Installing and Removing a SPA Interface Processor

Online Insertion and Removal

The Cisco uBR10012 router supports online insertion and removal (OIR) of the SPA interface processor (SIP) and of the shared port adapters (SPAs). Therefore, you can remove a SIP with its SPAs still intact, or you can remove a SPA independently from the SIP, leaving the SIP installed in the router.

Important:

If you are replacing the SPA after a duration of three months, perform a field upgrade of the SPA. Do not perform an OIR. For more information on field upgrade, see Field Upgrade of the SPA.


Note

If the SIP is running normally in chassis, SPA cards can be installed and removed directly from SIP without installing SIP.

Preparing for Online Removal of a SIP

See “Preparing for Online Removal of a SIP” section in the Cisco uBR10012 Universal Broadband Router SIP and SPA Software Configuration Guide.

For more information about the recommended procedures for physical removal of the SIP, see SIP Installation and Removal chapter.

Handling SIPs

Each SIP circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage. Before you begin installation, see Required Tools and Equipments section for a list of parts and tools required for installation.


Caution

Always handle the SIP by the carrier edges; never touch the SIP components or connector pins.

Figure 1. Handling a SIP



When a slot is not in use, a blank filler plate must be installed in the empty slot to allow the router or switch to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the installed modules. If you plan to install a SIP in a slot that is not in use, you must first remove the two blank filler plates.


Caution

The Cisco Wideband SIP and Cisco SIP-600 each weigh 10 lb. Use both hands while handling the SIPs.

SIP Installation and Removal

Installing SIP


Warning

When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the SIP. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the midplane or backplane with your hand or any metal tool, or you could receive an electrical shock.

Before You Begin

Ensure that you remove any existing line card configuration from the SIP slots.

Procedure
    Step 1  

    Attach a grounding wrist strap to your wrist and to a bare metal surface on the chassis or frame.

    Caution   

    A SIP weighs 10 lb (4.54 kg). Use two hands when handling the SIP.

    Step 2  

    Grasp the faceplate of the SIP with one hand and place your other hand under the SIP (to support the weight of the SIP) and position the SIP in front of the appropriate card cage slot.

    Note   

    The SIP ejector levers must be positioned in the open position before the SIP makes contact with the backplane.

    Step 3  

    Carefully align the upper and lower guides on the SIP with the upper and lower guides in the chassis and slide the SIP into the module slot until you can feel it begin to seat in the backplane connectors.

    Step 4  

    Simultaneously pivot both SIP ejector levers toward each other (until they are parallel to the faceplate) to firmly seat the SIP in the router backplane.

    Figure 2. Closing the Ejector Levers



    Note   

    When the router chassis is fully populated, seating a SIP can be difficult. To properly seat the SIP and avoid physical damage, loosen the captive screws on the neighboring SIPs or line cards.

    Caution   

    Use of excessive force can damage the router or SIP.

    Step 5  

    Tighten the top and bottom captive screws on the SIP to secure it in the chassis.

    Step 6  

    If needed, install the SPAs. See Installing a SPA in a SIP section.

    Step 7  

    Install the interface cables. We recommend that you clean the fiber-optic connections before attaching the cables. See the Inspection and Cleaning Procedures for Fiber-Optic Connections document.

    Removing SIP


    Tip

    To prevent alarms from activating, you can administratively shut down a SIP before hot-swapping it. Otherwise, inform the network administrator that this portion of the network will be temporarily interrupted.


    Warning

    When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the SIP. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the midplane or backplane with your hand or any metal tool, or you could shock yourself.

    Procedure
      Step 1  

      Attach a grounding wrist strap to your wrist and to a bare metal surface on the chassis or frame.

      Step 2  

      Face the back of the Cisco uBR10012 chassis. Clear aside enough interface cables and power cables to allow sufficient space to work.

      Step 3  

      Identify the SIP to be removed and unplug the interface cables connected to the SIP. Be sure to note the current connections of the cables to the ports on the SPAs installed in the SIP.

      Step 4  

      Unscrew the top and bottom captive screws on the SIP.

      Captive screws
      Step 5  

      Simultaneously pivot both SIP ejector levers away from each other to disengage the SIP from the backplane.

      Figure 4. Opening the Ejector Levers



      Note   

      A SIP weighs 10 lb (4.54 kg). Use both hands to handle the SIP.

      Step 6  

      Touching only the metal card carrier, slide the SIP out of the slot. Place the SIP on an antistatic surface, or in an antistatic bag.

      Figure 5. Removing the SIP



      Step 7  

      If you are not installing a new or replacement SIP, install blank filler plates to cover the slots and tighten the captive screws on the blank filler plates.

      Warning   

      Blank faceplates (filler panels) serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards and faceplates are in place. Statement 1029
