DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 Management Terminal Page 3-27 Logging On 3 For security reasons, the password is not displayed as you type it. The system verifies that a valid login and password name were entered. If an invalid login or password name was entered, the screen displays login incorrect: In this case you must repeat the procedure. If your password has expired or is within 7 days of the expiration day, you see a error message: Your Password has expired; enter a new one Old Password: New Password: WARNING: your password will expire in xx days If the system recognizes the login and password name, the screen displays the software version number followed by the prompt: Terminal Type (Enter 513, 4410, 4425, or VT220): [513] 4. Depending on your terminal type, enter one of the following: 5. You can deactivate INADS alarm origination whenever you log in as craft. After you supply the terminal type information requested, the system will display the following if alarm origination is activated on the Maintenance System-Parameters screen: Suppress Alarm Origination: [y] The default answer is yes. If you do NOT wish to suppress alarm origination, enter no. Any other entry will default to yes. The test inads-link command will work regardless of whether you have overridden INADS alarm origination. 6. The screen will display: enter command: The system is now ready to execute maintenance commands. Press the HELP key to display a list of all valid entries. If you have a High-Priority Bulletin Board Message, the command line prompt will include the following notification to all users who are logged in: -High-Priority Bulletin Board Messages Entered:Terminal Type Entry 513 BCT 513 (default) 715 BCS 513 (default) 4410 Data Terminal 4410 4425 Data Terminal 4425 DEC VT220 VT220
DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 Management Terminal Page 3-28 Logging Off 3 Logging Off The terminal should be logged off whenever it is not in use to avoid accidental or malicious entries that could corrupt translations or disrupt operations. This also re-enables INADS alarm origination so that alarms will not go unreported. To log off, simply enter logoff at the command prompt. The screen should then display: login: If no entry is made for 30 minutes during a craft login, the system automatically times out and terminates the login. At that time, any unresolved alarms that have not been reported to INADS will be reported. If you are logged in at more than one G3-MT terminal, the system waits until the last terminal times out or logs off before reporting such alarms to INADS. Logoff Notification alerts system administrators of enabled features that present a significant security risk. The user may be required to acknowledge the notification before the logoff is completed
Initialization and Recovery Page 4-1 4 DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 4 4Initialization and Recovery When the system is powered up, or when it experiences a catastrophic fault that interrupts its basic functions, it undergoes a reboot. In addition to reboot, there are several less severe resets available for the system to recover from less disrupting errors. The technician can also initiate these resets with a command. !CAUTION: System resets can have wide-ranging disruptive effects. Unless you are familiar with resetting the system, follow normal escalation procedures before attempting a demand reset. If a reset fails to recover normal system operation, the firmware that controls reset will escalate to the next higher level, up to reboot if necessary. A failure to reboot results in SPE-down mode, which is described in later in this chapter. This chapter describes the causes, effects, and duration of each reset level. In a system with duplicated SPE, the standby SPE can undergo a reset without disrupting service since the active SPE remains in control. These resets can also be requested with the corresponding reset standby-spe level commands. All standby resets turn off memory shadowing, leaving the standby SPE temporarily unavailable for service. Refresh of the standby typically takes several minutes. When resets occur, including interchanges, an error is logged against the maintenance object “SYSTEM.” The error code gives information about the cause of the reset. Information about the reset is also logged in the initcauses log. See display initcauses in Chapter 8, ‘‘ Maintenance Commands’’. The EPNs can also undergo individual resets. These are described in ‘‘ EXP-INTF (Expansion Interface Circuit Pack)’’ and ‘‘EXP-PN (Expansion Port Network)’’ in Chapter 9, ‘‘ Maintenance Object Repair Procedures’’. PNC interchanges are

