INTRODUCTION

MAINTENANCE STRATEGY T::DAX maintenance is based on the following T::DAX features:

Problem detection and reporting with built-in diagnostics

Automatic generation of appropriate alarms

Automatic or manual switching to backup units

Replacement of defective units without service interruption

Work around to clear trouble

In addition, T::DAX includes visual indicators to support on-site maintenance. These include blown fuse indications and out-of-service module indications. Visual indicators enable on-site personnel to quickly locate a defective unit for quick replacement.

ROUTINE MAINTENANCE T::DAX is engineered so that very little routine maintenance is required. Routine maintenance consists of:

Cleaning the tape heads in the tape drive

Replacing fan filters

Changing the tape on the tape drive

Note: The frequency of these actions is site-specific since it is determined by the frequency of T::DAX use. Contact your system administrator for recommended schedules for the maintenance activities.

1.3.

1.4.

T::DAX DIAGNOSTICS AND TROUBLE REPORTING T::DAX diagnostics run automatically without interfering with normal operations. In most cases, the diagnostics can isolate the problem to the replaceable module. If the specific module cannot be identified, T::DAX reports suspected trouble sources to aid manual troubleshooting. When the diagnostics detect a problem, T::DAX reports the problem and suspected source. If service will not be affected, T::DAX automatically takes the suspected unit out of service and, if necessary, activates the protection or duplex unit. The defective unit can then be replaced without affecting normal T::DAX operations. If the replacement unit passes diagnostics, T::DAX automatically puts the unit in service. You can also run diagnostics on an out-of-service unit on command. T::DAX runs the diagnostics and reports the results.

ALARM GENERATION AND CONTROL T::DAX generates the following types of alarms:

Critical alarms for failures causing a loss of service on more than 5 DS1, E1, VT1.5, VT2, VC11 or VC12 cross-connects.

Major alarms for failures causing a loss of service on any single port, tributary or cross-connect.

Major processor alarms for control system failures that disable the control capability.

Minor alarm for failures that do not affect service.

T::DAX reports these alarms in the following ways:

Alarm indicators on the TAIC front panel

Alarm messages are sent over the CIT and DTM interface links

Alarm indications are sent to central office audible and visual alarm systems and E-telemetry systems.

An audible cutoff (ACO) feature is included for silencing audible alarms and switching visual alarm indicators to an "alarm acknowledged" state. T::DAX includes a front-panel mounted ACO switch and connections for remote ACO control.

1.6.

MAINTENANCE COMMANDS The T::DAX command set includes the following types of maintenance commands:

RTRV-COND-EQPT command displays the current condition of the equipment unit.

RMV-EQPT command removes the specified unit from service and places it in the maintenance state. This command must be executed before running diagnostics or removal of unit.

DGN-EQPT command runs a diagnostics routine on the specified equipment.

RST-EQPT command restores a specified unit to service, switching it from the maintenance state to the in-service state.

AUTOMATIC SWITCHING TO BACKUP UNITS T::DAX includes protection or duplex modules for T::DAX equipment.

• ISU and TSU modules have one “redundant” unit used as protection for all other TSU and ISU modules.

• E3/DS3/STS1 interface cards have one protection card per shelf. • SM4/LHR/CHR/THR3/EHR3/OHR3 cards work in a 1+1 equipment and facility

protection configuration. • SMX/MSMX cards have a 1:3 redundancy protection scheme. • Each pair of IHR/MHR/LHR/CHR and MIU cards has a protection pair. • Each shelf contains two load sharing power supply units (xPSU) that are both active

during normal operation, and a single unit powers the shelf if the other fails. The following are all “duplex” modules, with one unit active and one stand-by:

• Power Supply Units (xPSU) – load sharing • Admin shelf Control Processors (xACP) • Control Units (xCU) • Narrowband Matrix Units (NBX) • Clock Distribution Units (CDU) • Clock Buffer Units (CBU) • Synchronous Multiplexer and Clock unit (SMC) • Admin Communication Control unit (ACC) • PCU Bus (cables)



1.7.

