Online insertion and removal (OIR) is supported, enabling you to remove and install SIPs and SPAs
while the router is running. 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.
Each SIP and its corresponding modular services card (MSC) function as a pair. If either card is
removed, the other card is essentially powered down (although the router can still identify and
inventory the cards).
SIPs are attached to the chassis through a pair of ejector levers and captive screws. The two ejector
levers are used to release the SIP from its midplane connector. The ejector levers and captive screws
are located on the upper and bottom ends of the faceplate of the card (see
