Removing a Pillow Block

This section describes how to remove a damaged pillow block from the chassis. A pillow block is a
bracket with a pin that is attached to the chassis above and below each card slot. When you install or
remove a card from the chassis, the card ejector levers hook into the pillow blocks above and below the
card slot to secure the cards to the slot and allow you to install and remove the cards.
Prerequisites
Before performing this task, you must first open the front cosmetic doors (if installed). Have the pillow
block replacement kit (Cisco product number: CRS-4-PILLBLK=) at hand.