1.8.

1.9.

MODULE REPLACEMENT The primary maintenance strategy for T::DAX is module replacement. In all cases (except for DS1/E1 cards), modules can easily be replaced without affecting operation of T::DAX. Module replacement consists of the following steps:

1. Check that the module is in maintenance state and out-of-service. 2. Physically remove the module from the system. 3. Install a replacement module in the system. 4. Return the module to its normal in-service state.

With the diagnostics feature turned on, the state changes are done automatically if the change is not service affecting. This makes module replacement quick and easy.

SYSTEM RECOVERY System recovery is an initialization of processor-equipped T::DAX modules. You can perform the following types of system recovery:

A warm start is initialization with a “valid” database. A warm start initializes individual modules, such as the ACP, AMU, CDU, DSU, SCU, TCU, MCU, ECU, OCU, RCU, NCU or TPDR. A warm start saves cross-connect and PM data. The database is valid after the following command is performed: INIT-SYS::AMU:ctag::0; A cold start is an initialization with a “non-valid” database. A cold start is

performed when the T::DAX is powered up, or by plugging out the AMU, disconnecting the battery jumper and plugging out the two ACPs.

TECHNICAL SUPPORT Enavis Networks Ltd. offers a full range of support services for T::DAX, including:

Remote trouble diagnosis

Software and documentation updates

Telephone assistance, including 24-hour availability of technical personnel.

Enavis Networks Ltd. offers a range of service plans to T::DAX customers. Contact your system administrator for details about specific product support services available.



2. COMMON OPERATING PROCEDURES

2.1. TASK INDEX Use the following index to find your task. If your task is not listed in the following index, refer to the Table of Contents at the beginning of this manual to locate the procedure. Note: The procedures in this section are for TL1 mode operation.

If Your Task Is To: See Section:

Log into T::DAX 2.2

Log out of T::DAX 2.3

Cancel an entered command 2.4

Change your password 2.5



2.2. LOG INTO T::DAX Note: If your T::DAX is part of an Operations Support System, use the login instructions in your OSS manuals. The instructions in the following paragraphs are not for OSS applications. To operate T::DAX you must establish communications with T::DAX and log in. You can use a variety of user/system interface (USI) devices to communicate with T::DAX. Since, in most cases, the USI device is a video terminal, this section uses the term "video terminal" instead of "USI device". You can use any VT100-compatible video terminal with T::DAX. During normal operation, you communicate with T::DAX through a communications port on the T::DAX Communication Processor Module (CPR). The CPR contains four asynchronous RS-232C ports, one X.25 port and one TCP/IP port. The RS-232C ports provide direct access or connect to modems at the T::DAX site. How you connect your video terminal to T::DAX depends on the configuration of your system. T::DAX supports the following:

Direct RS-232 cable connections

Dial-up connections using modems

Private line connections

X.25 connection

TCP/IP connection

The procedure for establishing a connection to T::DAX depends on the equipment and connection types used in your system. Contact your system administrator if you need connection instructions. The Admin shelf Interface and Control unit (AIC/TAIC) contain a Craft Interface Terminal (CIT) connector on the front panel and a DTM port (DTM-1) on the rear for emergency operation of T::DAX by trained maintenance personnel. However, the terminal can be used by local craft for normal operation of T::DAX. The T::DAX Maintenance Manual contains instructions for using the terminal with T::DAX. To operate T::DAX, you must log-in with your user ID and password. Your system administrator assigns user IDs and passwords. If you do not know your user ID or password, contact your system administrator. Use the following procedure to log-into T::DAX.


Cat. No. 7979-71080-22 T::DAX Maintenance Manual Issue 3, June 2003 Step Logging into T::DAX

1 Establish communication with T::DAX. (The procedure for this depends on the configuration of your system.)

2 When the Admin shelf powers up, after a cold reset, the Login is allowed from the CIT and DTM-1 ports only. Only after the first Login the communication with the CPR's ports, DTM-A-1 through DTM-A-4, is allowed. After the Login, the Login screen will appear as follows: NOTICE: This is a private computer system. Unauthorized use or access may lead to prosecution.

