Abstract
An optical switch architecture in an optical communications network. The imminent removal of a line card from a slot at the optical switch is detected to inform an associated software process/manager that manages the line card that it is going to be removed. The movement of a locking mechanism that locks the line card in its slot triggers a message to a Node Manager that the line card is about to be removed. The software process knows that it will not be able to communicate with the line card, such as to request data or transmit commands. Moreover, the software process knows to not set an alarm for a malfunctioning line card since it will not receive any responses from the removed line card. The software process also maintains information related to the line card during its removal for use when the line card is subsequently re-installed.
