Switch Fabric and Routing Engine (SRE) Module in an EX8208 Switch
The Switch Fabric and Routing Engine (SRE) module performs switching and system
management functions in an EX8208 switch. See Figure 7 on page 25.
You can install one or two SRE modules in an EX8208 switch. A base configuration
EX8208 switch has only one SRE module. See “EX8208 Switch Configurations” on
page 6. You can add a second SRE module to the configuration for Routing Engine and
switch control redundancy. See “Understanding EX8208 Switch Component and
Functionality Redundancy” on page 11.
The SRE modules install horizontally into the front of the chassis in slots labeled SRE0
and SRE1.