UID: = User Identification PID: = Password DATE: = Date (format YY-MM-DD) – optional TIME: = Time of Day (format HH-MM) – optional

Contact your system administrator to obtain your UID and PID. After entering the proper data in the above fields, T::DAX will automatically revert to TL1 mode of operation. If this is the first time the PID is being used, T::DAX will force the user to change the PID before proceeding. This is to ensure password privacy.



2.3. LOG OUT OF T::DAX You must log-out when you are finished operating T::DAX. This terminates your user session and clears the port for use by other T::DAX operators. Note: T::DAX has an inactivity log-out feature that keeps track of periods of no activity at your terminal. T::DAX uses this feature to make sure you do not tie up a port by forgetting to log off. If the period of inactivity exceeds a preset time-out, T::DAX automatically logs you off. The time-out period can be set for up to 60 minutes. The inactivity log-out re can also be turned off. For information about time-out settings, contact your system administrator.

Step Logging out of T::DAX 1 To log out of T::DAX, enter the following command:

CANC-USER:[tid]:[uid]:ctag; uid - your user identification code. It must match the uid used in the login. A COMPLD message should be displayed, verifying successful log-out. If the COMPLD message does not appear, repeat the log-out procedure or contact your system administrator for additional instructions. If you are connected to the CPR through a modem, the system will automatically hang up (disconnect) the line. If you are connected through a direct connection or private line the log out will cause the log in screen to reappear.



2.4. CANCEL AN ENTERED COMMAND If you have entered a command and you wish to cancel it, you can stop the command. If you cancel the command, T::DAX does the following:

If T::DAX has not begun processing the command, T::DAX does not process the command.

If T::DAX has begun processing the command:

− For RTRV commands, the retrieval stops immediately. Data already retrieved is displayed.

− For commands with multiple AIDs, the requested action is not done on AIDs that have not been processed.

− For all other commands, the command cannot be canceled after T::DAX has begun processing it. T::DAX sends the SCNA (command not aborted) error code.

Step Canceling an Entered Command 1 To cancel an in-process command, enter the following:

ABT-CMD:[tid]::ctag::cmdctag; cmdctag - correlation tag that was entered with the command you want to cancel. The null string is valid here, to allow abortion of a command that was entered without a correlation tag. A COMPLD message should be displayed, verifying successful cancellation of the entered command. If the COMPLD message does not appear, T::DAX sends a DENY message with one of the following error codes: SCNF - T::DAX did not find a command with the cmdctag you entered.

SCNA - T::DAX could not abort the command.



2.5. CHANGE PASSWORD You should change your password at intervals recommended by your system administrator. (User passwords are also referred to as private identifiers.) Use the following procedure to change your password. The system contains a built-in password-aging feature (PAGE) that will force you to change your PID if it has not been changed during the PAGE interval. Note: This procedure is not for setting the CIT port password. This procedure applies only to passwords assigned to users.

Step Changing Your Password 1 Note: You must already be logged into T::DAX to change your password.

The next time you log in, you must use your new password. To change your password, enter: ED-SECU-PID:[tid]:uid:ctag::oldpid,newpid; uid - your user ID. oldpid - your current password. newpid - your new password (effective the next time you log-into T::DAX). After changing your password, you may want to log-out and log back in to verify your new password.

7 Label the tape: DATABASE, system id, date and time.



3.2.2. Backup Using FTP T::DAX supports File Transfer Protocol (FTP) to copy program, data, log and PM files from the T::DAX hard disk (DSU) to a remote server, and to copy program and data files from a remote server to the T::DAX hard disk (DSU). Use the following procedure to perform the File Transfer Protocol.

