Complete Hardware Guide for EX8208 Ethernet Switches

NOTE: Line cards are not part of the base or redundant configuration. You must order them separately.

NOTE: If you have a Juniper J-Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/csc/management/updateinstallbase.jsp. Failure to do so can result in significant delays if you need replacement parts. This note applies if you add a new type of line card. It does not apply if you replace these components with the same type of component.

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.
