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:

• Remove Blanking Panels, page 2

• Remove the Half-Height Card Guide, page 2

IntroductionThe ASR 5000 chassis ships with all rear line card slots configured for half-height line cards. If you areinstalling 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 directlybeneath it. For example, if a PSC2 is installed in slot 1, its corresponding XGLC would be installed in slots17 and 33.

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

Important

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

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

Caution
