Module Details
ERX-7xx/14xx models use up to two redundant SRP modules operating in an active/standby configuration. ERX-310 routers use only one SRP module. An SRP module must be present for any system to boot.
SRP modules ranging from 5 Gbps to 40 Gbps can be used in ERX-7xx/14xx models. Only a 10-Gbps SRP module (SRP-SE10G) can be used in ERX-310 routers. See Chapter 12, Module Specifications for complete information.
Note: Because of different physical dimensions and switch fabric capabilities, SRP modules are not interchangeable between systems. For example, the 10-Gbps SRP module used in ERX-7xx/14xx models cannot be used in the ERX-310 router, and vice versa.
