The Switch Fabric (SF) module, working with the SRE module, provides the necessary switching functionality
to a base configuration EX8208 switch. The SF module is installed in the front of the chassis in the slot
labeled SF. In a redundant configuration, the SF module provides full 2+1 switch fabric redundancy to the
switch. See "Switch Fabric (SF) Module in an EX8208 Switch" on page
The EX8208 switch can also be connected to an XRE200 External Routing Engine. An XRE200 External
Routing Engine is used to connect multiple EX8200 switches into a Virtual Chassis. See XRE200 External
Routing Engine Hardware Overview.

Line Cards

The EX8208 switch features eight horizontal line card slots and supports line rate for each line card. The
line cards in EX8200 switches combine a Packet Forwarding Engine and Ethernet interfaces on a single
assembly. Line cards are FRUs that can be installed in the line card slots labeled 0 through 7 on the front
of the switch chassis. See
hot-removable and hot-insertable.
Twelve line cards are available for EX8200 switches. The extra-scale line card models provide larger IPv4
and IPv6 route table sizes than the non-extra-scale models to store more unicast routes.
