This chapter describes system initialization procedures from either the hard disk or a floppy disk.
Power on refers to the process of supplying input power to the power subsystem.
Use the following checklist before powering on the system. Verify that all items on the list are completed before turning on the power.
1. ____ Environmental control system in equipment room is activated and set for 24-hour operation if applicable.
2. ____ System is installed and secured as required.
3. ____ System is connected to isolated ground facility.
4. ____ -48 VDC output of DC power plant to VCO/4K measures between -48V and -53V (DC models only).
5. ____ Input connections are completed to power subsystem. System main breaker/switch is OFF.
6. ____ Power subsystem is connected.
7. ____ System console is connected to Storage/Control I/O Module and powered on.
8. ____ System printer is connected to Storage/Control I/O Module and powered on.
9. ____ Remote maintenance modem is connected to Storage/Control I/O Module and -powered on.
10. ____ Data communications links between the VCO and host computer are completed.
11. ____ Host computer is powered on and initialized with communication and application -software.
Figure 3-1 shows the location of the AAC.
Before turning the power on, verify that the AAC switches are set as follows:
| AUTO | — | The AUTO setting works for both nonredundant and redundant systems as follows:
|
| A | — | Selecting A (side-A) has the same result in a redundant and a nonredundant system. Side-A is always active. |
| B | — | Selecting B (side-B) results in the following:
|
When the system is powered on, the LED for the Active system controller illuminates.
 |
Note If your VCO is equipped with Automatic Switching Units, moving the Select switch on the AAC from Side A to Side B after the system is powered on transfers control of the peripheral equipment from one Combined Controller card to the other. |
To provide power to a VCO/4K system:
The VCO's main power switch is in the rear of the VCO on the power entry module. Ensure that the power switch is down. See Figure 1-4 or Figure 1-5 to identify the main power switch.
Step 2 Connect or plug in the input power cable at the source.
Step 3 Turn the main power switch on (up position).
Step 4 Check the power LED on the power supply module. If you have a redundant system, check the power LEDs on each of the power supply modules. Refer to Figure 3-2 for the location of the power LED(s).
Ensure that the LED labeled POWER on each power supply module is illuminated green.
|
Note If any of the power LEDs fail to illuminate, or if any LED illuminates red, turn the main power switch off and on. |
The power supply LEDs are on the left side of each power supply module, which are located on the bottom front of the VCO as shown in Figure 3-2.
After the Combined Controller and the NBC3 are initialized and self-tests are completed, the active system controller always tries to initialize the system from the boot device specified by the File System Configuration utility (refer to the Cisco VCO/4K System Administrator's Guide for more information). In new systems, the hard disk drive is factory-specified as the boot device and the sequence of events automatically occurs (see the "System Initialization" section.)
If the system fails to initialize, a message on the master console requests a floppy disk in floppy drive A. For more information about booting from a floppy disk, refer to the Cisco VCO/4K System Administrator's Guide.
|
Note The system console is configured after the initial power is supplied to the VCO/4K and the checks are complete. The default console configuration is 9600 baud, 8 bits/char, 1 stop bit and no parity. These defaults should enable you to view any messages displayed on the console during the initial power-on phase of the install. |
When power is supplied to the system, the system firsts checks to determine if a floppy disk is inserted into the drive. If a disk is there, the system checks for the files necessary to boot the system from the floppy disk. If no disk is present or the boot files are not on the floppy, the system tries to read the boot files from the hard disk. If the boot files are on the hard drive, the system begins the tasks necessary for normal system operation.
|
Note The hard disk(s) is initialized and the generic software is loaded at the factory. Although initializing the hard disk should not be necessary, you can reinitialize the hard disk using the Generic Installation floppy diskettes supplied with the system (refer to the Cisco VCO/4K System Administrator's Guide for more information). |
The green hard disk drive access LED on the front of the combined controller blinks ON and OFF, indicating that files are being read.
The MAJOR alarm LED on the AAC remains illuminated during most of the initialization process. Interface and service circuit cards in the subracks illuminate all three LEDs on their front panels. As card self-tests are completed, the red and yellow (major, minor alarm) LEDs are extinguished, leaving the green LED on the AAC illuminated. The green LED on each subrack card is extinguished as each card is brought into active service.
Failure of a card self-test causes the red LED or a combination of LEDs to illuminate on its front panel, indicating a major alarm. The card does not attempt to bring itself back into active service. Refer to the Cisco VCO/4K Card Technical Descriptions for complete descriptions about LED states for each card type.
