Remove an IVC Card

Use this procedure to remove an IVC card from a vertical card-cage slot. Removing the

card while switch power is on will not damage the card.

Step Action

1. Press the MOS REQUEST button on the IVC card.

Do not remove the IVC card in an active state. Remove an IVC card

only when all its circuits are in a maintenance-out-of-service (MOS)

state. A blinking MOS indicator LED indicates that a MOS request is in

progress (and some circuits are still active). A steady MOS indicator LED

indicates that no IVC card circuits are active.

2. When the MOS indicator is steady, disengage the card lathing levers and

remove the card from its slot.

3. Place the card in an antistatic bag.