Step Backing-Up Using FTP

1 The FTP user in the T::DAX can to be define by using the command: SET-FTP-USER:::ctag::”uid”,”pid”; After the ctag, there are two colons and then in quotes the FTP username, a comma, and the password in quotes. This is the how the T::DAX will login to the FTP server Example: SET-FTP-USER:::ctag::”tdaxFtp”,”TDAX*3”;

2 The FTP is done in local restoration mode. To enter the local restoration mode use the command: STA-LOCL-RST:::ctag;

3 To copy files from the T::DAX disk, use the command: CPY-MEM::FROMMEM=SEC,TOMEM=”<destination_ip_address>” :ctag::<memusage>:NAME=name,RUSURE=Y; <destination_ip_address> - Must be in quotes and must be the address of the FTP server that you want to transfer the information to. <memusage> - Can be DATA, NBDATA, LOG, PM, PGM NAME – The directory name.

4 To copy files from the FTP server to the T::DAX disk, use the following command: CPY-MEM::FROMMEM=”<destination_ip_address>”, TOMEM=SEC:ctag::<memusage>:NAME=name,RUSURE=Y;

5 To exit the local restoration mode, use the command: EXIT-LOCL-RST:::ctag;


Cat. No. 7979-71080-22 T::DAX Maintenance Manual Issue 3, June 2003 3.2.3. Clean the Tape Heads in the Tape Drive Clean the tape heads yearly. For this procedure you need the following kit:

the filter from the shelf.

2 Clean the filter with compressed air or water and let dry.

3 Replace the fan filter in its place with the clips on its sides.



3.3. TROUBLESHOOTING

3.3.1.

Troubleshooting is simple with T::DAX’s built-in diagnostics, automatic trouble reporting, and module indicators. There are several different ways to troubleshoot T::DAX. You can troubleshoot in response to any of the following:

Alarm or event messages

Module indicators

Blown fuse indications

Automatic and manual diagnostic reports

Work around to clear trouble.

Troubleshooting procedures for each of these methods are provided in this section.

Task Index Use the following index to find your task. Note: Except for troubleshooting fuses and loss of power indications, you must be logged onto T::DAX before using the procedures in the following index. If you need information about logging on, refer to Section 1, Common Operating Procedures.


Troubleshoot alarm or event messages (REPT ALM or REPT EVT)

3.3.2

Troubleshoot module indicators 3.3.3

Troubleshoot blown fuse and loss of power indicators

3.3.4

Test hardware (run diagnostics) 3.3.5



3.3.2. Troubleshooting Alarm or Event Messages T::DAX generates alarm or event messages when it detects an equipment, cross-connect or facility problem. The messages are displayed on terminals of users logged into T::DAX. The messages are also sent to the printers (if a printer is connected to T::DAX) and stored on the log file on the hard disk (if activated). The log file can be viewed on the terminal or printed. The log interval can be set by a software command to store for up to 30 days. These messages alert you to the possible need for corrective action. They contain information that helps you locate the problem that caused the alarm. Alarm messages also activate central office alarms that are visually shown on the AIC on the Admin shelf, on the CO alarm system and a remote alarm system through dry contact relays. Alarm messages begin with REPT ALM and identify problems that need immediate attention. Event messages begin with REPT EVT and identify problems that do not cause alarms but may require corrective action. When an alarm or event is cleared, T::DAX reports the clearing with another REPT ALM or EVT message. Additional important information is displayed in the “free text” field of the alarm report. This text appears only in the Alarm/Event report and not in the response to “RTRV-ALM” command. In order to see this text, retrieve the LOG file. Use the following procedure to troubleshoot a problem reported by an alarm or event message.

Step Troubleshooting an Equipment Alarm or Event Message 1 Check the message to determine if an equipment, facility, or cross-connect

failure occurred: • REPT-ALM/EVT-EQPT is an equipment alarm or event. Continue with

step 2. • REPT-ALM-xx (where xx = E1, E2, E3, T1, T2, T3, VT1, VT2, STS1,

STS3c, OC3, VC11, VC12, VC3, VC4, STM1, OC12 or STM4) is a facility alarm. The alarm is not due to T::DAX equipment failure. Facility trouble-shooting is required. Refer to the facility maintenance instructions in the T::DAX Operation and Administration Manual.