The three LEDs on NBC3 cards remain illuminated for a much longer period of time. Their All-LEDs-ON state lasts from system reset until all self-tests and program download sequences are complete. When the system is successfully booted, all the LEDs on the master NBC3 are extinguished. VCO/4K systems with redundant system control have two NBC3s and at least one DTG-2. The green LED on the Standby NBC3 and DTG-2 remain illuminated. Note that the DTG-2s are mezzanine cards attached to each respective NBC3 card.
For additional details about LED states and troubleshooting information, refer to the Cisco VCO/4K System Maintenance Manual.
The master console displays the System Login screen as the controller initialization process continues. However, full system initialization (including downloading of application software to various cards) is not complete until the following message appears on the system message line, in the lower left portion of the master console screen:
FRM001 PHASE 3 - SYSTEM INITIALIZATION COMPLETE
This information is also written to the system log files.
When all files are transferred to system memory from the hard disk, all LEDs on the port rack circuits cards are extinguished with the exception of standby (redundant) NBC3s and DTG-2s. The green LED on these cards remains illuminated to indicate the standby status.
For more information about LED patterns, refer to the Cisco VCO/4K Card Technical Descriptions.
If any of the circuit cards in the Port Subracks fail to activate during the initialization process, an error message identifying the Rack-Level-Slot address of the failed card appears in the bottom left corner of the master console display screen. You can trace card failure to a mismatch between the port subrack and the system database.
If the card fails the self-test, the red LED illuminates. If the card passed the self-test but is not brought into service by the NBC3, the green LED illuminates. The green LED remains illuminated for all cards that are set to Standby status (NBC3 and DTG-2).
Cisco VCO/4K System Messages defines other error messages that may appear. Corrective maintenance procedures appear in the Cisco VCO/4K System Maintenance Manual.
This section reviews setup parameters for the following video display terminals (VDTs) used as Master Consoles in VCO/4K systems.

For more information about the Clock/Calendar Configuration utility, refer to the Cisco VCO/4K System Administrator's Guide.
This section explains how to configure the system printer and the remote maintenance modem.
The end-of-line (EOL) terminator for the printer interface must be defined in the system database and match the printer setup configuration before using the printer. The EOL terminator is defined in the Peripheral Configuration screen.
Refer to the Cisco VCO/4K System Administrator's Guide for more information. Refer to the documentation supplied with the printer to configure the EOL terminator for the printer.
Define the modem operating parameters in the system database and match them with the modem operating parameters set in the modem. Modem operating parameters are defined in the Peripheral Configuration screen.
Refer to the Cisco VCO/4K System Administrator's Guide for more information on defining the parameters and the Peripheral Configuration screen. Refer to the documentation supplied with the printer to set the modem operating parameters.
There are three options on the Maintenance menu's Master Timing Link Selection screen for choosing the timing source.
If not using the default, internal, NBC3 timing source, use the following:
Refer to the Cisco VCO/4K System Administrator's Guide for more information.
The internal clocking source on the NBC3 is the default clocking source.
To change the clocking source from a External or Primary/Secondary source to the internal NBC3 clock, choose Internal from the Master Timing Link Selection screen.
Refer to the Cisco VCO/4K Card Technical Descriptions for more information on the NBC3 clock.
The VCO/4K systems support T1 synchronization timing source connections with the data stream on a selected port. The synchronization frequency must be 1.544 MHz, ±75 Hz. You can select one span for the primary timing link and a different span for the secondary timing link. Use only digital ports (T1 or E1).
The conversion from the PCM waveform to logic level signals and from 2.048 MHz (E1) to 1.544 MHz is done on the port card.
Select the spans from the Master Timing Link Selection screen. Refer to the Cisco VCO/4K System Administrator's Guide for more information.
The VCO/4K system supports synchronization timing source connections through a front panel jack on the Network Bus Controller 3 (NBC3) card. Connection to the external synchronization timing source must comply with the specifications in Table 3-1.
| Specifications | Value |
|---|---|
Synchronization Frequency | 64.0 kHz, ±3.0 Hz |
Signal Level | Composite clock, 60% duty cycle |
Signal Characteristics | Rise/fall — 20 ns maximum |
Mating Connector | 9-pin, D-sub |
The BITS clock connector on the faceplate of the NBC3 card is inaccessible in installations where the front door is installed on the chassis in compliance with EMI requirements. Full EMI compliance can be maintained with an available BITS Clock Cable Kit (one for each NBC3 card) that routes the BITS clock signals to a DB-9 connector on a rear faceplate.
