Installing Control Cards
The card slots that house control cards are associated with specific router control system
connections. If you are installing only a primary control card, you must install the card in the slot
associated with the primary router control system connection. If you are installing both a
primary and secondary control card, both card slots are used and there is no need to distinguish.
There are no backplanes associated with control cards. All communication is through the router
control system connections.