2 Check the SRVEFF (Service Effect) field in the message for one of the following indications: SA - service-affecting NSA - not service-affecting

If the alarm is service affecting, immediate action is required.



Step Troubleshooting an Equipment Alarm or Event Message 3 Check entries in the following fields to determine the equipment associated with

the message and the status of automatic diagnostics. • The aid (access identifier) field at the beginning of the third line of the

message will tell you what type of equipment is involved. • The TBLISLT (trouble isolation) field at the end of the message. ISO = Isolated, the aid is a replaceable unit.

NIPSS = Not isolated, all diagnostics passed. The aid reports suspected units. NIMAN = Not isolated. Isolation must be performed manually. Suspected units are identified in the aid. DGN = Automatic diagnostics are in progress. Wait for a separate message with diagnostics results. No entry – Trouble isolation by T::DAX is not applicable to the alarm condition.

4 Check the message CONDTYPE = field and take corrective action listed in Table 3-1. (If corrective action clears the alarm or event, T::DAX generates an alarm or event message. The message includes the AID of the associated equipment and NTFCNCDE=CL.) The bay and shelf of the faulty unit are reported in the alarm message.

5 Verify the current status of the alarm or event by entering: RTRV-COND-EQPT:[tid]:aid:ctag; If the response is 0 RECORDS RETRIEVED, corrective action cleared the alarm or event. If the response indicates an alarm condition, corrective action did not clear the alarm or event. Repeat steps 4 and 5 for each corrective action listed in Table 3-1 for the CONDTYPE entry. If all listed corrective actions have been done and the alarm or event is not cleared, technical assistance is required. Contact your system administrator or Enavis Networks Technical Support for further instructions.

3.3.5. Test Hardware (Run Diagnostics) T::DAX includes a diagnostics feature that can detect hardware problems. T::DAX is programmed to automatically run diagnostics periodically. You can also run diagnostics on demand. T::DAX tests the specified equipment and reports the results. The procedure for replacing specific units is presented in the following section 3.3. The diagnostics are run on each unit during these procedures.

Step Testing Hardware with Diagnostics 1 To run diagnostics, the equipment to be tested must be in a maintenance state.

To display the current state of the equipment, enter: RTRV-COND-EQPT:[tid]:aid:ctag; Check the response to determine whether the equipment is in or out of service. Use the following example response as a guide to locate the equipment state in the response. <cr><lf><lf> sid YY-MM-DD HH:MM:SS <cr><lf> M ctag RTRV <cr><lf> “[aid],[aidtype]:[ntfcncde],typerep [,typerepleft][,typerepright] [srveff],[proteqpt]”<cr><lf>; Refer to Appendix B, T::DAX I/O Messages for ntfcncde typerep, srveff and proteqpt definitions.

2 If the equipment is In-Service (IS), place it in a Maintenance (MT) state by using the following command: RMV-EQPT:[tid]:aid:ctag::[mode]:[INCL=incl],[RUSURE=rusure]; mode - specifies how the specified equipment will be removed from service. NORM - (default) Removal request will be executed only if the removal will not cause interruption of service. Otherwise, the remove request will be denied. FRCD - Remove request will be executed with no regard to service interruption.incl - Confirmation field; relevant for DS1/E1 port, AMX or SMX. Enter Y to remove even if the port or any of its tributaries is part of a red-lined connection, subject to mode, or enter N (default) to remove only if neither the port nor any of its tributaries is part of a red-lined connection, subject to mode. rusure - Confirmation field; relevant for ACP and PCU types. Enter Y to remove the equipment unconditionally, or N (default) to deny the command if the request will remove an active processor.