Two external cable assemblies are required for systems equipped with redundant NBC3 cards. Cisco Systems does not provide mating cables or connectors.
|
Note If the NBC3 is the last connection in a routing of composite clock, insert the J3 jumper to provide a 130-ohm termination to the signal. |
After connecting the external timing source, choose External from the Master Timing Link Selection screen. For more information about the Master Timing Link Selection screen, refer to the Cisco VCO/4K System Administrator's Guide.
If the external timing source is lost, the system uses its internal NBC3 timing source. When the external timing source is restored, manually reset the Master Timing Link selection to External if the external timing source is to be used again.
Refer to the Cisco VCO/4K System Administrator's Guide for more information.
When the VCO/4K is initially booted from the hard disk, generic software and database tables are loaded into system memory. The generic software includes system administration menus that enable system configuration. Some of the hardware configuration information is preloaded at the factory.
Using the system database, the system administrator defines the connection between system components and the telecommunication environment in which the VCO/4K operates.
 |
Caution In a redundant configuration, both system controllers must be booted from the hard disk before configuring the system. |
During system initialization, configuration data is loaded from the hard disk into RAM. The system controller refers to the database tables as it processes calls and monitors system performance.
When the system is booted from hard disk, any changes made to the database are simultaneously written to RAM and the hard disk and are immediately used to process calls.
Each system is shipped with software that includes generic operating and application software. Installation utilities format the hard disk and create blank lookup tables. The VCO/4K database contains two NBC3 cards and one DTG-2 card in its card table.
In redundant system configurations, both controllers must be initialized from the hard disk before you enter configuration information into the system. To initialize redundant system controllers, follow these steps:
Step 2 Simultaneously press Reset A and Reset B on the AAC to boot both controllers from the hard disk. The VCO/4K automatically initiates file synchronization. Depending on the size of the database, this process can take up to 10 minutes. When the process is complete, the following messages are written to the log file. They also appear on the console.
ACT File Sync Complete
STBY File Sync Complete
Step 3 You can now enter configuration information into the system database. Ensure that any changes you make are on the active system controller. For information about entering configuration information into the system database, refer to the Cisco VCO/4K System Administrator's Guide.
|
Note Portions of the VCO/4K system database are not redundant (automatically updated on the standby controller). Before operating the VCO/4K with the updated configuration, enter the configuration information on the standby controller for the following screens: Host Configuration Peripheral Configuration File System Configuration System Trace Configuration |
Step 4 When all the configuration information is entered into the system database, back up the hard disk from the Disk Utilities menu. For more information about backing up the hard disk from the Disk Utilities menu, refer to the Cisco VCO/4K System Administrator's Guide.
|
Note If either controller fails to boot from the hard disk, press the Reset button on the AAC for the failed controller. If the controller still fails to boot after file synchronization completes, boot the failed controller from floppy disk. For more information about booting a controller from floppy disk, refer to the Cisco VCO/4K System Administrator's Guide. |
When you power on the VCO, configure and send test messages from the host computer through the communication links between the VCO and the host computer to verify the link is up and running. To configure these messages, define data communication operating parameters from the Host Configuration screen.
For information about defining data communication operating parameters from the Host Configuration screen, refer to the Cisco VCO/4K System Administrator's Guide.
Testing these messages requires that the host computer is operating with communication software and enabled I/O ports.
|
Note The host communication ports must match the interface requirements of the host computer and all configuration data must be entered before testing the host communication links. |
Test host communication links by enabling the VCO/4K System Trace Configuration utility and echoing host messages back to the host terminal. This type of testing requires that the application and communications software be running on the host computer.
For information about enabling trace and message return facilities, refer to the Cisco VCO/4K System Administrator's Guide, Cisco VCO/4K Standard Programming Reference, and Cisco VCO/4K Extended Programming Reference. Enabling the trace facility causes host messages to be printed on the VCO/4K printer and/or trace files to be printed on the system hard disk. The message return facility loops any host messages back to the host computer.
If the trace and message return facilities fail to communicate with the VCO/4K, a protocol analyzer or other such device may need to be inserted in the communication link(s) to determine where the fault is occurring.
Typical communication link problems during system startup include:
To verify cabling and configuration settings, refer to the Cisco VCO/4K Site Preparation Guide and the Cisco VCO/4K Ethernet Guide.
