Switch Card Modules
The VX640 contains 8 Switch Cards which are located behind the Front Door. The Switch cards are
labeled from right (Card 1) to left (Card 8). These cards contain the cross-point fabric of the router,
allowing for 8 possible paths to make connections. In the event that a Switch Card fails, some con-
nections may not be allowed.
The hot-swappable feature allows for easy replacement of a Switch Card without the need to shut
down the VX Router.
