Failure to follow proper Electrostatic Discharge (ESD) guidelines when handling sensitive hardware can damage the equipment. Refer to the Ribbon ESD procedure Connecting Electrostatic Discharge Wrist Strap for information on protecting yourself and the equipment.
The screws on the card are for retention of the card in the chassis only. They are not intended to be used to seat the card. Screws should only be finger tightened to initial contact with the extended flanges. Do NOT over tighten screws past initial contact with the extended flanges. Over tightening the screws can result in damage to the card and chassis.
When tightening screws, use only finger pressure on the driver. It is best to grip the handle of the driver with only finger tips to ensure excessive force is not applied to the screws.
The retention screws are spring loaded to prevent them from inhibiting the faceplate from making full contact with the chassis.
In order to avoid cross threading the screws when tightening, gently push on the screw with the driver until nut bar contact is made. Gently turn the driver anti-clockwise until you feel the threads of the fastener settle into the threads of the receiving hole. This will make a slight clicking noise and will be felt through the driver. Once the threads have aligned, turn the driver clockwise to secure the screw. The screw should go in smoothly. If resistance is felt, turn the driver anti-clockwise again to re-align the threads before proceeding.
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.
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:
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 tasks in the same order as they are presented to avoid damaging the system.
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. For more information, refer to Seating AMCs, MCHs, and µRTMs for additional details.
Check the firmware version of the replacement cards and update them as required (for information about updating the DSC 8000 firmware, refer to Appendix A: Updating Firmware on the DSC 8000).
Start
If an RMC670 µRTM is installed in the rear card slot of the chassis, remove this µRTM before inserting the AMC671 MCH in the front card slot to avoid damage to the hardware. The proper card insertion sequence must be followed or the connection can be damaged.
Open the AMC671 MCH faceplate Ejection Handle switch by gently pulling it toward you. Two audible clicks can be heard during this action. Pull the card until you can hear the second click.
Remove the protective insulating tape on the battery pack of an AMC671 MCH card.
Line up the top and bottom AMC671 edges with the required slot guides located in front of the mid-plane connector of the chassis.
Carefully slide the AMC671 MCH card back toward the mid-plane of the chassis until the card edge connector is seated in the mid-plane connector and the faceplate is flush with the chassis.When the card edge connector is seated and makes proper contact with the mid-plane connector, the blue hot-swap LED turns ON.
Applying excessive force to seat a double wide card in the chassis may damage the hardware. Finger tighten the faceplate retention screws until they contact the extended flanges to secure the faceplate in the chassis.
Using a #2 Phillips-head screwdriver, turn the retention screws clockwise until they are in contact with the extended flanges. Do NOT over tighten the screws.
Double-wide cards require the faceplate to be fully seated and flush with other cards before securing with screws. Once fully seated, tighten the screws until they contact the extended flanges. Do NOT over tighten the screws.
When the ejection handle switch is closed (pushed in), the hardware connection process begins. The card is operational when the blue hot-swap LED turns OFF.
Do not activate an AMC671 MCH before the RMC670 µRTM is installed and activated to avoid damage to the hardware.
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 tasks in the same order as they are presented to avoid damaging the card.
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. For more information, refer to Seating AMCs, MCHs, and µRTMs for additional details.
Check the firmware version of the replacement cards and update them as required (for information about updating the DSC 8000 firmware, refer to Appendix A: Updating Firmware on the DSC 8000).
The following table provides an overview of the AMC124 CPUs supported on the DSC 8000.
AMC124 CPU | Control Shelf | Slot Number | Expansion Shelf 1 | Expansion Shelf 2 | Expansion Shelf 3 |
---|---|---|---|---|---|
Management | Required | Slot 2 and 13 | N/A | N/A | N/A |
Routing | Required | Slot 3 and 12 | N/A | N/A | N/A |
Routing or Application | Optional | Slots 4 to 11 | Slots 16 to 27 | Slots 30 to 41 | Slots 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, SCCP routing, Global Title Translation (GTT), Gateway Screening (GWS), Integrated Monitoring Feed (IMF), and Diameter and SIGTRAN protocols. 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.
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 Controller (DSC DB) and SS7 Database Application (SDA) applications.
The procedures for installing Management and Routing CPUs are provided in this page. For assistance installing an Application CPU, contact Customer Support.
Start
When replacing a µRTM (rear card), do not allow the card to boot up. The boot sequence MUST be interrupted before the slot boots. Refer to Boot up the BIOS for directions on how to interrupt the boot sequence.
