In this section:
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 sufficient screen captures are provided to guide you through the procedures.
It is recommended that before extracting a system card, you attach a grounding strap to your wrist or ankle and the ESD ground jack located on the front or rear panels of the chassis. Refer to DSC 8000 ESD Requirements for the locations of the ground jacks on the DSC Platform chassis.
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.
A #2 Phillips-head screwdriver is required to loosen the faceplate retention screws on all cards installed in the DSC 8000 chassis.
An extraction tool such as the AMC Xtractor that is manufactured by Xtech, is required for card removal. The following illustration shows this extractor tool. Two extraction tools are provided with the DSC 8000 chassis in the shipping container accessory box at the time of deployment. Additional extraction tools can be obtained from Ribbon (Ribbon PT-Q0AMCEX-31004). Contact Sales for more information.
Xtractor tool needed for AMC and MCH card removal
Extracting a card compromises the airflow to cards remaining in the system. Make sure that a replacement card or the appropriate Air Management Blade is readily available to fill the vacated slot. Refer to Supported Air Management Blades (AMBs).
When following the insertion and extraction procedures, the proper card removal and insertion sequence must be followed to avoid damage to the hardware. The system cards must be removed in the following order:
- Pull ejector on FRONT card (AMC671 MCH, AMC124 CPU, or AMC348 I/O) - wait for Blue LED to be solid
- Pull ejector on REAR card (RMC670 µRTM, RMC110 µRTM, or RMC348 uRTM) - wait for Blue LED to be solid
- Unscrew and remove REAR card
- Unscrew and remove FRONT card
Following these instructions avoid excessive force applied to the front card during extraction and ensures the connectors are properly seated in their slots (refer to Seating AMCs, MCHs, and µRTMs) during card insertion.
You can extract DSC Platform cards on a live system. The faceplate ejection handle, when pulled, activates a switch that starts the card's internal shutdown process. A card that has completed the shutdown process and is subsequently removed from a slot, does not affect other cards installed and running in the chassis.
Extracting a System Card
Before extracting a system card from the DSC 8000 chassis, it is recommended that you verify the status of the given card using the Slot Monitor.
Before extracting a system card, the Slot Monitor should show the following for the card's status:
- Slot Type: <card type>
- Slot Status: AVAILABLE
After extracting a system card, the Slot Monitor should show the following for the slot's status (after about one minute) from which you extracted this card.
- Slot Type: vacant
- Slot Status: EXTRACTED
If the Slot Monitor does not display the slot status after a system card is extracted as shown in the preceding bulleted list, the extraction was unsuccessful, and, therefore, the system card is still in the slot or the connection to the system card is lost.
To verify a system card status before extracting this card
- From the Main Menu, click Slot Monitor.
- For detailed information about the system card that you have extracted, click the required slot number.
The following screen capture shows the details for a successfully extracted system card.

Optionally Decommissioning an RMC110 µRTM and an AMC124 Routing CPU
If an optional Routing CPU is being removed permanently or is being moved to another slot, prior to extracting this card, the given card must be decommissioned.
The two mandatory Routing CPUs in slots 3 and 12 cannot be decommissioned.
If an optional Routing CPU is being removed in order to replace it with another card of the same type (for example to replace a broken card), then do not decommission this card before you extract the given card.
This section provides you with instructions for decommissioning a Routing CPU. Decommissioning a Routing CPU comprises the following steps:
- obtain a complete backup [(recommended) (see To execute a complete configuration backup for the DSC 8000 using a USB key)]
- decommission the Routing CPU (see To decommission a Routing CPU)
- extract the CPU from its slot (see To extract an RMC110 µRTM (rear card) and an AMC124 (front card)
- cover an empty slot with an AMB [(if required) (see To cover an unpopulated slot with an AMB)]
To decommission a Routing CPU

To cover an unpopulated slot with an AMB
Extracting a card compromises the airflow to cards remaining in the system. Make sure that a replacement card or the appropriate Air Management Blade is readily available to fill the vacated slot. Refer to Supported Air Management Blades (AMBs).
The procedure for extracting Air Management Blades is identical to the procedure for extracting the AMC348. The only difference being is that the AMBs are not equipped with ejection handles; therefore, follow the instructions for extracting AMC348, but skip the steps for using the ejection handles.
