reset The "Program Reset" operation enables you to reset certain system resources without resetting storage and vital control parameters in registers. The operation is performed from the mode selection display. To specify "Program Reset": 1. Type P into the "mode selection" display next to SELECTION. 2. Press ENTER. When "Program Reset" is entered, execution of the current instruction (if any) is halted, any pending interruption conditions are cleared, and the CPU stops. The following system resources also stop: • All channels including control units and attached devices All adapters including attached devices The RESERVE status of 3340s or 3370s is reset. The physical switch on the 3340 or 3370 is set to NEUTRAL if it was occupied by the 4321 or 4331 Processor. Program Reset resets the channels and the CPU, but it does not affect the values of the following: Current PSW CPU timer Clock comparator General registers Floating point registers Control registers Main storage Keys in main storage Page description Reset Complete appears on the screen when processor reset has been completed. Program reset should not be used indiscriminately because it leaves the registers and the storage loaded with values from previous activities and this may not be suited for a restart. Only program reset should be used prior to loading a stand-alone dump program. 3-52 433;1 :Prpcessof,Opep;lting Procedures Restart The "Restart". operation is used to restart processing from a logical point defined by the operating system. This operation is specified from the mode selection display. To specify "Restart": 1. Type R into the "Mode Selection" display next to the word SELECTION. 2. Press ENTER. When "Restart" has been entered, the system takes control of the screen. If the 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. Chapter 3. Procedures 3-53 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." Chapter 3. Procedures 3-55 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 Operator Console Facility, GA33-1545.) 2.

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 3-57 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. 3-58 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. * DEVICE STATUS: DEFECTIVE DISKETTE NATIVE USER DISKETTE NOT READY * LOAD NEXT DISKETTE ERROR CODE: xx DEVICE CONTROL: N START S STOP R RESET *- * The following message is displayed when Invalid Character 3-60 4331 Processor Operating Procedures ~n invalid character is entered: Diskette Device Address The "Diskette Device Address" display permits changing the device address of the diskette I/O.

Reference Information 5 -7 Manual Calling on Integrated Modem WT Switched Line with Auto Answer Connection Sequence 1/ the line is the calling side: 1. Disable the line (if not done before (see Note 1)). 2. Lift the handset and dial the number of the station to be called. 3. Ensure that the called station is in data mode. Switching to data mode is done by the operator (if manual answering station) or automatically after completing the answer tone (if auto answering station, see Note 2). 4. Enable the line immediately (see Notes 3 and 4 ). 5. Replace the handset. Note 1: Manual dialing from the enabled line is not possible. Note 2: In certain countries, the answer tone is not used for mode switching. In this case, consult the TP specialist. Note 3: If the line is enabled during receiving the answer tone, the result may be unpredictable. Note 4: Don't make noise after the called station enters data mode and before the line is enabled. Otherwise, it will be recognized as receive data at the called station. If the line is the called side: Enable the line before or during being called (but never lift the handset) (see Notes 1 and 2). Note 1: If the handset is lifted before or during being called the result may be unpredictable. Note 2: For use of the handset for telephone conversation disable the line first. Disconnection Sequence In either case where the line is the calling side or the called side, disable the line, if not done by the software automatically (see Note). Note: 5,;.8 4331 Processor Operating Procedures Otherwise, the telephone charge continues to accumulate (if the calling station) or the line stays busy and cannot accept any other calls (if the called station). 3340 String Switch Since the 3340 string switch is not program-controlled, switching must be done by the operator. The 3340 string must always be assigned (switched) to one processor at a time. To switch from processor A (a 4331, for example) to processor B (a System/370 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." 5. Switch power on at the 3340 controller. "" 6.

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 column) decimal 6 column) decimal 176 column) decimal 256 decimal 438 5-10 4331 Processor Operating Procedures Hex lB6 Binary 110110110 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 Make the 3279 - 2C ready. ..:.::.://I////:% IA is indicated in line 25.

A-7 Cba~ 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.
