Juniper EX3-SRP-IOA ERX/E-series broadband edge routers Router Module

The Juniper EX3-SRP-IOA is a Switch Route Processor (SRP), the routing-engine module for Juniper ERX/E-series broadband edge routers, providing chassis control, system-management or forwarding-control functions distinct from the interface line cards. Modules of this class are a required part of the chassis (or provide redundancy for the primary control module in dual-configuration chassis) and are typically field-replaceable, letting operators service or upgrade control-plane hardware independently of the line-card/interface layer, without disturbing installed PICs, FPCs or other interface modules elsewhere in the same chassis. Keeping a spare of the correct generation on hand is common practice for operators running this platform in production, since a control-module fault can affect the whole chassis rather than a single port. Tech-Star (UK-based, shipped worldwide) supplies this Juniper control module as used/refurbished stock for engineers maintaining existing deployments on this platform.