Hot Restart This reset occurs only on a duplicated SPE during a planned SPE interchange. Reset Level 1 (Warm Restart) Duration Up to 1.5 minutes Causesreset system interchange command (use of the contention-override or health-override options causes a reset level 1 or higher) SPE interchange requested by scheduled maintenance Effects Call service is unaffected. Yellow LEDs light on new active SPE and go out on the new standby. Memory shadowing is turned off. Remote access port (SYSAM-RMT) login is dropped. Duration Up to 10 seconds, typically 2 seconds Causesreset system 1 command Spontaneous SPE interchange (those caused by hardware faults) Software faults that are non-service affecting Abort of planned SPE interchange Hardware bus errors TN1655 Packet Interface faults
DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 Initialization and Recovery Page 4-4 Reset Level 1 (Warm Restart) 4 Effects Stable calls are preserved. System links, and stable feature and service state data are preserved. Error and alarm logs are preserved, but all alarms are resolved except for STBY-SPE and busyouts. Transient calls (not yet connected), and some user stimuli, are dropped. New calls are not processed during the reset. G3-MT logins, including remote access and system port logins, are dropped. If the reset resulted from a spontaneous SPE interchange, memory shadowing is turned off, and the standby SPE will not be available for service until memory is refreshed (several minutes). Application links such as those to AUDIX and CDR are dropped and reestablished in under 2 1/2 minutes. (BX.25 links are not dropped, and CDR data is buffered during the outage.) MSS activity is aborted. Translation data is preserved, but if translation changes were in progress, the reset is escalated to Reset Level 3 (Cold-1). If core dump is enabled for this reset level, reset is delayed until the core dump is complete.

All calls are dropped. Non-translation feature data, such as Automatic Wakeup calls, are lost and must be reentered. All G3-MT logins, including remote access and system port logins, are dropped. Initialization firmware runs diagnostics and displays results on the G3-MT screen. SPE memory shadowing is turned off, leaving the standby SPE unavailable for service for several minutes. All hardware components, except PNC components, are reset, including the EPNs. All standby Expansion Interfaces, and the active EI in the PPN are reset. SNIs, SNCs, DS1Cs and active EIs in the EPNs are not reset. If the PNC is duplicated, a global refresh of the standby PNC is performed after the reset. All busied out maintenance objects are released and must be rebusied, if so desired. Circuit packs are reinitialized, (translations are verified by comparison to physical board locations). If core dump is enabled for this reset level, reset is delayed until the core dump is complete. Error and alarm logs are preserved, but all alarms are resolved except for STBY-SPE and busyouts.

Translations are reloaded from disk or tape. If core dump is enabled for this reset level, reset is delayed until the core dump is complete. Translations entered by users since the last save translation was executed by command or by scheduled maintenance are lost. Duration Typically 8 to 11 minutes Causesreset system 4 command Escalation from reset level 3 Power up Recovery attempt from SPE-down mode (requested by reboot command, or automatically every 20 minutes) Spontaneous interchange into an unrefreshed standby SPE Effects System software (boot image) is reloaded, and all processes are reinitialized The disk, if present and healthy, is the default device from which the software is loaded. Otherwise, the reload is taken from tape Before reboot, the system attempts to save the alarm and error logs to the disk on the active SPE After reboot, error and alarm logs are restored from the SPE that is active coming out of the reboot. (Note that this means that some error and alarm information may be lost if the last save before the reboot save does not succeed or if an SPE interchange takes place)
DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 Initialization and Recovery Page 4-7 Reset Level 5 (Extended Reboot) 4 Reset Level 5 (Extended Reboot) Initialization Diagnostics For each reset level, the system performs a series of diagnostic tests on components of the SPE to confirm that the system can be brought into service. The management terminal displays the result of each test as it occurs. If a reboot fails, and the system cannot bring itself up, SPE-down mode is invoked. A description of this mode, with troubleshooting procedures available to it, appears in the following section. Table 4-1 shows the diagnostic tests run during initializations. Level 1, 2 and 3 resets 4 perform the first 11 tests (through the Timer Test). Reboots complete all tests in the table except the last one. Only extended reboots execute the Memory Board Couple Test. If a test fails, make the indicated repair. If more than one repair is indicated, perform them in the order shown until the problem is resolved. Follow procedures described in ‘‘ Replacing SPE Circuit Packs’’ in Chapter 5, ‘‘Responding to Alarms and Errors’’. Other effects are the same as those in reset level 3, except that more extensive diagnostics are performed. If reboot fails, SPE-down mode is invoked. If a core dump is enabled for this reset level via the set vector command, the reboot is delayed until the core dump has completed. Duration Up to 25 minutes Causesreset system 5 command This reset is invoked only by command Effects Effects are the same as for a level 4 reboot except that more extensive diagnostics are performed. This reset is used to diagnose SPE component failures not detected by level 4 reboot tests.
