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

You must remove the
half-height blanking panels covering the upper and lower chassis
slots, if installed.
Identify the chassis
slots in which the full-height line card will be installed.
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.
Repeat step 2 to remove
the half-height blanking panel covering the chassis slot directly
below the slot exposed in the previous step.
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