Step Testing Hardware with Diagnostics 3 To run diagnostics, enter:

DGN-EQPT:[tid]:aid:ctag; The response reports PASS (the equipment is operational) or FAIL (the equipment must be replaced. Refer to Module Replacement Procedures).

4 To return the equipment to an in-service state, enter: RST-EQPT:[tid]:aid:ctag::[mode]; mode - the mode in which the command is implemented:

11 Compare the stored contents of the AMU and ACP with the T::DAX current software release component list, to verify successful update of the replaced unit. Verify that all items in the software release component list that reside on flash EPROMS in AMU (PCU PGM) and ACP (ACP PGM), exist and that date and version match exactly.

12 Log off T::DAX.



3.4.4. Replace the AMU Perform the following procedure to replace the AMU/TAMU/HAMU module. You will need the following items to perform the procedure:

T::DAX current software release component list.



Note: This procedure is for the replacement of the AMU as a result of a failure of the module. For a hardware or firmware retrofit or software upgrade an alternate procedure is required. The retrofit or upgrade is detailed in the Product Change Notice (PCN) issued for the specific retrofit or upgrade.

Step Replacing the AMU 1 Log onto T::DAX.

2 Verify that the current system programs reside in the DSU. If in doubt, copy them from the program backup tape to the hard disk. Insert the program tape into the TPDR and enter:

CPY-MEM::FROMMEM=AUX,TOMEM= SEC:ctag::PGM:REL=rel; rel - current release number - three digits (i.e. 7.07-B)

3 Verify that you have the current valid database on a tape. If not, copy the database from the disk to a blank tape. NOTE: It is presumed that a valid database from the last 24 hours exists on the disk (see “Recommendations”). Insert a blank tape into the TPDR and format the tape, enter: RMV-EQPT:: TPDR:ctag::FRCD; INIT-SYS::TPDR:ctag::0:RUSURE=Y; RST-EQPT:: TPDR:ctag;

4 Back up the database from the hard disk to the tape, enter: CPY-MEM::FROMMEM=SEC,TOMEM=AUX:ctag::DATA;

5 Verify that the backup was properly executed, enter: RTRV-DIR-EQPT::DSU:ctag; RTRV-DIR-EQPT::TPDR:ctag;

6 Plug out the NCU cards on the narrowband shelf. Retrieve the condition of the controllers on the shelf, enter (x = shelf number): RTRV-COND-EQPT::NCU-x-A&-B:ctag;

7 Plug out the standby NCU – Wait for the PLUGOUT message. Plug out the working NCU - Wait for the PLUGOUT message.



Step Replacing the AMU 8 To replace the faulty AMU card, first remove the card from service by entering:

RMV-EQPT::AMU:ctag::FRCD; Remove the Phillips screws securing the AMU card to the shelf, pull the extractor handles and remove the AMU card. Connect the battery jumper on the new AMU card (pins 1 and 2 shorted - see T::DAX Installation Manual), insert the card in the slot on the shelf and secure the two Phillips screws.

9 Perform the diagnostics for the new AMU card, enter: DGN-EQPT::AMU:ctag; This process may take up to two minutes. The response should be: “RESULT=PASS“

10 Restore the AMU card back to service by entering: RST-EQPT::AMU:ctag; Initialize the AMU card by entering: INIT-SYS::AMU:ctag::0:RUSURE=Y;

11 To copy the program from the hard disk back to the ACP, first start local restoration mode to prevent any disturbances to the ACP by entering. STA-LOCL-RST:::ctag; Wait for a "COMPLD" response. Then copy the programs from hard disk (SEC) to the ACP (WKG) by entering: CPY-MEM::FROMMEM=SEC,TOMEM=WKG:ctag::PGM:REL=7.1x;

Note : When the programs are copied from the hard disk to the ACP, the AMU (PRI) automatically receives the software release specified in the CPY-MEM command.

