Note

The screen captures in the procedures on this page are examples only and may show other releases than the ones applicable to the current release. However, the procedures are accurate and are applicable to this release.

For simplicity, not all steps are presented with screen captures, but there are sufficient screen captures to guide you through the procedure.

Required Equipment

A #2 Phillips-head screwdriver is required to tighten the faceplate retention screws.

Before Installation

Before installing an AMC671 MCH card in the chassis, remove the protective insulating tape from the battery. Refer to the following figure for the location of the tape on the card.

Figure : Protective battery tape installed on MCH card at the factory

Installing a System Card

Before installing a system card in the DSC 8000 chassis, it is recommended that you verify the status of the slot (using the Slot Monitor) into which you are planning to insert the given card.

Before installing a system card, the Slot Monitor should show the following for the slot's status:  

  • Slot Type: vacant
     
  • Slot Status: EXTRACTED

After installing a system card, the Slot Monitor should show the following for the card's status (after about one minute):

  • Slot Type: <card type>
     
  • Slot Status: AVAILABLE

To verify a system card status after installing this card

  1. From the Main Menu, click Slot Monitor.



  2. For detailed information about the system card that you have installed, click the required slot number.

    The following screen capture shows the details for a successfully installed system card.

Installing an AMC671 MCH and an RMC670 µRTM

Follow the instructions in this section to install an AMC671 MCH and an RMC670 µRTM in a DSC 8000 chassis. It is highly recommended that you execute the task in the same order as they are presented to avoid damaging the system.

Caution


When following the insertion and extraction procedures, the proper card insertion and removal sequence must be followed to avoid damage to the hardware. The AMC671 MCH must be installed first before the RMC670 µRTM is installed in the chassis to avoid damage to the hardware. Following this order avoids excessive force applied to these cards during insertion, and ensures that the connectors are properly seated in their slots. See Seating AMCs, MCHs, and µRTMs for additional details.

Caution

 Check the firmware version of the replacement cards and update them as required (for more information about firmware, refer to Appendix A: Updating Firmware on the DSC 8000).

Installing an AMC124 CPU and an RMC110 µRTM

This section provides you with information for installing an AMC124 CPU (front card) and its RMC110 µRTM (rear card). It is highly recommended that you execute the task in the same order as they are presented to avoid damaging the card.

Caution


When following the insertion and extraction procedures, the proper card insertion and removal sequence must be followed to avoid damage to the hardware. The AMC124 CPU must be installed first before the RMC110 µRTM is installed in the chassis to avoid damage to the hardware. Following this order avoids excessive force applied to these cards during insertion, and ensures that the connectors are properly seated in their slots. See Seating AMCs, MCHs, and µRTMs for additional details.

Caution

 Check the firmware version of the replacement cards and update them as required (for more information about firmware, refer to Appendix A: Updating Firmware on the DSC 8000).

Overview of the Supported AMC124 CPUs on the DSC 8000

The following table provides an overview of the AMC124 CPUs supported on the DSC 8000.

AMC124 CPUControl ShelfSlot NumberExpansion Shelf 1Expansion Shelf 2Expansion Shelf 3
ManagementRequiredSlot 2 and 13N/AN/AN/A
RoutingRequiredSlot 3 and 12N/AN/AN/A
Routing, Application, or CustomOptionalSlots 4 to 11Slots 16 to 27Slots 30 to 41Slots 44 to 55

The Management CPUs are used for system administration functions and are equipped with hard drives for long term storage. These CPUs have been designed with a redundant online/standby Operation, Administration and Maintenance (OA&M) architecture.

The Routing CPUs provide the processing functions for MTP3 routing, Global Title Translation (GTT), Gateway Screening (GWS), and SIGTRAN. These processes operate in a load-sharing mode providing automatic failover capability in the event of errors and at the same time ensuring the system is equipped to handle peak traffic loads.

Note

On the DSC 8000, the DSC and SIGTRAN traffic are supported on the same Routing CPU; however, the traffic must be provisioned and transmitted on different subnets. 

The Application CPUs are dedicated to the Diameter Signaling Controler (DSC DB) or SS7 Database Application (SDA) applications.

The Custom CPUs are used for third-party software applications.

Custom CPUs have been developed for future use; therefore, no instructions are provided for installing and configuring these CPUs. For more information about the Custom CPUs, contact Sonus Sales.

The procedures for installing Management and Routing CPUs are provided in this page. For assistance to install an Application CPU, contact Customer Support.

If you are replacing the RMC110 µRTM or adding a new AMC124 CPU and an RMC110 µRTM, then follow the procedure in this section. 

If you are replacing the AMC124 CPU (front card), there is no need to reinstall the O/S. In this case, follow the procedure described in the To add a new license on the DSC Platform in the Platfrom manager User Guide. When the new license has been installed, it is recommended that you create a backup as descibed in the Complete System Backup (using a USB key).

 

 

If you are only replacing the AMC124 CPU Front Card, then there is no need to re-install the O/S. In this case, follow the procedure described in To add a new license on the DSC Platform in the Platform Manager User Guide. Once the new license has been installed, it is recommended to create a backup as described in Complete System Backup (using a USB key)

Commissioning an AMC124 Application CPU

This section provides you with instructions for commissioning a DSC DB Application CPU. Commissioning a DSC DB Application CPU comprises the following two steps:

Caution

The DSC DB CPU must be commissioned and configured in a pair for redundancy purposes.

Note

Commission the DSC DB Application CPU by following the steps in the procedure in the order presented.

The screen outputs in this page are examples only and may show software versions other than the ones that are supported for this release; however, the procedure for commissioning a DSC DB Application CPU is the same.

Complete System Backup (using a USB key)

It is recommended that you use a 16GB USB key for a complete system backup. To perform this backup, you have to insert this USB key into the the USB port on either the AMC124 Management CPU or its respective RTM (slot 2 or slot 13). The location of these USB ports are shown in the following two illustrations.

   

  • The term configuration data in this document refers to the system and application configuration data.
       
  • Log files, with the exception of the upgrade log associated with the application load, are not included in a complete system backup and restore.
       
  • License files are not compatible across cards, systems, and software versions; therefore, these files are also excluded from a complete system backup and restore.
