Card Installation

This chapter describes how to install circuit cards and baffles in the ASR 5500 chassis.

It includes the following sections:

Card Slot Assignments

The tables below show recommended card slot assignments for typical installation scenarios. The recommended card assignments are based on the multiple power planes sourcing power to the card slots. Refer to the Power Planes section of the Power Cabling chapter for additional information.

Following the recommendations preserves redundant operation if input power is lost to one or more of the power circuits on the PFUs.

General Installation Sequence

Circuit cards and baffles are installed in the ASR 5500 chassis as follows:
  • Front circuit cards and baffles are installed from Right to Left. Start at slot 20 and continue to slot 11. Slots 19 and 20 always require baffles.
  • Rear circuit cards and baffles are installed from Left to Right. Start at slot 1 and continue to slot 10.

Complete the installation of each card (includes securing the card in the chassis using a Phillips #2 screwdriver before proceeding to the next card.

You can install all circuit cards and then install baffles to cover empty chassis slots. It does not matter whether you install all front cards or all rear cards first.

See the diagram below.

Figure 1. Installing Circuit Cards and Baffles

Card Interlock Switch

Except for rear baffles, ASR 5500 cards include top and bottom ejector handles that incorporate hooks that fit behind the upper and lower rails of the card cage. Lifting the ejector handles outwards ejects the card from the midplane. Pushing the ejector handles inwards seats the card into the midplane.

The top ejector handle incorporates an interlock switch that signals the system that a card is seated in the slot. The blue subhandle must be pushed fully upward to engage the interlock switch. The subhandle also locks the top ejector handle against the front of the card. Tightening the captive Phillips #2 screw within the top ejector handle secures the subhandle and circuit card to the card cage.

Circuit Cards

The installation procedure described below is identical for all circuit cards in the chassis. Circuit cards include: SSC, FSC, DPC/UDPC, DPC2/UDP2, MIO/UMIO.

Prerequisites


Caution

During installation, maintenance, and/or removal, wear a grounding wrist strap connected to the ASR 5500 chassis to avoid ESD damage to the components. Failure to do so could result in damage to sensitive electronic components and potentially void your warranty.

Important:

Save several of the shipping cartons and ESD protective bags for use if a card must be returned to Cisco for fault analysis.

Important:

On a chassis equipped with the cable management tray, you must lower the tray to insert rear circuit cards. Refer to the Lowering the Cable Management Tray section in the Cable Management System Installation appendix. The cable management tray can be installed after all rear cards have been installed.

Important:

Install cable management brackets on MIO cards before inserting the card into the chassis. Refer to the Installing Cable Management Brackets section in the Cable Management System Installation appendix.

Installing Circuit Cards

    Step 1   Determine the type of card you are installing. The card type is identified by the label within the bottom ejector handle of the card.
    Step 2   Determine in which chassis slot to install the card based on the information in the tables at the beginning of this chapter.
    Step 3   Install front cards from Right to Left. Complete the installation sequence described in Steps 5 through 9 for each card before proceeding to the next card. This includes tightening the captive screws in the ejector handles using a Phillips #2 screwdriver.
    Step 4   Install rear cards from Left to Right. Complete the installation sequence described in Steps 5 through 9 for each card before proceeding to the next card. This includes tightening the captive screws in the ejector handles using a Phillips #2 screwdriver.
    Step 5   Position both ejector handles on the circuit card to be up and away (outwards) from the front panel of the card.
    Step 6   Properly support the weight of the card and align it with the upper and lower card guides of the chassis slot. Gently slide the card into the slot until the levers touch the chassis frame.
    Important:

    When installing cards that contain heat sinks, avoid any contact with an adjacent card. Such contact may loosen a heat sink as the card is being slid into the chassis slot.

    Caution   

    Never use a cable management bracket on an MIO /UMIO card to lift or insert the card into the chassis. The bracket is not designed to support the weight of the card.

    Step 7   Push both ejector handles inward firmly until the card is seated in the chassis midplane and you cannot push the ejector handles in any further. Press firmly on the card's faceplate to ensure that it is fully seated. The card's front panel should be flush against the chassis' upper and lower card mounts for the slot.
    Step 8   Raise the blue subhandle under the top ejector handle to engage the interlock switch. The subhandle also locks the top ejector handle to the front panel.
    Step 9   To secure the card to the chassis, use a Phillips #2 screwdriver to tighten the captive screws within the top and bottom ejector handles.
    Step 10   Repeat step 1 through step 7 for every card you are installing at the rear and front of the chassis.

    Baffles


    Caution

    To ensure proper ventilation, baffles must be used in any chassis slot that is not occupied by a circuit card.

    Baffles consist of a blank front panel mounted to a formed metal baffle. The baffle slides into the card slots and provides a directed path for air flow. There are two types of baffles – front and rear.

    Figure 3. Front and Rear Baffles

    Installing a Front Baffle

      Step 1   Flip both ejector handles outward from the front of the card.
      Step 2   Install front baffles from Right to Left. Complete the installation sequence described in Steps 3 through 6 for each card before proceeding to the next card. This includes tightening the captive screws in the ejector handles using a Phillips #2 screwdriver.
      Step 3   Align the baffle within an unused chassis slot.
      Step 4   Slide the card into the slot until its front panel is flush with the upper and lower card rails.
      Step 5   Push the ejector handles inward until they are flush with the front of the card.
      Step 6   To secure the card to the chassis, use a Phillips #2 screwdriver to tighten the captive screws within the top and bottom ejector handles.
      Step 7   Repeat step 1 through step 5 for any additional unused chassis slots.

      Installing a Rear Baffle

        Step 1   Install rear baffles from Left to Right. Complete the installation sequence described in Steps 2 through 4 for each card before proceeding to the next card. This includes tightening the screws at the top and bottom of the baffle using a Phillips #2 screwdriver.
        Step 2   Align the baffle within an unused chassis slot.
        Step 3   Slide the card into the slot until its front panel is flush with the upper and lower card rails.
        Step 4   To secure the card to the chassis, use a Phillips #2 screwdriver to tighten the captive screws at the top and bottom of the baffle.
        Step 5   Repeat step 1 through step 3 for any additional unused chassis slots.

        Save Shipping Cartons

        Save several of the shipping cartons and protective ESD bags in which the circuit cards were packaged. Use the cartons to package a circuit card for shipment back to Cisco for failure analysis and replacement. For additional information, refer to the Returning Failed Components in the Replacing Components chapter, and the RMA Shipping Procedures appendix.