There will be two momentary flashes of the “LOAD” and “ACT” LEDs on the standby ACP. The “LOAD” LED will then turn on for a while on the standby ACP. The ACP will then initialize. During the start of initialization, the “OOS” LEDs will light on both ACPs. The “OOS” LED will then turn off on the previously active ACP and will remain lit on the standby ACP. The "ACT" LEDs on the MCUs, TCUs, SCUs and HSCUs will then turn off while the T::DAX is uploading the PCU software. As each PCU is loaded, the "ACT" LED will return.

12 Wait for the ACP end of initialization message and then exit the local restoration mode by entering: EXIT-LOCL-RST:::ctag; Wait for a "COMPLD" response.

3.5.

3.5.1. Introduction

3.5.2.

SYSTEM RECOVERY

System recovery is an initialization of processor-equipped T::DAX modules. You can perform the following types of system recovery:

Warm start. A warm start is initialization with a “valid” database. A warm start initializes individual modules, such as the ACP, AMU, CDU, DSU, control units (xCU), or TPDR. A warm start saves cross-connect and PM data. The database is valid after the following command is performed:

INIT-SYS::AMU:ctag::0;

Cold start. A cold start is an initialization with a “nonvalid” database. A cold start is performed:

− When the T::DAX is powered up

− By plugging out the AMU, disconnecting the battery jumper and plugging out the two ACPs.

Task Index Use the following index to find your task. If the task is not listed in the following index, refer to the index at the end of this manual to locate the procedure.

If Your Task Is To Initialize A: See Section:

Initialize an ACP 3.5.3

Initialize a TCU, SCU, HSCU, MCU, OCU, NCU, ECU or RCU

3.5.4

Initialize an AMU 3.5.5

Initialize an CDU 3.5.6

Initialize an DSU 3.5.7

Initialize an a Tape in the TPDR 3.5.8

Cold start T::DAX 3.5.9


Cat. No. 7979-71080-22 T::DAX Maintenance Manual Issue 3, June 2003 3.5.3. Initialize a ACP ACP initialization is a recovery task that resets the ACP/TACP/PACP/HACP to a normal software and hardware state. Use the following procedure to initialize an ACP. The active or standby ACP can be initialized.

Step Initializing an ACP

1 To initialize the ACP, enter:

INIT-SYS:[tid]:ACP-n:ctag::0:RUSURE=rusure;

n = A or B, whichever ACP is being initialized. If the active ACP is initialized it will cause a switch to standby. rusure – enter Y to initialize the processor unconditionally.

Example response (for an active ACP):

TDAX 02-01-06 17:16:16

A 001 REPT INITZN

"ACP-A:ACTIVITY=ACT,REASON=STARTOFINIT,INITMD=SOFT,DBVALID=YES"

;

<

TDAX 02-01-06 17:22:26

A 002 REPT INITZN

"ACP-B:ACTIVITY=ACT,REASON=ENDOFINIT,INITMD=SOFT,DBVALID=YES"

2 To verify that a ACP has been initialized, enter:

RTRV-COND-EQPT:[tid]:ACP-n:ctag;

n = A or B.



3.5.4. Initialize a Control Unit (xCU) Control unit processor initialization is a recovery task that resets the module processor to a normal software and hardware state. Use the following procedure to initialize a TCU, SCU, HSCU, MCU, OCU or RCU.

Step Initializing a Control Unit

1 To initialize the control unit enter:

INIT-SYS:[tid]:aid:ctag::0:RUSURE=rusure;

0 - is the degree or level of initialization (zero).

rusure – enter Y to initialize the processor unconditionally This is required to initiate the active unit. If an active unit is initialized it will become standby.

2 To verify that the processor has been initialized, enter:




3.5.5. Initialize an AMU AMU initialization is a recovery task that writes a signature sequence of bytes to the AMU/TAMU/HAMU module, allowing the system database to be restored from the AMU during future ACP initializations. Note: After an ACP initialization with no valid database on the AMU, the AMU remains in the out-of-service state and cannot be written to until this command is issued for the AMU. This is required on initial system turn up, and when the AMU is replaced. Use the following procedure to initialize an AMU.

