Guidelines for Card Installation and Removal

This section contains the general guidelines for card installation and removal.

Online insertion and removal (OIR) is supported, enabling you to remove and install cards while the Cisco CRS-1 4-slot line card chassis is operating. OIR is seamless to users on the network, maintains all routing information, and ensures session preservation. Notifying the software or resetting the power is not required. However, you have the option of using the shutdown command before removing a card.

The different cards in the line card chassis are all attached to the chassis itself using a pair of ejector levers and captive screws. The two ejector levers release the card from its midplane connector. The exact location of the ejector levers and captive screws varies slightly from card to card, but are in general in the same location: on the upper and bottom of the faceplate of the card. Figure 4-1shows the location of the ejector levers and captive screws on an MSC.
