The Juniper Networks EX8208 Ethernet Switch is available as a fully redundant system. A redundant
EX8208 switch configuration is designed so that no single point of failure can cause the entire switch to
fail. See "EX8208 Switch Configurations" on page

Hardware Components That Provide Redundancy

The following hardware components provide redundancy to an EX8208 switch:
SRE modules-An EX8208 switch can have either one Switch Fabric and Routing Engine (SRE) module
or two SRE modules. If two SRE modules are installed, one SRE module functions as the primary and
the other functions as the backup. If the primary SRE module fails or is removed the backup module
takes over as the primary SRE module.