Step Initializing an AMU

1 To initialize the AMU enter:

INIT-SYS:[tid]:AMU:ctag::0;

0 - initialization level (zero).

2 To verify that a AMU has been initialized, enter:

RTRV-COND-EQPT:[tid]:AMU:ctag;

Example response: M BRUN RTRV "AMU,EQPT:TYPEREP=IS" /*1 records retrieved*/

3 Retrieve the memory status of the AMU to verify the PCU program status on the AMU.

RTRV-MEMSTAT-EQPT::AMU:ctag;

Example response: ctag RTRV /* 0 record retrieved*/

If there are no records, as shown, the PCU programs should be downloaded from the DSU as follows:

STA-LOCL-RST::ctag; CPY-MEM::FROMMEM=SEC, TOMEM=WKG:ctag::PGM:Rel=x.xx; There will be two flashes of the "OOS" and "ACT" LEDs on the standby ACP. Then both ACP "OOS" LEDs will go on. After about 20 seconds the "OOS" LED on the ACP that is standby will go out. The active ACP "OOS" LED will stay on until the initialization is completed. After a completed initialization the "ACT" LED will turn on. This takes about 3 minutes for a basic system, 6 minutes for a double capacity system and 12 minutes for quad capacity system.



3.5.6. Initialize a CDU CDU initialization is a recovery task that initializes the timing reference algorithm that locks to the timing reference. Use the following procedure to initialize a CDU.

Step Initializing a CDU

1 To initialize the CDU enter:

INIT-SYS:[tid]:aid:ctag::1;

2 To verify that an CDU has been initialized, enter:


Example response:

M [ctag] RTRV

“CDU,EQPT:TYPEREP=IS”

3 To retrieve the CDU boot program version, enter:

RTRV-MEMSTAT-EQPT::aid:ctag;



3.5.7. Initialize a DSU DSU initialization is a recovery task that formats the disk.

Step Initializing a DSU

1 The DSU must be removed from service to initialize.

RMV-EQPT:[tid]:DSU:ctag::FRCD;

2 To initialize the DSU enter:

INIT-SYS:[tid]:DSU:ctag::0:[RUSURE=Y];

3 Restore the DSU to service.

RST-EQPT:[tid]:DSU:ctag;

4 To verify that an DSU has been initialized, enter:

RTRV-COND-EQPT:[tid]:DSU:ctag;

Example response: M BRUN RTRV

"DSU,EQPT:TYPEREP=IS"

/*1 records retrieved*/

5 Upload the system program and database to the DSU as per the procedure in section 3.4.18.



3.5.8. Initialize a Tape Tape initialization is a recovery task that erases the tape and it is necessary to remove the TPDR and the DSU by command first. Use the following procedure to initialize a tape in the TPDR.

Step Initializing a Tape in the TPDR

1 To initialize the TPDR enter:

RMV-EQPT:[tid]:TPDR:ctag::FRCD;

The DSU must also be removed to initialize the tape.

RMV-EQPT::DSU:ctag::FRCD;

2 Insert the tape to the TPDR.

To initialize the Tape enter:

INIT-SYS:[tid]:TPDR:ctag::0:[RUSURE=Y]; Restore the TPDR and DSU to service.

3 Restore service to the TPDR and the DSU. Enter:

RST-EQPT::DSU&TPDR:ctag;

4 To verify that a tape in the TPDR has been initialized, enter:

RTRV-COND-EQPT:[tid]:TPDR:ctag; The system will report that it cannot find the file if the tape has not initialized.

The tape has now been initialized and formatted. As part of a memory task the database should be loaded back onto the tape as per section 3.3.4.



3.5.9. Cold Start T::DAX If a fatal error occurs and there is no other way to correct it, perform the following procedures to cold-start T::DAX.

Step Initiating a Cold Start

1 If possible, log off T::DAX. (connect to the CIT port)
