Preparing a Full-Height Line Card Slot

This appendix describes how to modify two vertical half-height line card slots to accept full-height line cards, such as the XGLC.

It includes the following sections:

Introduction

The ASR 5000 chassis ships with all rear line card slots configured for half-height line cards. If you are installing a full-height line card, such as the XGLC, you must prepare a full-height slot to receive it.

Full-height line cards occupy two half-height slots: an upper chassis slot and the lower chassis slot directly beneath it. For example, if a PSC2 is installed in slot 1, its corresponding XGLC would be installed in slots 17 and 33.

Important:

When entering the slot location of a full-height line card in a CLI command use the upper slot number only.


Caution

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

Remove Blanking Panels

You must remove the half-height blanking panels covering the upper and lower chassis slots, if installed.

    Step 1   Identify the chassis slots in which the full-height line card will be installed.
    Step 2   Use a Phillips #2 screwdriver to loosen the screws at the top and bottom of the blanking panel. Hold the screws on the blanking panel, and pull the blanking panel away from the chassis to expose the chassis slot.
    Step 3   Repeat step 2 to remove the half-height blanking panel covering the chassis slot directly below the slot exposed in the previous step.
    Caution   

    On a powered up chassis, do not leave chassis slots uncovered for extended periods of time. This reduces airflow through the chassis, which could cause it to overheat. Install a card or a blanking panel s in every chassis slot.

    Remove the Half-Height Card Guide

    You must next remove the half-height card guide separating the exposed upper and lower chassis slots.

    Figure 1. Half-height Card Guide

    Important:

    Save all of the items you remove in this step in the event that you wish to re-populate these slots with half-height cards at a later time.

      Step 1   Remove the two gasket strips to allow access to the screws beneath. Save the gasket strips.
      Step 2   Using a Phillips #1 screwdriver, loosen the two screws that secure the half-height card guide ejector rail/cap. Save the screws for later use.
      Step 3   Remove the half-height card guide ejector rail/cap.
      Step 4   Use the screwdriver provided with the full-height line card to loosen the screw that secures the half-height card guide to the chassis mid-plane.
      Step 5   Gently pull the half-height card guide out of the chassis.
      Important:

      You may need to slightly angle the guide when you slide it out of the chassis to unlatch it.
